Wet clutch valve arrangement

A wet clutch for mounting on a shaft having an internal shaft conduit for a hydraulic fluid, wherein the wet clutch comprises:

• a clutch hub configured to be mounted on the shaft;
• a clutch basket configured to be rotationally supported relative to shaft;
• a clutch pack operatively connecting the clutch hub and the clutch basket;
• a front part configured to be fixed relative to the shaft;
• an actuator supported by the front part and radially spaced apart from the shaft, wherein the actuator is configured to receive hydraulic fluid from the internal shaft conduit, wherein the actuator comprises a recess formed by the front part and operatively connected to the internal shaft conduit, and a piston positioned in the recess and configured to move axially relative to the shaft and to engage the clutch pack;
• and
• one or more relief valves connected to the actuator and configured to release the hydraulic fluid to prevent a rotationally-induced activation of the actuator;
• wherein the one or more relief valves are housed in the piston, each of the relief valves comprising a valve seat and a spherical valve member configured to cooperate with the valve seat, each of the valve seats being defined within the piston and positioned between the valve member and the shaft, and wherein each of the valve members is biased away from the valve seat in response to a rotation of the wet clutch.
