20140169995 | ELECTRIC OIL PUMP - An electric oil pump includes an electric motor and an oil pump that is driven by the motive power from an electric motor, wherein; the oil pump has an introducing channel that guides a drain oil that has leaked from an interior of the oil pump to an interior of the electric motor; and the electric motor has a discharging channel that discharges the drain oil that has been guided to the interior of the electric motor to a tank. | 06-19-2014 |
20140294650 | VANE PUMP - A vane pump is used as a fluid pressure supply source and includes a rotor which is driven and rotated, a plurality of slits which are radially formed in the rotor, a plurality of vanes which slidably project from the slits, a cam ring with which tip parts of the vanes slide in contact as the rotor rotates, a pump chamber which is defined between the cam ring and adjacent ones of the vanes, a plurality of discharge ports which introduce working fluid discharged from the pump chamber contracting as the rotor rotates, a discharge passage which causes the working fluid introduced from the discharge ports to join, and a check valve which is opened for a flow of the working fluid discharged from one discharge port to the discharge passage. | 10-02-2014 |
20150030486 | VARIABLE CAPACITY VANE PUMP - In a variable capacity vane pump in which a discharge capacity of a pump chamber is varied by varying an amount of eccentricity of a cam ring relative to a rotor, a port inner wall surface that extends around an inner peripheral cam surface of the cam ring when the cam ring moves in a direction for increasing the amount of eccentricity of the cam ring relative to the rotor is formed on an intake port. | 01-29-2015 |
20150044083 | VARIABLE CAPACITY TYPE VANE PUMP - A variable capacity type vane pump with a first fluid pressure chamber and a second fluid pressure chamber provided at opposite sides of a pivot point of a cam ring includes a control valve for controlling a drive pressure of working fluid introduced from a pump chamber to the second fluid pressure chamber, a suction pressure of the working fluid sucked into the pump chamber is constantly introduced to the first fluid pressure chamber, and the cam ring pivots in a direction to decrease a discharge capacity due to a pressure in the pump chamber acting on an inner peripheral cam surface during an operation to reduce the drive pressure, whereas the cam ring pivots in a direction to increase the discharge capacity during an operation to increase the drive pressure. | 02-12-2015 |
20150056090 | VARIABLE CAPACITY TYPE VANE PUMP - In a variable capacity type vane pump in which a cam ring pivots, a discharge port is so formed that an absolute value of a difference between a discharge port start edge line inclination angle and a discharge port end edge line inclination angle is larger than a vane angle. | 02-26-2015 |
