Abstract
A pressure-limiting valve with feed function, comprising a valve housing (20) having at least two connection points, in particular in the form of a working connection (A) and a tank connection (T), and having a spring-loaded pressure-limiting valve piston (22) which is mounted such as to be longitudinally movable in the valve housing (20), and having a spring-loaded non-return valve piston (56) for the implementation of the feed function, is characterized in that the non-return valve piston (56) is designed as a hollow piston and is mounted such as to be longitudinally movable in the valve housing (20).
