  • Patent number: 11053931
    Abstract: The present invention is directed to a dual engine-compressor system having a crankcase enclosing a crankshaft and having engine cylinder housings and compressor cylinder housings linearly disposed on opposite sides of the crankcase. Combustion pistons are reciprocatingly disposed in the engine cylinder housings and defines alternating combustion chambers on opposite sides of the pistons. Compressor pistons are reciprocatingly disposed in the compressor housings and define alternating low and high pressure compressor chambers on opposite sides of the compressor pistons. The compressor pistons undergo a 4-cycle process to drawn in, re-distribute, and then compress fluid. The compressor cylinder and piston has a series of one-way intakes and reed valves to selectively draw or push fluid in response to movement of the compressor piston.

  • Patent number: 11035354
    Abstract: A peristaltic pump comprises a drive assembly, a hose pump, and a hose bracket. The drive assembly is rotatably disposed within a frame to move a roller along a pumping path with respect to the frame. The pump hose has rigid hose ends connected by a bendable hose section with limited flexibility tending to bias the pump hose towards a substantially unbent shape. The hose bracket has a rigid body with a first central opening sized to receive the rigid hose ends at first and second retention locations, such that the natural bias of the pump hose towards a substantially unbent shape retains the hose ends within the first and second retention locations, positioning the bendable hose section along the pumping path of the roller.

  • Patent number: 11028837
    Abstract: A solenoid pump that includes a base and a solenoid having a coil and a pole piece. A retainer body, positioned inside the solenoid and the base, includes an armature cavity that receives an armature in a sliding fit for movement between energized and de-energized positions. A diaphragm, mounted in the armature cavity, is connected to the armature. An inlet check valve permits fluid flow in only a first direction moving from an inlet port toward the diaphragm. An outlet check valve permits fluid flow in only a second direction moving from the diaphragm toward an outlet port. A fluid flow path extends through the retainer body from the inlet check valve to the diaphragm and from the diaphragm to the outlet check valve for transporting fluid from the inlet check valve to the outlet check valve as the diaphragm oscillates between first and second positions.
