PRESSURE REDUCING VALVE WITH SEPARATE RADIAL BORES FOR DIFFERENT FLUID FLOW PATHS

摘要

The invention relates to a hydraulic cartridge valve (10) having a socket (20) having a first longitudinal bore (24) which forms a working connection point by means of an end-face opening (21), wherein in the first longitudinal bore (24), a piston (40) is linearly movably received , wherein the sleeve (20) in the region of an inflow junction (22) of at least one radially to the longitudinal axis (11) extending first radial bore (25) passing through it, said bushing (20) in the region of a return connection point (23) of at least one radially to the longitudinal axis (11) extending second radial bore (26) is penetrated, which in the direction of the longitudinal axis (11) spaced from the at least one first radial bore (25) is arranged, wherein a first fluid flow path (12) from the inflow junction (22) to the working connection point (21), wherein a second fluid flow path (13) of the working connection point (21) to the return connection point (23) erstr hatched.; According to the invention, the piston (40) at least a third radial bore (42), which extends radially to the longitudinal axis (11), wherein it is a component of the first fluid flow path (12), said piston (40) has at least a fourth radial bore (43) , which extends radially to the longitudinal axis (11), wherein it is a component of the second fluid flow path (13), being spaced along the longitudinal axis (11) for at least a third radial bore (42) is arranged.
