ABSTRACT:
Switching valve (1') with hydraulic self-holding properties, in which a s piston (11') having a closure piston element (15) connects or locks a pressure inlet (16') and a pressure outlet (17'), in which a pressure line (18, 19) leading to the pressure inlet (16') and continued to a consuming point (A), and a duct (21) leading from the pressure line to a control chamber (10) of a control piston element (12), are provided; and in which an overflow connection and a relief duct (34), openable as a function of the stroke from the annular chamber (25), are provided between the pressure inlet (16') and the annular chamber (25). The overflow connection is formed by a continuously open duct (32'), whose passage cross-section is smaller than the passage cross-section of the relief duct (34).
