FIELD: engines and pumps.
SUBSTANCE: proposed device is intended for compressor production and piston-type gas pumps. Gas pump comprises open-end face cylinder. Pressure chamber is arranged aligned with the cylinder, its inlet hole being communicated with the cylinder open end face. The cylinder houses piston. Cylinder open end face is arranged with a gap relative to pressure chamber. Cylinder represents a tube open on both ends and has its open end face edge, distant from the piston, is rounded towards tube inner wall. Edge roundness radius makes 24 to 26 mm.
EFFECT: higher efficiency, reduced power consumption.
