Further, when a urea solution is injected, the urea solution injection pipe is straightened by flow pressure of the urea solution such that the float is forced to be immersed in the urea solution in the urea tank, and accordingly the urea solution injection valve is immersed therein. Thus, the urea solution can be efficiently injected into the urea tank.

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).
