PURPOSE: To simplify the structure of the titled compressor by a method wherein a relief hole in the rear surface of a spool is opened or closed by a pilot valve which is loosely fixed to a rod operated by an electromagnet so that the movement of the rod is transmitted to the spool without the intermediary of the pilot valve.
CONSTITUTION: A discharge chamber 35 and an operation chamber 70 are made to communicate with each other through a pressure introducing hole 71 drilled through a rear housing 19, the operation chamber 70 is made to communicate with swash plate chamber 21 through the relief hole 72 of the spool 59, communication holes 63, 44a and an axial hole 15a and the relief hole 72 is opened and closed by the pilot valve attached to the top end of the rod 74 operated by the electromagnet 68. As a consequence, the transmission of the operation of the rod to the spool 59 is made possible without the intermediary of the pilot valve 78 by the provision of only a single valve mechanism including the spool 59, the relief hole 72, the rod 74 and the pilot valve 78 so that the structure of the compressor is simplified to thereby reduce the manufacturing cost and the leakage of a gas is prevented.
