摘要： A variable valve timing controller according to the present invention comprises a locking mechanism for holding the vane in the middle of the pressure chamber until the internal combustion engine starts; and a damper for sealing up one of the advance chamber and the delay chamber and for slowing the relative rotation between the rotational shaft and the rotation-transmitting member. According to the present invention, the locking mechanism maintains the vane in the middle of the pressure chamber until the internal combustion engine starts. Therefore, the vane cannot vibrate even when unstable transitional pressure is supplied to the pressure chamber so that no undesirable noise shall be generated. Further, the valve timing may be further delayed after the internal combustion engine starts since the vane is maintained in the middle of the pressure chamber. Therefore, the valve timing may be consistently optimized not only for easy engine starting but also for the high-speed operation of the internal combustion engine. Thus, the volumetric efficiency can be improved by the inertia of the air intake under high-speed operation of the internal combustion engine.

摘要： An electromagnetically operable proportional pressure control device has a spool which is slidably housed in a cylindrical bore formed in a housing. A pressure chamber defined in the cylindrical bore communicates with an inlet port through a diametrically reduced bore and an outlet port through a return hole, a pilot valve and a return passage. The pressure difference produced between the inlet port and the pressure chamber causes the spool to move establishing a direct fluid communication of both ports. An oil flow from the inlet port into the pressure chamber is smaller than an oil flow from the pressure chamber to the return passage.

A pumping chamber is defined between the outer surface of the inner rotor and the inner surface of the outer rotor between the mutually meshing teeth thereof. An aperture is formed in the pump housing to define an intake plenum, and this aperture opens to define an intake port structure through several portions of the circumferential inner wall surface of the rotor receiving cavity, at least one remaining portion of the circumferential inner wall surface of the rotor receiving cavity intervening between separate such several portions of the circumferential wall surface of the rotor receiving cavity which are removed to allow the intake port structure to open therethrough.

摘要： An electromagnetic proportional pressure control valve includes a housing having at least one fluid inlet port and fluid outlet port and a passage for communicating between the ports. A spool is slidably accommodated in the housing for opening and closing the passage between both the ports. A plunger device is housed in the housing to define a pressure chamber, and includes a pilot valve. A return passage is arranged through the plunger device between the pressure chamber and the outlet port. The opening and closing of the return passage is controlled by the pilot valve. A restricting device restricts a fluid communicating between the inlet port and the pressure chamber. An electromagnetic device has an electromagnetic coil and a core of magnetic material to generate electromagnetic force for allowing the pilot valve to move so as to control the opening and closing of the return passage. Lastly, the pressure control includes a device for preventing the pilot valve from moving as a result of fluctuations in the fluid pressure in the pressure chamber regardless of the electromagnetic force generated by the electromagnetic device.
