20120198992 | VOLUME CONTROL VALVE - A capacity control valve capable of enhancing the function of discharging liquid refrigerant in a control chamber during startup of a variable capacity compressor, and improving the control speed of a swash plate during control is provided. The valve has an adapter that has an annular bearing surface and is provided to a free end of a pressure-sensitive body in the elongation and constriction direction, and a valve body for discharging liquid refrigerant, moveably provided inside the adapter. A slit is provided to an engaging part of the adapter with a third valve part, and an introduction hole for causing the control chamber pressure to act on a bottom surface of the valve body for discharging the liquid refrigerant is provided to the base part side, and an urging force is provided whereby the valve body for discharging the liquid refrigerant is urged in a valve-opening direction away from the third valve part. | 08-09-2012 |
20120198993 | CAPACITY CONTROL VALVE - A capacity control valve for a variable-capacity compressor such as used in an air-conditioning system in a motor vehicle is provided, wherein foreign matter is prevented from being caught in the sliding parts and leakage on the sliding parts is prevented from occurring by configuring the capacity control valve so that there are no sliding parts between the valving element and the housing (valve body). | 08-09-2012 |
20140099214 | CAPACITY CONTROL VALVE - In a capacity control valve, a discharged-fluid-receiving part having a diameter that is larger than the diameter of a valve hole interconnecting a first valve chamber and a third valve chamber is provided to the outer periphery section of a third valve part. It is thereby possible to obtain a capacity control valve in which, when the first valve part opens, the discharged-fluid-receiving part receives the pressure of the discharged fluid, the actuation response of the valve body during an opening action is moderated, an excessive increase in the sensitivity to a rise in pressure in the crank chamber caused by a rapid increase in the amount of coolant flowing into the crank chamber is prevented, and the action of the valve body is stable. | 04-10-2014 |

20150204915 | CURRENT DETECTION STRUCTURE - A current detection structure includes a busbar to flow a current therethrough, a magnetic detection element to detect a strength of a magnetic field generated by the current flowing through the busbar, and a current detecting portion to determine the current flowing through the busbar based on the magnetic field detected by the magnetic detection element. A through-hole is formed penetrating the busbar such that a current path is formed on both sides of the through-hole. The magnetic detection element is disposed in the through-hole. The current detecting portion determines the current flowing through the busbar based on a strength of a synthetic magnetic field detected by the magnetic detection element. The synthetic magnetic field is produced by combining a magnetic field that is generated by a current flowing through the current path on the both sides of the through-hole. | 07-23-2015 |
20150204916 | ELECTRIC CURRENT SENSOR - An electric current sensor includes a plurality of bus bars arranged in parallel, a plurality of magnetic detection elements that are adapted to detect a strength of a magnetic field generated by an electric current flowing through the bus bars and to output a voltage according to the strength of the magnetic field detected, and an arithmetic operation part to arithmetically operate an electric current flowing through the bus bars based on the voltage output from the plurality of magnetic detection elements. The arithmetic operation part includes a magnetic flux density arithmetic operation part to arithmetically operate a magnetic flux density based on the voltage, and an electric current arithmetic operation part to arithmetically operate an electric current I | 07-23-2015 |
20150204919 | CURRENT DETECTION STRUCTURE - A current detection structure includes a plurality of busbars arranged in parallel, and a plurality of magnetic detection elements each provided for corresponding one of the plurality of busbars so as to measure a strength of a magnetic field generated by a current flowing through the corresponding busbar. The plurality of magnetic detection elements are mounted on a single circuit board. | 07-23-2015 |
