Abstract

Provided is a variable-capacity compressor control valve that can suppress a decrease in the efficiency by reducing the amount of leakage in the valve without requiring severe accuracy of the components, avoid possible operation failures, and suppress the influence on the sliding resistance as well as the influence on the control characteristics. A main valve element of a valve element or a valve body is provided with a flexible or elastic sealing member. The sealing member is adapted to, when the valve orifice is closed by the main valve element, abut an end portion on the higher pressure side in a gap between sliding surfaces that is formed between the main valve element and a guide hole into which the main valve element is adapted to be slidably fitted and inserted, and thus seal the gap between the sliding surfaces.
