Abstract:
A pressure regulating valve includes a housing, control slide valve, coupling rod, armature, outlet port, and pressure transmission pin. The armature demarcates a first fluid space and a second fluid space from each other. The rod extends with a constant first outer cross-sectional shape in a direction of a longitudinal axis, and at least partially demarcates a third fluid space that fluidically connects the first fluid space to the outlet port. The pin extends with a constant second outer cross-sectional shape in the direction of the longitudinal axis, and at least partially delimits the third fluid space. The pin is positioned so that one end facing toward the armature projects into the control slide valve, and another end facing away from the armature is at least indirectly supported against the housing. A hydraulically effective area of the second shape is larger than a hydraulically effective area of the first shape.

Claim (Index 1):
A pressure regulating valve, comprising:\n a housing including:\n an inflow port; \n a return flow port; and \n an outlet port; \n a control slide valve positioned in the housing and movable along a direction of a longitudinal axis, the control slide valve and the housing together forming a first orifice and a second orifice that each have a cross-sectional area that is adjustable in opposite directions via movement of the control slide valve, wherein:\n the inflow port is fluidically connected to the outlet port via the first orifice; and \n the return flow port is fluidically connected to the outlet port via the second orifice; \n a pole tube; an armature that is positioned in the pole tube and movable along the direction of the longitudinal axis, and that demarcates a first fluid space and a second fluid space from each other within the pole tube such that the first fluid space and the second fluid space each have a volume that is adjustable in opposite directions via displacement of the armature; a coupling rod that extends with a constant first outer cross-sectional shape in the direction of the longitudinal axis, and that motionally couples the armature with the control slide valve, wherein:\n at least inner sections of the coupling rod and the control slide valve together at least partially delimit a third fluid space that extends in the direction of the longitudinal axis; and \n the third fluid space fluidically connects the first fluid space to the outlet port; and \n a pressure transmission pin that extends with a constant second outer cross-sectional shape in the direction of the longitudinal axis, and that includes:\n a first end facing toward the armature and projecting into the control slide valve; and \n a second end facing away from the armature and positioned so that the pressure transmission pin is at least indirectly supported against the housing; \n wherein a hydraulically effective area of the second outer cross-sectional shape is larger than a hydraulically effective area of the first outer cross-sectional shape.
