The invention relates to an electro-hydraulic governor particularly for a turbo-jet engine. All of the electro-hydraulic or electro-pneumatic equipment units such as solenoid valves are arranged on a common plate face of the governor, the latter being provided with a printed circuit connection plate of which the substrate faces the plate surface. The hydraulic connections are made fluid-tight between the equipment units and the governor by means of apertures with seals therein, which apertures pass through the printed circuit plate.

Electrical and hydraulic connections assembly for an electro-hydraulic

The invention concerns a fluid distribution device of the type comprising on the one hand, a metallic body with a borehole, in the thickness of which a plurality of channels for the circulation of the fluid is provided, and on the other hand, in the bore of the body a core mobile in rotation or in translation capable of establishing communication between said channels, when the core occupies at least two predetermined positions. The body of the device is constituted by the tight and inseparable joining of at least two elements joined together by contact surfaces of an exactly complementary configuration and at least certain of the channels of the body consisting at least in part of grooves cut into at least one of the contact surfaces.
