Patent number: 9759206Abstract: A swash plate type variable displacement compressor includes a collection and supply mechanism. The collection and supply mechanism has collection passages, supply passages, an annular space, an inlet port, and an outlet port. The inlet port is communicable with a working collection passage of the collection passages. The outlet port is communicable with a working supply passage of the supply passages. When the inclination angle of the swash plate is maximum, residual refrigerant gas in a compression chamber of collection phase is collected through the working collection passage and the collected refrigerant gas is supplied to a compression chamber of supply phase. On the other hand, when the inclination angle is less than the maximum, residual refrigerant gas is supplied no more into the supply-phase compression chamber.Type: GrantFiled: September 23, 2014Date of Patent: September 12, 2017Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Yoshio Kimoto, Toru Onishi, Kengo Sakakibara, Yuki Yokoi, Takahisa Ban, Ryo Matsubara, Noriyuki Shintoku

Patent number: 6039007Abstract: In the heater of the present invention, a heating chamber accommodates a viscous fluid. A rotor is located in the heating chamber. The rotor rotates and shears the viscous fluid to generate heat. The heat generated in the heating chamber is transferred to the heat exchanger and heats a fluid that flows through the heat exchanger. A reservoir stores the viscous fluid. The reservoir has an upper portion and a lower portion, and the lower portion has a greater volume than the upper position. A return passage connects the heating chamber to the reservoir so that the viscous fluid moves from the heating chamber to the reservoir when the rotor rotates. A supply passage connects the reservoir to the heating chamber so that the viscous fluid flows from the reservoir to the heating chamber.Type: GrantFiled: January 4, 1999Date of Patent: March 21, 2000Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Takashi Ban, Tatsuyuki Hoshino, Takanori Okabe, Takahisa Ban
