A hydraulic differential locking device according the invention has a changeable range of sensitivity, the regulating slide valve being able to move even in the relieving connected position of the differential locking device, and is provided with springs ensuring the optionally selectable sensitivity of the differential locking device, the springs bearing on the two endfaces of the regulating slide valve and on the inner surface of the housing of the regulating slide valve.

Hydraulic differential locking device with adjustable sensitivity

A hydraulic flow divider and integrator for operating a plurality of hydraulic loads, in which a plurality of slide valves are each connected between a respective load and a source of pressurized fluid and subjected to hydraulic pressure bias from opposite ends by respective regulating spaces at the opposite ends of each slide valve, the slide valves each having an inlet communicating with the source, and a respective throttle connected between each inlet and a respective one of the regulating spaces of a respective slide valve and functioning to bias the respective slide valve in a valve opening direction, with hydraulic lines communicating between each one of the regulating spaces and the other regulating space of another of the slide valves, whereby a tendency to open one of the slide valves results in a reciprocal tendency to close the other slide valves, and another pressure source independent of the slide valves for pressurizing the one of the regulating spaces of at least one of the slide valves for locking same in an open state.

Hydraulic flow divider/integrator with regulating slide valves with

The invention relates to hydraulic flow dividing and integrating equipment, having a regulating slide valve in its flow path and calibrated throttlings in an admission channel of the flow path. The calibrated throttlings are adjustable as a function of entering liquid flow. Mobile rings are arranged on the regulating slide valve. With these simple technical arrangements, the field of application of hydraulic systems, e.g. for gear synchronization, is considerably enlarged.
