Abstract
Disclosed is a vacuum preventing device including a housing engaged to one side of an outer circumference portion of a fixed scroll to divide the area into a discharge region and a suction region, a chamber formed in the housing and having a compression hole connected to a compression region at one side therein, a suction hole connected to a suction region at the other side therein, and a discharge hole connected to a discharge region at a middle side therein, an open/close member is movably installed in the chamber to selectively connect the discharge hole to the suction hole, and an elastic member is installed in the chamber to provide an elasticity force to the open/close member.
Claims20
A vacuum preventing device for a scroll compressor comprising:
- a housing engaged with one side of an outer circumferential portion of a fixed scroll to define a discharge region and a suction region;
- a chamber formed in the housing and having a compression hole connected to a compression region at one side therein, a suction hole connected to a suction region at the other side therein, and a discharge hole connected to a discharge region at a middle side therein;
- an open/close member movably installed in the chamber to selectively connect the discharge hole to the suction hole;
- and
- an elastic member installed in the chamber to provide an elasticity force to the open/close member,
- wherein in an abnormal driving condition, the open/close member is positioned to connect the discharge hole to the suction hole by the elasticity force of the elastic member being stronger than a pressure applied through the compression hole, and in a normal driving condition, the open/close member is positioned to obstruct the suction hole by a balance between the elasticity force of the elastic member and the pressure applied through the compression hole.
A vacuum preventing device for a scroll compressor comprising:
- a housing engaged with one side of an outer circumferential portion of a fixed scroll to define a discharge region and a suction region;
- a chamber formed in the housing and having a compression hole connected to a compression region at one side therein, a suction hole connected to a suction region at the other side therein, and a discharge hole connected to a discharge region at a middle side therein;
- an open/dose member movably installed in the chamber to selectively conned the discharge hole to the suction hole;
- and
- an elastic member installed in the chamber to provide an elasticity force to the open/close member,
- wherein a protrusion to close and open the compression hole is formed at one side of the open/close member.
A vacuum preventing device for a scroll compressor comprising:
- a housing engaged with one side of an outer circumferential portion of a fixed scroll to define a discharge region and a suction region;
- a chamber formed in the housing and having a compression hole connected to a compression region at one side therein, a suction hole connected to a suction region at the other side therein, and a discharge hole connected to a discharge region at a middle side therein;
- an open/close member movably installed in the chamber to selectively connect the discharge hole to the suction hole;
- and
- an elastic member installed in the chamber to provide an elasticity force to the open/close member,
- wherein the open/close member moves in an opening direction of the compression hole and discharge hole, the elastic member is installed in an opening direction of the compression hole and discharge hole, and the elastic member is installed adjacent to the discharge hole.
