Publication number: 20040178039Abstract: There is provided a compact one-way clutch unit that can perform connection and disconnection of power in two systems. An end portion on a side of a deep groove ball bearing portion 65 of a second one-way clutch 2 is disposed in an annular recess 67, which is provided at an end portion in an inner peripheral surface of a first inner ring 7, so that the dimension in an axial direction of a one-way clutch unit is reduced. Further, an outer peripheral diameter on a side of the deep groove ball bearing portion 65 is made smaller than that on the side of a one-way clutch portion 60 of a second outer ring 14 so as to reduce a diameter of the recess 67 and the outer peripheral diameter of the first outer ring 5 of the first one-way clutch 1.Type: ApplicationFiled: February 26, 2004Publication date: September 16, 2004Applicants: Koyo Seiko Co., Ltd., Kabushiki Kaisha Toyota JidoshokkiInventors: Takahiro Ichihara, Hajime Watanabe, Hideki Fujiwara, Minoru Mera, Taku Adaniya, Akinobu Kanai, Naoki Usui, Tomoharu Arai

Patent number: 6558133Abstract: A variable displacement compressor includes a supply passage for supplying refrigerant gas from a discharge chamber to a crank chamber and a bleed passage for bleeding the refrigerant gas from the crank chamber to a suction chamber. An oil separator is connected to a drive shaft and is located in the bleed passage. The oil separator rotates together with the drive shaft to centrifugally separate lubricant oil from the refrigerant gas that flows in the bleed passage. An oil chamber is formed in a compressor housing for receiving the separated oil. The pressure in the oil chamber is equal to or greater than the pressure in the crank chamber. The lubricant oil rapidly returns to the crank chamber through a return passage.Type: GrantFiled: November 19, 2001Date of Patent: May 6, 2003Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Tetsuhiko Fukanuma, Masahiro Kawaguchi, Hiroaki Kayukawa, Hiroshi Uneyama, Minoru Mera

Patent number: 6524079Abstract: In a variable-capacity swash-plate type compressor, which can vary the outlet capacity by controlling an inclination angle of a swash plate, the swash plate is aligned by contacting a washer (19) with a tapered surface to the swash plate (18). Thus, in a case where a compression operation is not carried out or in a case where a compression operation is carried out at a small outlet capacity regarded as zero substantially, the noises, etc., which generate between the swash plate and a driving shaft (6), are inhibited.Type: GrantFiled: April 12, 2001Date of Patent: February 25, 2003Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Kazuya Kimura, Tetsuhiko Fukanuma, Masakazu Murase, Minoru Mera, Atsuyuki Morishita, Shingo Kumazawa

Patent number: 6514049Abstract: A control valve is used in connection with a variable displacement compressor that varies the discharge capacity by controlling an inclination of a cam plate located in a crank chamber. The inclination of the cam plate is variable based on crank chamber pressure caused by refrigerant in the crank chamber. Monitor pressure is monitored at a predetermined point in a refrigerant circuit for causing a change in the crank chamber pressure and ultimately varying the discharge capacity. The control valve has a housing, an internal control valve mechanism and an external control valve mechanism. The internal control valve mechanism is located inside the valve housing and has a first valve body and a first reacting member. The first reacting member is connected to the first valve body for reacting to the monitor pressure to cause a change in the crank chamber pressure. The external control valve mechanism is located inside the valve housing and has a second valve body and a second reacting member.Type: GrantFiled: August 3, 2001Date of Patent: February 4, 2003Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Minoru Mera, Hideki Mizutani, Kazuya Kimura, Masahiro Kawaguchi, Takeshi Imanishi, Hiroaki Kayukawa

Patent number: 6425741Abstract: A variable capacity type compressor has a swash plate which can incline with respect to the drive shaft. An angle decreasing spring urges the swash plate to decrease the inclination angle and a return spring urges the swash plate to increase the inclination angle from the minimum inclination angle beyond the limit angle. The minimum inclination angle is smaller than a limit angle at which the swash plate can be assuredly returned in the direction to increase the inclination angle by a reaction force of the discharge pressure, and the angle decreasing spring balances with the return spring at an angle greater than the limit angle. A minimum spring load (F0) of the return spring is greater than 20N. A maximum spring load (F100) of the angle decreasing spring is F100(N)=(180±30)−4×(VD−120).Type: GrantFiled: July 14, 2000Date of Patent: July 30, 2002Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Minoru Mera, Kazuya Kimura, Hiroshi Uneyama

Patent number: 6206648Abstract: A compressor having a crank chamber in which a large amount of lubricating oil is constantly maintained. The compressor includes a pressurizing passage through which refrigerant gas flows from a discharge chamber to the crank chamber. A displacement control valve varies the displacement of the compressor by adjusting the flow in the pressurizing passage thereby changing the pressure in the crank chamber and altering the inclination of a swash plate. The compressor further includes a bleeding passage. An oil separator is arranged in the bleeding passage to separate lubricating oil from the refrigerant gas flowing through the bleeding passage. The oil separator and the crank chamber are connected to each other by a recovery passage, through which the separated lubricating oil is returned to the crank chamber, and a pressurizing passage. A venturi tube is employed to help transfer oil from the oil separator to the crank chamber.Type: GrantFiled: December 21, 1998Date of Patent: March 27, 2001Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Kazuya Kimura, Minoru Mera
