ABSTRACT:
A temperature compensated fluid metering valve has a body including a ported sleeve in which a metering element is slidable, the thermal coefficient of expansion of the sleeve and metering element being identical and different from that of the body. The sleeve is secured at one of its ends to the body and a device for detecting the position of the metering element is secured to the body at the other end of the sleeve. The dimensions of the body and the coefficients of expansion are selected so a change in temperature results in an apparent position error signal from the device, this signal repositioning the metering element to compensate for changes in specific gravity of the metered fluid as a result of the temperature change.
