John M Cassidy is a notable inventor based in Farmington Hills, MI (US). He has made significant contributions to the field of vehicle brake systems, holding a total of 2 patents. His work focuses on enhancing the safety and efficiency of braking systems in vehicles.

Latest Patents

Cassidy's latest patents include a "Fluid accumulator for use in a vehicle anti-lock brake system" and a "Hydraulic control unit with fluid compensator to accommodate travel of master cylinder piston." The first patent describes a hydraulic control unit (HCU) that features an accumulator mounted within the HCU body. This design includes a grommet for mounting the HCU body to a vehicle body, which also serves to resiliently separate the HCU body from the vehicle body. The grommet defines a vent path for the accumulator and incorporates a hollow cylindrical shaft with a closed end and an open end. The axial bore of the annular head is in fluid communication with the hollow shaft, and the design includes radially extending grooves for improved fluid dynamics.

The second patent introduces a fluid compensator within a hydraulic control unit of a vehicular brake system. This fluid compensator allows for additional displacement of a master cylinder piston during anti-lock braking events by storing fluid in the hydraulic control unit. This innovation prevents premature seal failure by moving a seal mounted on the master cylinder piston away from a compensator port orifice during braking events.
