Title: Valve device for displacement type compressor
Inventor: KOUMURA TETSUSHI
IPC: F04B39/00
Filed: 1994-03-18
Abstract: PURPOSE:To reduce the generation of composite noise in addition to reduction of incurring of a suction pressure loss and the occurrence of excessive compression by a method wherein one of a valve seat surface and a lead valve is covered with a seal body with which the periphery of a through hole is surrounded and which is elastically bendable following the lead valve. CONSTITUTION:When, during operation of a compression, a relative differential pressure between a compression chamber 1a and a high pressure area 5 is exerted in a direction in which a lead valve 7a is closed, the lead valve 7a is bent in the centripetal direction of a through-hole 5a based on interference stepped parts P1 and P2 serving as a fulcrum. By bringing the lead valve into collision contact with the whole peripheral edge of the opening, the through-hole 5a is closed Simultaneously, a seal body 20a is also bent following bending of the lead valve 7a to closely seal the periphery of the through-hole 5a. Thereafter, when a relative differential pressure between the compression chamber 1a and the high pressure area 5 is reversed and attains an opening pressure for the lead valve 7a, a restoration reaction force from a bending posture assists opening of the lead valve 7a, whereby the instantaneous pressure wave of refrigerant gas and a vibration wave owing to a crush with an opening valve regulating surface are damped. Thus, a vibration noise obstacle is prevented from occurring.

Filed: 1982-03-26
Abstract: PURPOSE:To improve the resistance to radioactivity and electric noises, by detecting and converting the process quantity of the reactor equipment into electric signals and converting the amplified voltage into frequencies and then optical signals to transmit these signals through an optical fiber bundle. CONSTITUTION:An electric signal proportional to the process quantity detected by a detector 102 is amplified 102 through a reactor housing 2, and this voltage is converted into signals of high and low frequencies through a frequency modulator 104 and then into an optical signal through an electricity/light converter 106. This optical signal is converted into a frequency modulated wave by a photoelectric converter 110 in a control building 1 through an optical fiber cable 109. This frequency signal is demodulated by a modulator 112 to a signal equivalent to the original detector output. This demodulated signal is controlled to a voltage or current level suited to a display 116 by a display signal producer 114 and then displayed to the display 116. No superposition occurs in electric noises since the signal is transmitted with an optical cable, and furthermore no deterioration of S/N is caused despite the deterioration in transparency of the optical fiber since the level of frequency is detected.
