Title:

Load retention valve

Document Type and Number:

Japanese Patent JP6310083

Kind Code:

B2

Abstract:

A pressure retaining valve (1) has a main control piston (39) guided longitudinally displaceably in a single-piece or multiple-piece valve housing (29) and a non-return piston (43). In a pressure retaining position, a fluid-conducting connection between connection points (37a, 37b, 21) is shut off by the two pistons (39, 43). Connection point (37a) serves to feed media. Connection point (37b) discharges media. Connection point (21) leads to a hydraulic consumer. In a load-raising position, the two pistons (43) move relative to one another into a release position, in which the connection between the medium feed (37a) and the consumer is established. In a load-reducing position, the two pistons (39, 43) assume a spacing from one another such that the connection between the medium discharge (37b) and the consumer is established. A monitoring device (75) determines the individual switching positions of the pistons (39, 43) to ensure reliable functioning of the pressure retaining valve (1).
