Prestressed resilient compressor mount apparatus

A resilient mount for supporting and attenuating the operational vibration of a machine having a base member with an opening therein, said resilient mount extending alone an axis and comprising:

• an upper portion extendable through the base member opening;
• a lower portion restable on a support surface and coaxial with said upper portion;
• an intermediate portion interconnecting said upper and lower portions;
• and
• a tightening opening, extending axially through said upper, lower and intermediate portions, for receiving a tightening member operative to axially compress said resilient mount,
• said resilient mount being configured to permit said upper portion to be moved toward said lower portion, to thereby resiliently squeeze a portion of the machine base member between said upper and lower portions, without substantially compressing said intermediate portion of said resilient mount,
• said lower portion having a flexible interior annular flange having an axial thickness substantially less than the axial thickness of said upper portion, and
• said intermediate portion extending upwardly from a central annular portion of said flange and connecting said upper portion thereto, said flexible interior annular flange being downwardly deflectable by said intermediate portion, in response to resiliently squeezing a portion of the machine base member between said upper and lower portions, in a manner substantially preventing axial compression of said intermediate portion.

A resilient mount for supporting and attenuating the operational vibration of a machine having a base member with an opening therein, said resilient mount extending along an axis and comprising:

• an upper portion extendable through the base member opening;
• a lower portion restable on a support surface and coaxial with said upper portion;
• an intermediate portion interconnecting said upper and lower portions;
• and
• a tightening opening, extending axially through said upper, lower and intermediate portions, for receiving a tightening member operative to axially compress said resilient mount,
• said resilient mount being configured to permit said upper portion to be moved toward said lower portion, to thereby resiliently squeeze a portion of the machine base member between said upper and lower portions, without substantially compressing said intermediate portion of said resilient mount,
• said resilient mount being of a two piece construction,
• said upper portion being separate from said lower portion, and
• said intermediate portion being defined by first and second hollow tubular projections respectively formed on said upper and lower portions and telescopingly and slidingly engageable with one another, said first and second hollow tubular projections being axially movable relative to one another, in response to the resilient squeezing of a portion of the machine base member between said upper and lower portions, to thereby prevent the creation of a substantial axial stress in said intermediate portion.

A resilient mount for supporting and attenuating the operational vibration of a machine having a base member with an opening therein, said resilient mount extending along an axis and comprising:

• an upper portion extendable through the base member opening;
• a lower portion restable on a support surface and coaxial with said upper portion;
• an intermediate portion interconnecting said upper and lower portions;
• and
• a tightening opening, extending axially through said upper, lower and intermediate portions, for receiving a tightening member operative to axially compress said resilient mount,
• said resilient mount being configured to permit said upper portion to be moved toward said lower portion, to thereby resiliently squeeze a portion of the machine base member between said upper and lower portions, without substantially compressing said intermediate portion of said resilient mount,
• said lower portion having a bottom end and a series of openings extending upwardly through said bottom end and being circumferentially spaced around said tightening opening.

An elastomeric compressor mount for supporting and attenuating the operational vibration of a compressor having a mounting foot portion with a circular opening therein, said compressor mount extending along an axis and comprising:

• an upper portion upwardly extendable through the compressor foot opening, said upper portion having a hollow configuration, a substantially uniform wall thickness, and a downwardly and radially inwardly sloping annular bottom side;
• a lower portion restable on a support surface and spaced apart along said axis from said upper portion;
• an intermediate portion interconnecting said upper and lower portions;
• and
• a tightening opening, extending axially through said upper, lower and intermediate portions, for receiving a tightening member operative to axially compress said resilient mount in a manner resiliently squeezing an annular portion of the compressor foot between said upper and lower portions of said compressor mount.

An elastomeric compressor mount for supporting and attenuating the operational vibration of a compressor having a mounting foot portion with a circular opening therein, said compressor mount extending along an axis and comprising:

• an upper portion upwardly extendable through the compressor foot opening;
• a lower portion restable on a support surface and coaxial with said upper portion, said lower portion having a flexible interior annular flange circumscribing said axis and having an axial thickness substantially less than the axial thickness of said upper portion;
• an intermediate portion interconnecting central sections of said upper portion and said internal flange;
• and
• a tightening opening, extending axially through said upper, lower and intermediate portions, for receiving a tightening member operative to axially compress said compressor mount in a manner resiliently squeezing a portion of the compressor foot between said upper and lower portions by moving said upper portion toward said lower portion and downwardly deflecting said internal flange, the downward deflection of said internal flange serving to substantially prevent the axial compression of said intermediate portion.

A two piece elastomeric compressor mount for supporting and attenuating the operational vibration of a compressor having a mounting foot portion with a circular opening therein, said compressor mount being positionable to extend along an axis and comprising:

• an upper portion extendable through the compressor foot opening;
• a lower portion positionable below said upper portion, in a spaced relationship therewith along said axis, and restable on a support surface, said lower portion being separate from said upper portion,
• said upper and lower portions having central, outwardly projecting sections which are slidably telescopable with one another, the telescoped sections defining an intermediate, axially extending portion of said mount which interconnects said upper and lower portions and permits them to be axially moved toward one another;
• and
• a tightening opening, extending axially through said upper and lower portions when they are slidingly telescoped with one another, for receiving a tightening member operative to axially compress said compressor mount in a manner moving said upper portion toward said lower portion to resiliently squeeze a portion of the compressor foot between said upper and lower portions of said compressor mount and responsively create relative axial movement between said telescoped sections in a manner thereby preventing the creation of substantial axial stress in said intermediate portion of said mount when the compressor foot is resiliently squeezed between said upper and lower portions of said compressor mount.
