Abstract
A pressure regulator is provided for adjusting a pressure in a hydraulic flow, which pressure can be at least partially regulated using a solenoid. The solenoid can adjust a position of a driver that comprises a solenoid armature, a solenoid armature rod, and a delimiting part. The solenoid armature can be arranged around a solenoid armature rod and can be axially displaceable inside a solenoid chamber in a housing. The solenoid armature rod can have one or more holes that fluidly interconnect a first chamber to a solenoid chamber of the regulator. The delimiting part can be arranged around the solenoid armature rod adjacent to the housing and be configured such that clearances between the delimiting part, the solenoid armature rod, and the housing enable a certain radial movement between the driver and the housing.
