Patent ID: 8047227

Claim:
A pressure limiting valve ( 10 ), consisting of a single piece valve holder ( 1 ) having a longitudinal axis (A 1 ), a single piece valve insert ( 2 ) connected to the valve holder ( 1 ), a single piece valve piston ( 3 ) supported slidably in the valve insert ( 2 ), a compression spring, acting upon the valve piston ( 3 ) with a pressure force acting in the closing direction, and a single piece adjusting shim ( 4 ) disposed between the valve piston ( 3 ) and the compression spring ( 5 ) such that the compression spring ( 5 ) is braced on one end on a bottom piece of the valve holder ( 1 ) and on the other on a face of the adjusting shim ( 4 ) facing away from the valve piston ( 3 ), wherein the valve holder ( 1 ) is cup-shaped and a cylindrical wall of the valve holder has at least two subregions ( 1 a, 1 b ), each with a different inside diameter (D 1 , D 2 ), and the subregions ( 1 a , 1 b ) merge with one another in steplike fashion, wherein the subregion ( 1 b ) of the valve holder ( 1 ) embraces the valve insert ( 2 ) from the outside, so that the steplike transition of the valve holder ( 1 ) formed by the different diameter regions (diameters D 1 , D 2 ) is seated on and surrounds a portion of the valve insert ( 2 ) for establishing the connection between the valve insert ( 2 ) and the valve holder ( 1 ), wherein the valve holder ( 1 ) has an outflow conduit ( 1 c ) in the cylindrical wall of the valve holder, the outflow conduit being oriented at an oblique angle with respect to the longitudinal axis (A 1 ) of the valve holder ( 1 ), and wherein the valve piston ( 3 ) has an end surface and a outer cylindrical circumferential surface, and at least one fiat place ( 3 a , 3 a . 1 , 3 a . 2 , 3 a . 3 ) is provided on the outer cylindrical circumferential surface of the valve piston ( 3 ), and wherein the flat places ( 3 a ) extend over only a portion of the length of the valve piston ( 3 ).
