Embodiment Construction

[0024] refer to figure 2 , an embodiment of a variable displacement compressor of the present invention is described.

[0025] The variable displacement compressor shown is for compressing a refrigerant gas and comprises a housing 11, a main shaft or mandrel 12 received in the housing 11, and a front casing 13 mounted at one end of the housing 11. The spindle 12 has one end extending outwardly through the front housing 13 to be connected to an external power source (not shown) through an electromagnetic clutch 14 .

[0026] Inside the housing 11, a set of cylinder bores 15 are arranged at intervals from each other in the circumferential direction. Each cylinder bore 15 is equipped with a piston 16 which can slide inside. The piston is connected to the spindle 12 by a crank mechanism 17 and reciprocates in the cylinder bore 15 as the spindle 12 rotates. The piston 16 has a stroke that is variably controlled by a crank mechanism 17 .

[0027] The cylinder head 19 is fixed t...

Abstract

In a variable displacement compressor of a piston type, a valve body (34) is movably placed adjacent to a main channel (32) communicating a suction port (26) with a suction chamber (24). The valve body is for variably controlling an opening area of the main channel. An air damper (38) is coupled to the valve body to damp vibration of the valve body. In addition, a bypass channel (39) is formed outside of the air damper to communicate the suction port with the suction chamber.

Description

technical field [0001] The present invention relates to a piston type variable displacement compressor. Background technique [0002] The variable displacement compressor includes a piston that is reciprocally driven within a cylinder bore. The piston has suction and compression strokes which are repeated alternately to compress a gaseous fluid, such as refrigerant gas. During the suction stroke, gaseous fluid is drawn into the cylinder bore through a suction part and a suction chamber of the compressor. During the compression stroke, gaseous fluid is compressed into a compressed fluid in the cylinder bore. The compressed fluid is expelled from the cylinder bore to the discharge chamber of the compressor. In the variable displacement version, it is assumed that the compressed fluid produces pressure pulsations when the flow velocity of the fluid being compressed is relatively low. [0003] For example, a variable displacement compressor is disclosed in U.S. Patent Serial...
