This form of air compressor makes use of ideas of displacement to boom the strain of the enclosed extent of fueloline or air. They are to be had in more than a few configurations, from single-performing, double-performing, oil-lubricated or oil-loose. A not-unusual place configuration is a double-performing design, which functions as an L-configuration with one vertical, low-strain cylinder and one horizontal, high-strain cylinder. The oil-lubricated designs use splash lubrication or strain lubrication and oil-loose designs function as piston earrings or toothed walls.
