Abstract: A fluid control valve actuated by differential pressure across a diaphragm member. The diaphragm member is secured to a piston mounted thereon with a seal ring. The seal ring is in fluid-tight sliding engagement with a casing having an inlet port and an outlet port, but is brought into disengagement from the casing upon movement of the piston due to differential pressure across the diaphragm member. Thus, communication between the inlet and the outlet ports may be accomplished.

Abstract: A vacuum actuator for connection to a vacuum source, the actuator utilizing a diaphragm combination having three stable positions. An annular diaphragm, having its outer periphery fixed in a housing, has its inner periphery secured between two movable annular members, the diaphragm and the annular members forming a combination dividing the housing into upper and lower chambers. Two inlet ports individually supply a vacuum force or atmospheric pressure to the upper chamber, the first one of the ports including a projection extending toward a space formed by the movable members. A poppet valve normally closes an opening at the top of the space, the bottom of the space normally having access to the atmosphere. When vacuum is applied to the first port, the diaphragm combination is raised from a biased first position to the position where the poppet valve interrupts the vacuum through the projection, determining the second position. The application of vacuum force to the second inlet port then raises the diaphragm combination to the third stable position, the projection sliding the poppet valve to a lower position in the space formed by the movable members, closing the access to the atmosphere.

Abstract: 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.

Abstract translation: 根据本发明的可变气门正时控制器包括用于将叶片保持在压力室的中间直到内燃机启动的锁定机构; 以及用于密封推进室和延迟室中的一个并用于减慢旋转轴和旋转传递构件之间的相对旋转的阻尼器。 根据本发明，锁定机构将叶片保持在压力室的中间，直到内燃机启动为止。 因此，即使向压力室供给不稳定的过渡压力，叶片也不会振动，从而不会产生不良的噪音。 此外，由于叶片保持在压力室的中间，所以在内燃机起动之后，气门正时可能进一步延迟。 因此，不仅可以始终优化气门正时，而且可以使发动机起动方便，也可以内燃机的高速运转。 因此，能够通过内燃机的高速运转时的进气口的惯性来提高容积效率。
