UNIVERSAL DIFFERENTIAL Russian patent published in 2018 - IPC F16H48/27 

FIELD: machine building.

SUBSTANCE: invention relates to differential mechanisms with locking devices. In the universal differential, the locking device is composed of the reversible hydropump with a stator, rotor, vanes with springs, distribution disc, cover, check valves, suction, delivery and discharge channels. Locking device has two differential lock valves installed after the check valves in the axial parts of the output channels. Each valve consists of a piston with axial grooves of a trapezoidal section located on its lateral cylindrical surface along its height at the same distance, and a return compression spring installed in the coaxial hole following the hole for the piston.

EFFECT: blocking properties of differential is increased.
