Patent number: 6637223Abstract: A control apparatus that promptly increases the displacement of a compressor after the compressor is started while liquefied refrigerant is lingering in an external circuit. The control apparatus includes a restricting passage. The restricting passage is located in a first pressure introduction passage, through which the pressure of the first pressure monitoring point flows to the control valve. The restricting passage decreases the pressure of refrigerant that flows through the passage. When the compressor is started while liquefied refrigerant is lingering in the external circuit and the pressure of the first pressure monitoring point is abruptly increased, the restricting passage reduces the increase of the pressure that is detected by the control valve. Therefore, the displacement of the compressor is promptly increased.Type: GrantFiled: November 7, 2001Date of Patent: October 28, 2003Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Masaki Ota, Kazuya Kimura, Yoshinobu Ishigaki, Kazuhiro Nomura, Tomoji Tarutani, Masahiro Kawaguchi

Patent number: 6247902Abstract: A mechanism for attenuating torsional vibration in a compressor is described. The compressor includes a swash plate secured to a drive shaft and pistons coupled to the swash plate. Compression of refrigerant gas by the pistons generates torsional vibrations of the drive shaft. The rear end of the drive shaft is coupled to a damper for attenuating torsional vibrations. The damper includes a frictional plate secured to the rear end of the drive shaft, a weight rotatably fitted about the drive shaft, and a coil spring. The coil spring elastically presses the weight against the frictional plate and elastically couples the weight with the drive shaft. When the drive shaft torsionally vibrates, the weight contacts the frictional plate and is vibrated about the axis of the drive shaft by the coil spring. As a result, energy of the torsional vibrations is consumed and the vibrations are attenuated. Further embodiments show similar dampers attached to the exterior of the compressor.Type: GrantFiled: September 21, 2000Date of Patent: June 19, 2001Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Masakazu Obayashi, Naofumi Kimura, Akira Nakamoto, Kazuhiro Nomura, Hiroyuki Gennami

Patent number: 5983780Abstract: A compressor includes front and rear cylinder blocks, a drive shaft rotatably supported by the cylinder blocks, a swash plate mounted on the drive shaft, a plurality of cylinder bores defined in the cylinder blocks and located around the drive shaft, and a plurality of pistons respectively disposed in the cylinder bores. The pistons reciprocate by converting rotation of the drive shaft with the swash plate. A plurality of compression chambers are defined in the cylinder bores for compressing the gas supplied to the cylinder bores in accordance with the reciprocating movement of the pistons. Each compression chamber has dead volume defined by a space having a predetermined volume when the associated piston is at top dead center in each cylinder bore. A reference capacity is defined by the capacity when the piston is at a bottom dead center of the cylinder bore that has the smallest dead volume.Type: GrantFiled: November 18, 1996Date of Patent: November 16, 1999Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Akira Nakamoto, Kazuhiro Nomura, Takanori Okabe, Naofumi Kimura, Hayato Ikeda, Hiroyuki Gennami, Hisato Kawamura, Junichi Toyama

Patent number: 4936754Abstract: A reciprocatory piston type compressor is provided with partition walls in a discharge chamber or chambers, the walls being arranged between discharge ports open to the discharge chamber, respectively, to prevent flows of refrigerant gas discharged from the discharge ports from directly interfering with each other at least during the time in which the opening of two adjacent discharge reed valves overlap one another. The partition walls may be formed integrally with a cylinder head of the compressor in such a manner that the partition walls extend centripetally from an inner wall surface of the cylinder head defining the discharge chamber. The flows of refrigerant gas discharged from the two adjacent discharge ports which are open will not interfere with each other but will be guided independently and centripetally along the partition walls in the discharge chamber toward the tops of the partition walls, and then toward an opening that leads to an outer discharge conduit.Type: GrantFiled: November 17, 1988Date of Patent: June 26, 1990Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Shinichi Suzuki, Chuichi Kawamura, Kazuhiro Nomura
