<p>A variable-displacement swash-plate compressor comprising a cylinder housing (101) having a plurality of cylinder bores (122) and a crank chamber (110) in which a swash plate (113) is disposed to be coupled to a drive shaft (109) with a variable slant angle for driving pistons (123) slidably fitted into the cylinder bores (122), a cylinder head mounted on the cylinder housing (101) and having a suction chamber (132) and a discharge chamber (133) selectively connected to the cylinder bores (122), and a crank chamber pressure control system for controlling an inner pressure of the crank chamber (110) to control the slant angle of the swash plate (113) to thereby control a fluid displacement volume of the compressor, by detecting the crank chamber pressure by use of a pressure detector (142) disposed in a pressure detecting chamber (140) formed in the cylinder head (131) and communicating with the crank chamber (110) through a communicating path (156). In order to simplify provision of the communicating path, a communicating member (155) having a through hole (156) extending therethrough is assembled to be disposed bridging between the cylinder housing (100) and the cylinder head (131), the through hole providing the communicating path to communicate the crank chamber (110) with the pressure detecting chamber (140). <IMAGE></p> |
