摘要： A piston assembly for a compressor that reduces the temperature experienced by a compressor cup seal during operation of the compressor. The piston assembly includes a piston sleeve having a top portion and an interior. A valve plate is supported by the top of the piston sleeve. A compressor head includes a compressor head plate, which is offset from the valve plate. The offset between the compressor head plate and the valve plate defines a cooling chamber. The interior of the piston sleeve communicates with the interior of the compressor head via openings defined in the valve plate and the compressor head plate and conduit associated with these opening and traversing the cooling chamber.

摘要： A muffler assembly for muffling noises associated with a compressor. The muffler assembly is mounted on the compressor such that the two move as a solid body. The muffler assembly includes an intake having a hollow interior adapted to receive a first flow of gas from the ambient environment. A baffle disposed in the hollow interior of the intake restricts the flow of gas through the intake. In one embodiment, the baffle defines at least a portion of a plurality of fluid portals that separate the first flow of gas into a plurality of flows of gas as the gas passes from a first side of the baffle to a second side of the baffle. As a result, the first flow of gas is disturbed and noise from the compressor is thereby attenuated. In another embodiment, a plurality of baffles are disposed in the hollow interior of the intake to define a tortuous path for the flow of gas through the intake for attenuating noise.

摘要： A muffler assembly for muffling noises associated with a compressor. The muffler assembly includes an air intake having a hollow interior for receiving air from the ambient environment when the compressor is operating. A baffle is located within the interior of the intake for restricted passage of the air through the intake. A fluid portal is defined within the baffle for enabling fluid to pass from one side of the baffle to the other side of the baffle and subsequently through said air intake. An attenuator is disposed within the fluid portal for attenuating noise and the attenuator disturbs the soundwaves associated with the operation of the compressor.
