  • Air compressor
    Patent number: 5515769
    Abstract: An oilless reciprocating compressor for use in a refrigerated controlled atmosphere has an uncooled, fully sealed crankcase. A bypass tubing connects the interior of the crankcase with the inlet of the cylinders, so that blow-by is returned from the crankcase to the inlet of the cylinder for recirculation. In consequence no blow-by gas escapes into the controlled atmosphere. The device includes standard pistons, and has an improved cylinder head seal utilizing o-rings.

  • Mounting for oilless air compressor
    Patent number: 5419688
    Abstract: An oilless reciprocating air compressor that is mountable on the inside wall of a cargo container. The compressor has a high strength cast metal crank case and a lighter motor housing attached thereto. A special bracket is provided that attaches to both the crank case and the motor housing to support the motor shaft in a horizontal plane and the opposed cylinders of the compressor in a vertical plane adjacent to the wall. Because this compressor mounted inside the container cooling fans and the like are not required, thus lightening the compressor and allowing for a compact unit that can be safely secured to the cargo container wall.

  • Oscillating cylinder pumping arrangement
    Patent number: 4822254
    Abstract: A pumping arrangement includes an electric motor which has an output shaft having a shaft portion that projects out of the stator of the motor, a crankcase which surrounds the shaft portion and includes an outwardly projecting piston component that is stationary with respect to the motor stator, a cylinder component which is arranged around the piston component, an eccentric element which is mounted on the shaft portion for rotation therewith, an annular force-transmitting element which surrounds the eccentric element, and two connecting units which connect the cylinder component with the force-transmitting element at the opposite sides of the piston component and cause the cylinder component to perform a reciprocating and oscillating movement on the piston component as the force-transmitting element is moved eccentrically with respect to the longitudinal axis of the output shaft by the eccentric element.
