Title: Compensating circuit for pressure converter
Inventor: KATOU KAZUYUKI
IPC: G01D5/18
Filed: 1983-02-21
Abstract: PURPOSE:To compensate for power-source-voltage depending characteristics of an output voltage of a pressure converter having a strain gage bridge circuit, by superimposing an offset voltage of an operation amplifier with respect to an output voltage of a strain gage bridge. CONSTITUTION:The resistance value of a variable resistor R7 is changed so that deviation from a proportional relationship, which is the deviation of an output voltage to the positive side with respect to a power source voltage Vc, is compensated. Thus the offset voltage of an operation amplifier OP1 is set at an appropriate value. The offset voltage component, which causes the deviation to the negative side from the proportional relationship with respect to the power source voltage when the power source voltage is increased, is superimposed on the output voltage component of a strain gage bridge. Thus the power-source-voltage characteristics of the strain gage bridge FB and the operation amplifier OP1 are correctly cancelled each other out.

The lubricating oil is fed to ring oil grooves 18 and 19, and 21 and 22 through an oil path 20, and oil paths 23, 24, 25 and is then supplied to a gap e between the axial end surfaces 9a, 9b of an inner rotor 9 and wall surfaces 1a, 3a at a housing side 4 sliding and coming in contact with the axial end surfaces. The supplied lubricating oil acts on the end surfaces of the inner rotor and an outer rotor to support the end surfaces of the inner rotor and the outer rotor for axial balance. An oil film lubricates the gap e to prevent the slide and contact surfaces from abrasion. The oil film also covers the gap e. Thus the compressed refrigerant is prevented from being leaked from the discharge side to the inlet side to enhance the efficiency of a compressor.
