More Information
Summary:A reciprocating compressor includes double headed pistons forming front and rear sets of compression chambers on either side thereof and a pair of tapered rotary valves arranged for introducing a coolant gas into the compression chambers. The valves are urged into contact with valve chambers by springs and a drive shaft is urged in one axial direction by a prestress mechanism. The valve urging force for one rotary valve is different from the valve urging force for the other rotary valve, so that the rotary valves operate at different times and over different distances and the movements of the rotary valves are controlled to move the drive shaft in the same axial direction as the direction of the prestress mechanism.
