Abstract
A cylinder of a piston compressor comprises a piston movable along the axis of the cylinder, a cylindrical admission valve and a cylindrical delivery valve. The admission valve communicates an admission space of the cylinder with a working space thereof. The delivery valve communicates the working space of the cylinder with a delivery space thereof. At least one valve, for instance the admission valve has means providing the control of the capacity of the cylinder, the movable member of said means being coaxially arranged inside the cylindrical admission valve.
Claims6
An arrangement for controlling the capacity of a piston compressor comprising:
- a piston axially movable in said cylinder;
- an admission space in said cylinder;
- a working space in said cylinder, cylindrical admission valves, each communicating said admission space of said cylinder with the working space thereof;
- annular elastic notched laminae of each of said cylindrical admission valves;
- annular rigid seats of each of said cylindrical admission valves;
- said seats having passages for the flow of the fluid being compressed;
- said annular elastic notched laminae and said annular rigid seats alternating with one another;
- a delivery space of said cylinder;
- cylindrical delivery valves, each communicating said delivery space of said cylinder with said working space thereof;
- annular elastic notched laminae of each of said cylindrical delivery valves;
- annular rigid seats of each of said cylindrical delivery valves;
- said seats having passages for the flow of the compressed fluid, said annular elastic notched laminae and said annular rigid seats alternating with one another;
- a volume reducing cone adjacent to said admission valves and said delivery valves for reducing dead space in said valves;
- and means cooperating with one of said cones for adjusting the output of said cylinder.
