Abstract:
Pressure holding and regulating valve characterized by a cylindrical valve housing ( 1 ) with an upper side ( 2 ), in which a central inlet bore ( 3 ) is provided with a diameter d 1 , and with a lower side ( 4 ), in which an inner bore ( 5 ) is, whose diameter d 2  is greater than that of the diameter of the inlet bore ( 3 ) and which forms an outlet of the pressure holding and regulating valve, a closure piston ( 8 ) with an upper part ( 9 ) whose diameter d 3  smaller than the diameter d 2  of the inner bore ( 5 ) and larger than the diameter d 1  of the inlet bore ( 3 ) is a freely movable, circular sealing disc ( 7 ) made of an elastomer between the closure piston ( 8 ) and an inner sealing surface ( 6 ) between the inner bore ( 5 ) and the inlet bore ( 3 ) on an inner side of the valve housing ( 1 ) is formed, and by a compression spring ( 12 ) which is supported in the inner bore ( 5 ) and presses trough the closure piston ( 8 ) the sealing washer ( 7 ) against the inner sealing surface ( 6 ).

Claim (Index 1):
Pressure holding and regulating valve characterized by:\n a cylindrical valve housing ( 1 ) having an upper side ( 2 ), in which a central inlet bore ( 3 ) is provided with a diameter d 1 , and with a lower side ( 4 ), in which an inner bore ( 5 ) is provided, whose diameter d 2  is greater than that of the diameter of the inlet bore ( 3 ) and which forms an outlet of the pressure holding and regulating valve, a closure piston ( 8 ) with an upper part ( 9 ) whose diameter d 3  is smaller than the diameter d 2  of the inner bore ( 5 ) and greater than the diameter d 1  of the inlet bore ( 3 ), a freely movable, circular sealing disc ( 7 ) made of an elastomer between the closure piston ( 8 ) and an inner sealing surface ( 6 ) between the inner bore ( 5 ) and the inlet bore ( 3 ) is formed on an inner side of the valve housing ( 1 ), and by a compression spring ( 12 ) which is supported in the inner bore ( 5 ) and via the V closure piston ( 8 ) presses the sealing washer ( 7 ) against the inner sealing surface ( 6 ).
