Abstract
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.
Claims8
In an electro-hydraulic governor comprising
- a fixed hydro-mechanical part having electrical contact means and hydraulic circuit means,
- an external, electro-hydraulic, connections part having
- electrical circuit means for connection to the said electrical contact means of the fixed part, and
- external hydraulic circuit means for connection to the said hydraulic circuit means of said fixed part, the improvement wherein the fixed part of the governor has a plane face and further comprises an electrical connection plate including
- contact pins, and electrical connection means,
- the electrical connection plate being mounted on said plane face, and
- the external connections part comprises contact assemblies, electrical connection means, and
- a general connector, the contact pins of the fixed part being arranged to co-operate with respective said contact assemblies of the external connections part, and the electrical connection means of the external connections part serving to provide an electrical connection between the contact pins of the fixed part and the general connector, and wherein the electrical connection plate has apertures extending normally to the plane of the plate and communicating with the hydraulic circuit means of the fixed part, and capable of communication with the external hydraulic circuit means of the external electro-hydraulic connections part.
