Patent number: 7771175Abstract: A link mechanism provided between a lug plate and a cam plate in a variable displacement compressor includes a first transmitting portion for transmitting rotation of a lug plate to a cam plate and a second transmitting portion for transmitting compression reactive force from the cam plate to the lug plate, which are arranged along a rotational direction of the drive shaft. The first transmitting portion includes a first transmitting surface and a first receiving surface. The link mechanism also includes a movement restrictor arranged between the first and second transmitting portions. The movement restrictor includes a restricting surface formed in the lug plate and a restricted surface formed in the cam plate and restricts the first receiving surface to move away from the first transmitting surface in the rotational direction of the drive shaft in such a manner that the restricted surface comes into contact with the restricting surface.Type: GrantFiled: February 18, 2005Date of Patent: August 10, 2010Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Masaki Ota, Yuji Kaneshige, Motoaki Okuda, Takayuki Imai

Patent number: 6354810Abstract: A variable capacity type compressor has a swash plate, pistons reciprocating in the cylinder bores, a suction chamber, and a discharge chamber. A check valve arranged in the compressor. The check valve has a valve seat member having a flow passage and a valve seat, a case attached to the valve seat member, and a valve element arranged in the case for cooperation with the valve seat. The case has a communication hole formed therethrough to allow the gas to flow from the flow passage through the communication hole to the outside circuit. An annular groove is formed in the outer peripheral surface of the valve element to allow a leaking gas to flow from the clearance space between the valve element and the valve housing to the exterior of the valve housing.Type: GrantFiled: May 31, 2000Date of Patent: March 12, 2002Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Kazuhiko Minami, Takeshi Imanishi, Hiroaki Kayukawa, Kazuya Kimura, Yuji Kaneshige

Patent number: 6244159Abstract: A compressor includes swash plate, which is tiltably supported by a drive shaft. The displacement of the compressor changes in accordance with the inclination angle of the swash plate. The minimum inclination angle (&thgr;min) of the swash plate is less than three to five degrees relative to a plane perpendicular to the axis of the drive shaft. The swash plate can be moved from its minimum inclination to increase its angle, despite the small minimum inclination angle, due to a return spring, which urges the swash plate to increase the inclination angle. The return spring positively moves the swash plate in a direction increasing the inclination angle.Type: GrantFiled: April 9, 1999Date of Patent: June 12, 2001Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Kazuya Kimura, Yuji Kaneshige, Hideki Mizutani

Patent number: 6062824Abstract: A displacement control valve included in a variable displacement compressor. The compressor includes a fluid passage for connecting a crank chamber to a discharge chamber. The control valve includes a valve chamber connected to the crank chamber through the fluid passage, a valve hole connected to the discharge chamber through the fluid passage, and a valve body located in the valve chamber. A bellows influences the valve body through a pressure sensitive rod in accordance with suction pressure. A solenoid includes a fixed iron core and a plunger arranged in a plunger chamber. The plunger urges the valve body through a solenoid rod by a force determined by the level of electric current supplied to the solenoid. The fixed iron core, which is located between the valve chamber and the plunger chamber, includes a guide hole for receiving the solenoid rod. An annular passage for connecting the valve chamber to the plunger chamber is formed between the guide hole and the solenoid rod.Type: GrantFiled: April 26, 1999Date of Patent: May 16, 2000Assignees: Kabushiki Kaisha Toyoda Jidoshokki Seisakusho, NOK CorporationInventors: Kazuya Kimura, Kiyohiro Yamada, Yuji Kaneshige, Ichiro Hirata, Shuji Fukunaga, Kouji Watanabe, Norio Uemura

Patent number: 5845560Abstract: It is an object of the present invention to reduce the abrasion at a pressure receiving portion of the cylinder block, without increasing the manufacturing cost, even when the outer rings of a bearing are jointly rotated and eccentrically fluctuated. The cylinder blocks are made of aluminum alloy comprising, by weight, 1.5 to 3.5% of Cu, 13 to 16% of Si, 0.5% or less of Mg, 1.0% or less of Zn, 1.0% or less of Fe and the remainder of Al. The matrix, except for primary Si crystal, is relatively soft. Primary Si crystals which each independently project from the pressure receiving portions tend to be pushed into the base material by the outer rings of the thrust bearings, so that the levels of primary Si crystals are easily made to be approximately uniform.Type: GrantFiled: September 9, 1997Date of Patent: December 8, 1998Assignees: Kabushiki Kaisha Toyoda Jidoshokki Seisakusho, Showa Denko K.K.Inventors: Hiromi Nagata, Yuji Kaneshige, Masaaki Nishimoto, Hayato Ikeda, Nobuhiro Ishizaka

Patent number: 5630355Abstract: It is an object of the present invention to secure excellent slidability between a piston and cylinder bore even under severe running conditions.Cylinder blocks are made of aluminum alloy comprising, by weight, 1.5 to 5.0% of Cu, 13 to 16% of Si, 0.5% or less of Mg, 1.0% or less of Zn, 1.0% or less of Fe, and the remainder of Al, and exfoliated recessions of primary Si crystal exist on the inner surface of a cylinder bore. The large number of minute exfoliated recessions function as oil reservoir spots.Type: GrantFiled: December 29, 1995Date of Patent: May 20, 1997Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Hayato Ikeda, Hiromi Nagata, Yuji Kaneshige, Masaaki Nishimoto

Patent number: 5596920Abstract: A compressor includes a drive shaft rotatably supported on cylinder block. A swash plate rotates in accordance with rotation of the drive shaft. A plurality of pistons reciprocate in the associated bores in the cylinder block in accordance with the rotation of the swash plate. First an second thrust bearings are provided in the cylinder block at both sides of the swash plate, and receive the axial loads applied to the swash plate and drive shaft according to the reciprocation of the pistons. The first thrust bearing has the first seat portion clamped at both sides by the swash plate and cylinder block and the second seat portion located apart from one of the swash plate and cylinder block.Type: GrantFiled: April 5, 1995Date of Patent: January 28, 1997Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Satoshi Umemura, Hisato Kawamura, Toshiyuki Mizuno, Michelle Alberda, Hayato Ikeda, Tomoji Tarutani, Keishi Nakagaki, Yasunori Ueda, Hideo Mori, Kazuya Kimura, Yuji Kaneshige, Hirofumi Sato

Patent number: 5379799Abstract: A discharge valve apparatus for a compressor includes a valve plate with a port opened, a lead valve fixed on the valve plate, adapted for swingably opening and closing the port elastically, and including a substantially disk-shaped head portion and a neck portion constricted continuously from the head portion, and a retainer fixed on the valve plate, and including an inclining surface adapted for regulating the opening degree of the lead valve, the inclining surface having an inclination varying around an area where the retainer is brought into contact with the head portion of the lead valve when the lead valve fully opens the port. With the discharge valve apparatus, the lead valve can be inhibited from adhering on the retainer through the lubricant contained in the refrigerant, and accordingly the volumetric efficiency deterioration, resulting from the retardation of the lead valve in the returning, can be inhibited.Type: GrantFiled: October 22, 1993Date of Patent: January 10, 1995Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Katsunori Kawai, Ryo Kato, Akio Saiki, Yuji Kaneshige
