Title: Innovations by Donald F Scherer

Introduction

Donald F Scherer is an accomplished inventor based in Redford, MI (US). He has made significant contributions to the field of mechanical and hydraulic systems, holding a total of 2 patents. His work focuses on enhancing the performance and feedback mechanisms in braking systems and fluid-operated torque devices.

Latest Patents

One of Scherer's latest patents is titled "Brake apply with improved reaction." This invention features a mechanical/hydraulic brake system that includes an operator input pedal to initiate braking and brake cooling. The brake return springs create a reaction force that provides the operator with a 'brake feel' or feedback force. The hydraulic apply forces tend to reduce this feedback force, but Scherer's design incorporates a plurality of balance pistons that are pressurized simultaneously with the hydraulic apply forces to maintain the feedback force felt by the operator undiminished.

Another notable patent is "Control apparatus for regulating engagement of a fluid operated torque." This invention presents an electronically mechanized control method for regulating the engagement rate or stroke time of a fluid-operated torque transmitting device. The flow rate is managed by a flow control device that operates in both low and high flow states. The shift is initiated with the flow control device in the high flow state, and after a variable delay time, the flow control valve is activated to the low flow state to complete the shift. This innovative approach allows for optimal overlap between the oncoming and off-going torque transmitting devices.
