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.
