John E Mahoney is a notable inventor based in West Bloomfield, MI (US). He has made significant contributions to the field of control valve technology, holding a total of 3 patents. His work focuses on mechanisms that enhance the efficiency and functionality of fluid-operated devices.

Latest Patents

One of Mahoney's latest patents is the "Control valve assembly with concentric spools." This innovative control valve mechanism features concentric spool valve members that can be selectively positioned to provide control pressure. This control pressure is essential for the selective actuation of fluid-operated friction torque transmitting devices, such as clutches and brakes, in power transmission systems.

Another significant patent is the "Variable capacity torque transmitter." This invention involves a fluid-operated friction torque transmitting device that includes an apply piston within a housing. The design incorporates an apply chamber with a predetermined area on one side of the piston and a compensating chamber of lesser area on the opposite side. The rotary valve member formed by the torque transmitting shaft and the inner hub portion of the housing connects the apply chamber to high fluid pressure and the opposing chamber to low fluid pressure during torque transmission.
