FIELD: machine construction.
SUBSTANCE: invention relates to waterworks and can be used for filling wagon tanks with water. The valve contains a four-link motion mechanism, one link which due to the case (10) with a covered outlet is fixed to the pipe (14), and the other made in the form of a throttle (2), through the beam (12) interacting with the piston placed in the body (9). The piston end interacts with a plunger (7), connected with spring (6), and fixed on one of the moving elements of four-link motion mechanism.
EFFECT: simplification of the design.
