Hydraulic regulating device for load shifted gears

A hydraulic regulating device for a load shifted gear system, particularly for an automatic transmission system in motor vehicles, including a plurality of hydraulic coupling elements, a return conduit, and a pressure source connected to a high pressure conduit, said regulating device comprising a first pressure regulating valve operable for building up pressure according to a control signal;

• a second pressure regulating valve for decreasing pressure according to another control signal;
• and a three-way, two-position control valve combination assigned to each coupling element and including a solenoid operated directional control valve, a switch-on reversing valve connected beween the first pressure regulating valve and the directional control valve and being activated in response to a predetermined high pressure level on said assigned copling element to switch over the connection from said first pressure regulating valve to said high pressure conduit, and a switch-off reversing valve connected between said directional control valve and said second pressure regulating valve, said switch-off reversing valve being activated in response to a predetermined low pressure level on said assigned coupling element to connect said directional control valve from a return conduit to said second pressure regulating valve.
