  • Pressure-limiting valve
    Patent number: 9228667
    Abstract: A pressure-limiting valve is proposed, in particular for a common rail system. The pressure-limiting valve comprises a valve support (10), a valve insert (12) which is connected to the valve support (10), a valve piston (14) which is mounted such that it can slide in the valve insert (12), and a closing spring (16) which acts on the valve piston (14) with a closing force in the closing direction. By means of the closing force, the valve piston (14) acts on a valve seat (18) which produces a hydraulic connection via a valve chamber (40) between a high-pressure space (33) and a low-pressure space (36), as soon as the hydraulic force which acts on the valve piston (14) in the opening direction exceeds the closing force of the closing spring (16). When the valve seat (18) is closed, a leakage gap (50) is formed between the valve chamber (40) and the low-pressure space (36), which leakage gap (50) makes it possible for the leakage to be discharged out of the valve chamber (40) into the low-pressure space (36).
