Abstract: A vane pump can effectively utilize the total quantity of a working fluid delivered from a vane section. The pump can be used for fluid pressure operated equipment requiring a high flow rate, does not create torque loss due to a throttle valve, and can prevent the occurrence of cavitation caused by a shortage of suction. The vane pump pressurizes and delivers a working fluid through a vane section. A returning working fluid flowing through a return port is throttled and accelerated by a throttle valve, and a working fluid sent from a suction port is attracted by the accelerated returning working fluid so that the returning working fluid and the working fluid sent from a tank are sent into the vane section.

Abstract: A fixed capacity pump (P) sucks working oil from a reservoir (R) through a conduit (Rp) and a suction passage (1), and discharges the pressurized working oil into a discharge passage (2) connected to an actuator (A). A choke (21) is disposed in the discharge passage (2), and a flow control valve (F) recirculates a part of the working oil in the discharge passage (2) upstream of the choke (21) to the suction passage (1) according to a pressure loss generated by the choke (21). The characteristic of the choke (21) which significantly increases the flow resistance in a low temperature state makes the flow rate of the recirculated working oil increase, thereby preventing cavitation/noise from occurring in the pump (P) when operated at high speed and in a low temperature state.

Abstract: In a vane pump disposed inside a transmission case of a continuously variable transmission, a pump case (20), a pump drive shaft (8) rotatably supported by a shaft bore (9) of the pump case (20) to rotate a rotor (5), and a drain port (17), one end thereof being opened to a shaft bore (9) of the pump drive shaft (8) and the other end being opened to an outside of the pump case (20) are provided. A leaked oil flown via the drain port (17) from a pump discharge side is discharged to an outside of the pump case (20).

Abstract: A mechanism for mounting a seat belt of a center seating space of a vehicle seat which exhibits sufficient strength and reduces weight and production costs to the greatest degree is provided. Such a mechanism is provided by separating a seat into a right seating section and a left seating section at the center thereof such that each of the separated seating sections is independently slidable back and forth by means of a seat sliding rail formed of a pair of lower rails fixed to a floor side and a pair of upper rails fixed to the bottom of a seat. A base member bent at an intermediate bent portion defined by a belt mount plate portion and a rail mount connector portion is attached to a side surface of the inner upper rail at the rail connector plate portion such that the belt mount plate portion extends outward. An anchor for the seat belt of the center seating space of the seat is fixed to the top end of the belt mount plate portion of the base member.

Abstract: A first magnetic scale consisting of a plurality of non-magnetic parts are arranged axially at equidistant intervals, and a second magnetic scale consisting of a plurality of non-magnetic parts arranged axially at unequal intervals, are formed parallel to each other on a rod consisting of a magnetic material which can be displaced in the axial direction. The non-magnetic parts of the second scale are symmetrically disposed on both side of a predetermined position on the rod. First and second magnetic sensors are disposed in fixed positions facing the scales.

Abstract: A magnetic scale is formed by a plurality of non-magnetic parts arranged at equidistant intervals in all axial direction on a magnetic rod which displaces in the axial direction. The non-magnetic parts consist of first non-magnetic parts having a constant depth, and second non-magnetic parts having a different depth. A magnetic sensor which outputs a signal according to the depth and positional change of the non-magnetic parts is installed at a fixed position opposite the magnetic scale. Further provided are a mechanism for identifying a second non-magnetic part which has passed the magnetic sensor based on the output of the sensor, a memory for individually storing the absolute positions of the second non-magnetic parts, and a mechanism for calculating the displacement of the rod from the identified second non-magnetic part to its current position based oil the sensor output.
