Title: Slant plate type compressor with variable capacity control mechanism
Inventor: TAGUCHI YUKIHIKO
IPC: F04B49/00
Filed: 1992-10-07
Granted: 1997-06-10
Abstract: A variable capacity type slant plate type compressor including a crank chamber, a suction chamber and a discharge chamber is disclosed. The crank chamber is linked by a first communication path to the suction chamber, and is linked by a second communication path to the discharge chamber. A first valve control mechanism is disposed within the first communication path and second valve control mechanism is disposed within the second communication path. Fluid communication between the crank and suctionchambers is controlled by the first valve control mechanism so that the suction chamber pressure is maintained at one predetermined constant value while fluid communication between the crank and discharge chambers is continuously closed. Fluid communication between the crank and discharge chambers is opened by the second valve control mechanism when the predetermined constant value of the suction chamber pressure must be increased. However, in the latter condition, fluid communication between the crank and suction chambers is continuously closed as long as the crank chamber pressure is not abnormally increased.
