Michael P. Weirich is an accomplished inventor based in Clinton, MI (US). He has made significant contributions to the field of hydrostatic transmissions, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

Weirich's latest patents include a hydraulic fluid system and a dump valve mechanism for a hydrostatic transaxle. The hydraulic fluid system features a plate-like dump valve that is strategically positioned between the transaxle housing and a fluid conduit connecting the pump and motor. This design allows the dump valve to relieve pressure effectively by unseating valves in the conduit. Additionally, the system incorporates a settling chamber with protrusions that trap particulates suspended in the hydraulic fluid, along with a magnet to attract and hold magnetic debris. The double lip, W-shaped seal on the output shaft ensures that hydraulic fluid and particulates do not mix between the transmission and gearing chambers. The hydrostatic transaxle itself includes a hydrostatic transmission with a pump and motor, designed to enhance efficiency and performance.
