Abstract
A compressor assembly having a tank seal which seals a tank gap between a portion of a housing of the compressor assembly and a portion of a compressed gas tank and a method for controlling the sound level of a compressor assembly by configuring a tank seal to seal a gap between the housing of a compressor assembly and a compressed gas tank. The sound level of the compressor assembly can be controlled by sealing a tank gap between at least a portion of a compressor assembly housing and at least a portion of a compressed gas tank.
Claims20
A compressor assembly, comprising:
- a housing which encloses at least in part each of a pump assembly and a universal motor having a motor speed in a range of 5,000 rpm to 20,000 rpm,
- said pump assembly having a reciprocating pump that is driven by a drive belt, said housing having a bottom housing portion which is proximate to a convex outer shell portion of a compressed gas tank;
- a tank gap between said bottom housing portion and the convex outer shell portion of the compressed gas tank;
- a tank seal which seals a portion of said tank gap between said bottom housing portion and at least a portion of the convex outer shell portion of said compressed gas tank and which contributes a sound reduction in a range of from 0.5 dBA to 15 dBA from the sound emitted from the compressor assembly when the compressor assembly is in a compressing state and that is measured in compliance with ISO3744-1995;
- and
- the compressor assembly having a sound level which is in a range of from 65 dBA to 75 dBA when the compressor assembly is in a compressing state and that is measured in compliance with ISO3744-1995.
A method for controlling the sound level of a compressor assembly, comprising the steps of:
- providing the compressor assembly having a pump assembly having a reciprocating pump that is driven by a drive belt and having a housing which encloses at least in part each of the pump assembly and a universal motor,
- said housing having a bottom housing portion having a housing rim and enclosing at least in part each of the pump assembly and the universal motor;
- providing a compressed gas tank having a convex outer shell portion;
- configuring the housing and the compressed gas tank to have a tank gap between the bottom housing portion and the convex outer shell portion of the compressed gas tank, said bottom housing portion proximate to a portion of said compressed gas tank;
- providing a tank seal configured between the housing rim and the convex outer shell portion of the compressed gas tank;
- and
- at least in part sealing a portion of the tank gap with the tank seal,
- wherein the tank seal contributes a sound reduction in a range of from 0.5 dBA to 15 dBA from the sound emitted from the compressor assembly when the compressor assembly is in a compressing state and that is measured in compliance with ISO3744-1995.
A compressor assembly, comprising:
- a housing portion which encloses at least in part each of a pump assembly and a universal motor having a motor speed in a range of 5,000 rpm to 20,000 rpm, said housing portion having a bottom housing portion which is proximate to at least a portion of a compressed gas tank;
- a tank gap between at least a portion of the bottom housing portion and a convex portion of the compressed gas tank;
- a means to seal a portion of the tank gap which contributes a sound reduction in a range of from 0.5 dBA to 15 dBA from the sound emitted from the compressor assembly when the compressor assembly is in a compressing state and that is measured in compliance with ISO3744-1995;
- and
- wherein said pump assembly has a reciprocating pump that is driven by a drive belt;
- wherein said compressor assembly has a sound level in a range of from 65 dBA to 75 dBA when the compressor assembly is in a compressing state and that is measured in compliance with ISO3744-1995.
