Pressure reducing valve with separate radial bores for different fluid flow path means

摘要

The present invention relates to a hydraulic built-in valve (10) with a bushing (20) with a first longitudinal bore (24), which, by means of a front opening of a work connection point (21), in the first longitudinal bore (24) so that it can move linearly and a piston (40) is accommodated, wherein the bushing (20) in the region of a supply connection point (22) of at least one radially to the longitudinal axis (11) extending first radial bore (25) is penetrated, whereby the bush (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 passed through which, in the direction of the longitudinal axis (11) at a distance from the at least a first radial bore (25) is arranged, wherein a first fluid flow path (12) of the inlet connection point (22) to the work connection point (21), a second fluid flow path (13) of the work connection point (21) for the return connection point (23) extends.According to the invention, the piston (40) at least a third radial bore (42), which radially to the longitudinal axis (11), with it a component of the first fluid (12), with the piston (40) at least a fourth radial bore (43), which radially to the longitudinal axis (11), with it, is a component of the second fluid (13) is, it being in the direction of the longitudinal axis (11) at a distance from the at least a third radial bore (42) is arranged.
