    摘要： An air compressor apparatus is disclosed that includes an air tank. A first compressor assembly can be fluidly coupled to the air tank, the first compressor assembly including a first head unloader valve. A second compressor assembly can be fluidly coupled to the air tank, the second compressor assembly including a second head unloader valve. A control unit can be electrically coupled to the first and second compressor assemblies, the control unit operable to control the operation of the first and second compressor assemblies. During startup, the first and second air compressor assemblies can be configured to draw less than 20 amps of current combined from a single 120 volt power source. The first and second compressor assemblies can each be dual piston compressor assemblies.

    摘要： High pressure pumps and associated check valves for use with, e.g., waterjet systems, are disclosed herein. In some embodiments, high pressure pumps configured in accordance with the present disclosure include check valve assemblies that eliminate threaded parts for restricting the motion of check valve components which are subjected to very high pressure variations at relatively high frequencies. Additionally, embodiments of the pumps described herein can include unitary structures that integrate the individual parts associated with multiple cylinders (e.g., cylinders, check valve bodies, etc.) into a single part (e.g., a cylinder manifold, check valve manifold, outlet manifold, etc.) that can substantially reduce the number of different parts required to assemble the pump.
