He has made significant contributions to the field of hydraulic systems, particularly with his innovative designs that enhance the functionality and safety of hydraulic lifts. His work is recognized for its practical applications in the automotive industry.
Latest Patents
Brian holds a patent for an "Automatic Hydraulic Lift Circuit." This invention features an improved hydraulic circuit for a two-post lift, which includes a master cylinder connected to a slave cylinder. The design ensures that the fluid volume displaced at the rod end of the master cylinder is equal to that displaced at the piston side of the slave cylinder. This automatic leveling valve assembly opens when the lift reaches a fully lowered position, allowing for the equalization of fluid volume and releveling of the lift. Additionally, a sequence valve pre-pressurizes the slave cylinder before raising, addressing any air in the circuit and fluid compressibility. The design also incorporates a pilot-operated check valve that halts the descent of the lift if an obstruction is detected. Furthermore, velocity sensor fuses lock the cylinders in aligned positions in the event of a hydraulic leak.
