IPC: F04B53/10
Filed: 1990-05-15
Abstract: PURPOSE:To prevent generation of impulsive sound accompanied with movement of vibrationproof member by insertedly fitting an annular member to the small diameter part of a valve body sliding in the valve hole of a relief valve, arranging a vibrationproof member between one side of the annular member and the valve body, and pressing the other side with a spring. CONSTITUTION:At relieving pressure oil, relieved oil is relieved to the suction side through a relief hole 40, a communicating passage 41, the end chamber 31a of a valve hole 31, and a communicating passage 42. Hence air mixed with oil in the valve hole 31 at assembling the relief valve is pushed out from the valve hole 31 by relief action. By pressure of relieved pressure oil, a valve body 35 is slided in the valve hole 31 against the energizated force of a spring 38. At this time, the spring 38 presses a vibrationproof ring member 36 against the valve body 35 through an annular member 48 so as not to generate side clearance on both sides of the vibrationproof ring member 36. Consequently even at movement of the valve body 35, the vibrationproof ring member 36 is not moved against the valve body 35, and generation of impulsive sound can be prevented.

Abstract: PURPOSE:To obtain a high-speed and high-precision PWM circuit by employing a synchronous PWM system and an asynchronous PWM system in hierachical combination and making the most of the advantages of the both. CONSTITUTION:A synchronous PWM circuit 3 generates a pulse SYP with width synchronizing with a reference clock 2 according to contents of high-order digit data inputs D3 and D2.

Both pulses SYP and NSP are put together by a pulse width composing circuit 5, which outputs a pulse SN with pulse width corresponding to the input data group 1 (D3 and D2, and D1 and D0). Thus, the advantages of both the synchronous and asynchronous PWM systems are utilized to obtain the high-speed and high-precision PWM circuit.
