Latest Patents

Joseph H. Cox 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 and a slave cylinder. The design ensures that the fluid volume displaced at the rod end of the master cylinder is equal to the volume displaced at the piston side of the slave cylinder. The hydraulic circuit incorporates an automatic leveling valve assembly that opens when the lift reaches a fully lowered position, allowing for the automatic equalization of the displaced fluid volume. This innovation ensures that the lift is re-leveled each time it is fully lowered. Additionally, a sequence valve pre-pressurizes the slave cylinder before raising, compensating for any air in the circuit and fluid compressibility. A pilot-operated check valve is included to halt the descent of the lift if an obstruction is detected. Velocity sensor fuses connected to cylinder ports lock the cylinders in aligned positions in the event of a hydraulic leak.
