Valve for controlling liquids

Abstract

A valve for controlling fluids is described, wherein a valve closing member (13) divides a low-pressure region (16) in the valve (1) from a high-pressure region (17), and a filling device (19) is provided to compensate for a leakage quantity from the low-pressure region (16) by withdrawal of hydraulic fluid from the high-pressure region (17). The filling device (19) is embodied in a valve body (9) with a conduitlike hollow chamber (18) in which a solid body (26) is disposed in such a way that a gap (28) is formed between the solid body (26) and the valve body (9). The material of the solid body (26) has a coefficient of thermal expansion that is so much greater than that of the material of the valve body (9) that with increasing temperature, a viscosity-dictated increase in the volumetric flow around the solid body (26) is at least partly limited (FIG. 1).
