A compressor which provides for minimum clearance in the compression chamber while substantially reducing the heat normally experienced by the piston during the compression stroke of a compressor of this type. The suction valve(s) of the compressor is concentrically mounted in the piston while the discharge valve(s) is concentrically mounted in a stationary position within the cylinder. Since the high heat of compression occurs at the discharge valve, the piston will be much cooler than in prior art compressors of this type which improves the efficiency of the compressor and which substantially extends the operational life of the piston rings.

A compressor comprising: a cylinder having a first section having a first inlet and a first outlet and a reduced-diameter section having a second inlet and a second outlet; means for connecting said first inlet to a gas supply; a first discharge valve having a bore therethrough mounted in said first section of said cylinder for controlling flow from said first section of said cylinder through said first outlet; a second discharge valve mounted in said reduced-diameter section of said cylinder for controlling flow from said reduced-section of said cylinder through said second outlet; a piston rod slidably mounted through said bore in said first discharge valve in said cylinder; a second piston mounted on the end of said piston rod and positioned for reciprocating movement within said reduced section of said cylinder and defining a second compression chamber between said second piston and said second discharge valve; a first piston mounted on said piston rod and positioned for reciprocating movement within said first section of said cylinder and spaced from said second piston to thereby form an inlet chamber between said pistons which is adapted to receive flow from said first inlet; said first piston forming a first compression chamber between said first piston and said first discharge valve; a suction valve mounted in and carried by said first piston for controlling flow from said inlet chamber into said first compression chamber; and means for fluidly connecting said first outlet to said second inlet of said cylinder.
