Abstract
The invention relates to a compressor, which comprises a cylinder, a piston in the cylinder, inflow check valves, outflow check valves and the like. The cylinder, the piston in the cylinder, the inflow check valves and the outflow check valves form at least two working cavities which alternate from an expanding state to a compressing state. Inflow ends of at least two inflow valves mounted on each of end caps of the cylinder of the compressor are communicated by inflow pipelines so as to form an inflow port of the compressor, and outflow ends of the inflow check valves are communicated with the working cavities respectively. Outflow ends of at least two outflow valves mounted on the end caps of the cylinder of the compressor are communicated by outflow pipelines so as to form an outflow port of the compressor, and inflow ends of the outflow check valves are communicated with the working cavities respectively. Backpressure action generated from residual pressure of a fluid circulation system or higher pressure of input fluid to the piston can be effectively utilized to reduce input of external power, so that consumption of fossil energy can be reduced.
