Abstract: A belt guard for an air compressor that includes an air compressor silencer. The guard includes a housing that includes a front cover and a back cover, and an accommodation portion. The air compressor silencer is provided inside the housing in the accommodation portion, where the air compressor silencer includes a spirally shaped silencer core, and the spirally shaped silencer core includes at least one spiral chamber comprising a core inlet and a core outlet. Additionally, a compressor installation that includes a motor, a compressor, a belt connected to a compressor shaft of the compressor element and a motor shaft of the motor, and a belt guard that includes a front cover and a back cover, and an accommodation portion, where the compressor silencer is provided inside the housing in the accommodation portion.

Abstract: A compressor installation having a reduced load at start-up, including a gas compressor having an inlet and an outlet and a start-up valve connected to the outlet of the compressor. The start-up valve includes a valve body having an inlet and an outlet, a valve plunger connected to the inlet of the valve body, a spring connected to the valve body and the valve plunger, and a muffler. The start-up valve is configured to discharge the compressed gas through the muffler to atmosphere to reduce the load on the motor at start-up. After starting the compressor, the spring in the start-up valve is compressed after pressure is increased by the compressor and the discharge through the start-up valve to atmosphere is closed.

Abstract: A noise reducing silencer for a compressor, the silencer including a housing, a spirally shaped silencer core provided in the housing and having an inlet and an outlet, a connecting element connected to the silencer core to connect the outlet of the silencer core to an inlet of a compressor. The silencer core is provided to reduce noise during operation of the compressor, where the silencer core can include two spiral chambers stacked on each other. The spiral chambers can also include hollow walls that form the spiral chambers and that are filled with sound absorbing material.

Abstract: A silencer for a compressor, the silencer including a housing, a spirally shaped silencer tube provided in the housing and having an inlet and an outlet, a connecting element connected to the silencer core to connect the outlet of the silencer core to an inlet of a compressor. The silencer tube is provided to reduce noise during operation of the compressor.

Abstract: A continuous run controller for a dual control compressor system includes an integrated housing containing a pilot valve and a hydraulic unloader valve. Low pressure in the hydraulic oil system opens the hydraulic unloader valve such that the suction valve unloader assembly unloads the compressor. High pressure in an air receiver of the compressor system opens the pilot valve such that the suction valve unloader assembly unloads the compressor.

Abstract: A connecting rod assembly including a connecting rod, a bushing with an inner surface and an outer surface, and a pin connectively coupled to the piston and the connecting rod at the small end. The bushing contacts the pin on the inner surface and the connecting rod on the outer surface. The bushing may be self-lubricate when the bushing moves rotationally with respect to the connecting rod.

Abstract: In one embodiment, a connecting rod assembly is described. The connecting rod assembly may comprise a connecting rod, a bushing with an inner surface and an outer surface, and a pin connectively coupled to the piston and the connecting rod at the small end. The bushing may contact the pin on the inner surface and the connecting rod on the outer surface.
