<p>PURPOSE:To prevent abnormal abrasion of the check valve and the valve seat of a variable capacity compressor and prevent bending of the root of the rod of the check valve by supporting the valve seat by an O-ring and setting a gap between a cylinder block and the valve seat. CONSTITUTION:A load/unload switching mechanism is installed at one discharge port 16F, 16R on the front side or the rear side. The top edge part of a discharge passage 30R which is extended from the both discharge ports 16F and 16R is allowed to communicate to the inside of a discharge flange 29. A check valve 32 is installed so as to be opened and closed freely, opposed to the direction of feed of the discharged gas, in the discharge passage 30R extended from the discharge chamber on the side equipped with a load/unload switching mechanism, and a valve seat 31 onto which the check valve 32 collides in the case when switching from loaded state to unloaded state is performed is supported by an elastic O-ring 34, and a gap is set between a cylinder block 2 and the valve seat 31.</p> |
