  • Patent number: 11156215
    Abstract: A portable hydraulic-powered air compressor system detachably connected to a hydraulic power system of a vehicle may include a reciprocating compressor. The reciprocating compressor may include a compression cylinder, and a compressor piston assembly that may be movably disposed within the compression cylinder. Opposite sides of the compressor piston assembly may respectively define a rod chamber and a front chamber in an interior of the compression cylinder. The front chamber may include an air intake port. The compressor piston assembly may include a one-way valve that may be configured to fluidically connect the rod chamber and the front chamber in response to an air pressure in the front chamber being higher than an air pressure in the rod chamber. The hydraulic-powered air compressor system may further include a hydraulic actuating mechanism detachably connected to the hydraulic power system.
