Patent number: 9903352Abstract: A swash plate type variable displacement compressor includes a housing in which a suction chamber, a discharge chamber, a swash plate chamber, and a cylinder bore are formed, a drive shaft, a swash plate, an actuator, and a control mechanism that controls the actuator. A pressure regulation chamber is formed in the housing. The actuator includes a control pressure chamber. The control mechanism includes a control passage that connects together the discharge chamber, the pressure regulation chamber, and the control pressure chamber, and a control valve that, by adjusting the degree of opening of the control passage, changes the pressure in the control pressure chamber to allow the movable body to move. Refrigerant in the discharge chamber flows into the control pressure chamber via the pressure regulation chamber. The pressure regulation chamber functions as a muffler that reduces the pulsation of the refrigerant.Type: GrantFiled: November 1, 2013Date of Patent: February 27, 2018Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Hiroyuki Nakaima, Shinya Yamamoto, Takahiro Suzuki, Masaki Ota, Kazunari Honda, Kei Nishii, Yusuke Yamazaki
