The invention relates to an overpressure valve (1), which is used in particular in hydraulic tension systems of traction drives. The overpressure valve (1) comprises a housing (2), which is designed as extensively pot-like, wherein a floor (9) encloses a central opening (10), which forms a valve seat (8). To form a plate valve, a closing body (7) designed as disk-like is provided, which presses against the valve seat (8) via spring means (5) by the application of force in the closed state. To form a stroke limit "S" for the closing body (7), a guide sleeve (4), which encloses the spring means (5), is provided in the housing (2), the closing body (7) being supported on the guide sleeve on the front face thereof upon reaching a maximum stroke. |
