Abstract:
Delivery control device, intended to allow control of the supply of various hydraulic apparatuses to achieve activation of these individually or in various combinations, characterized by the fact that it includes a pair of shutter plates, one fixed and one moveable, in which the fixed shutter plate offers several peripheral delivery passage apertures, each of which has essentially the form of a sector of a circle, while the moveable shutter plate offers a single peripheral delivery passage aperture, of a form essentially corresponding to that of one of the delivery passage apertures of the fixed shutter plate and, in a position at least approximately diametrically opposed to this single delivery passage aperture, a collective delivery passage aperture of a form essentially corresponding to the whole form of two or more delivery passage apertures adjacent to the fixed shutter plate.
