Abstract

Disclosed is a hydraulic valve in which two 2/2-way valves that are embodied as seat valves are provided in order to implement a 3/3-way valve function, said seat valves being switchable between a blocked position and an open position. The outer seat valve is fitted with an annular rib (87) that is fixed to a housing as a valve seat and a radially exterior annular rib (86) of a tubular sleeve (32) as a sealing element, said tubular sleeve (32) being disposed in sections (44/1 and 44/2) of the central housing bore (41) so as to be movable in a pressure-tight and sliding manner. The other, inner seat valve encompasses an annular rib (72) that faces the sleeve and radially protrudes into a central region of the tubular sleeve (32) as a valve seat and a radially outward extending annular rib (73) of a rod-shaped valve member element (31) as a sealing element, said valve member element (31) being arranged in final sections of the sleeve-shaped valve member element (32) so as to be movable in a pressure-tight and sliding fashion. The inner 2/2-way valve is urged into the blocked position thereof by means of a valve spring (81) while a return spring (53) which engages on a face of the sleeve-shaped valve member element (32) and rests on a bottom part (52) that is fixed to the housing applies a force acting in the opening direction of the outer seat valve (86, 87) onto the inner 2/2-way valve. The return spring (53) and the valve spring (83) are coordinated such that the tension of the return spring (53) is always significantly less than the tension of the valve spring (81).
