Abstract

A valve which ensures a constant quantity of flow regardless of the differential pressure across the valve in the working range includes a closure member (16) adjustable relative to a valve seat (22) by a electromagnetic positioning drive acting on a hollow push-rod (20) against the force of a return spring. A cavity (30) which is surrounded by a bellows (28) and which is connected to the outlet side of the seal through a radial equalizing bore (32) in the hollow push-rod (20) serves for the static equalization of the differential pressure prevailing across the valve. Both the opening of the valve seat (22) and the closure member (16) are widened out in a taper in the direction of flow in such a manner that the annular space formed between them has a substantially constant cross- section in the direction of flow when the valve is open. The approach-flow side of the valve seat (22) is constructed in the form of an inlet nozzle. The closure member (16) comprising a disc, opens in the direction of flow. The effective restrictor between the closure member (16) and the valve seat (22) has a larger diameter than the narrowest region of the valve seat (22). <IMAGE>
