Abstract
The invention relates to a system of distribution of a fluid under pressure for a driving device. The system comprises a main distributor D.sub.3 mounted on a base plate E.sub.3, and at least one auxiliary unit such as a progressive starter U.sub.1 or a drain-blocker U.sub.2, wherein the auxiliary unit U.sub.1, U.sub.2 comprises a standard distributor D.sub.1, D.sub.2, advantageously of the same type as the main distributor D.sub.3, which is mounted interchangeably on a specific base plate E.sub.1, E.sub.2 configured to determine the function of the auxiliary unit and associable with the base plate E.sub.3 of the main distributor D.sub.3 and with the base plates of other auxiliary units if any.

A modular system for the distribution of a pressure fluid connected to a pressure fluid supply system and to a driving device adapted to receive said fluid, said modular system comprising:
- at least one main unit (U.sub.3) comprising a distributor (D.sub.3) and a base plate (E.sub.3) provided with a mounting face, said base plate ensuring the connection of said distributor to said driving device and to said fluid supply system, said distributor being mounted interchangeably by means of a mounting face on said mounting face of said base plate,
- said distributor mounting face and said base plate mounting face comprising the same configuration of registering orifices of supply connectable to said fluid system, of outlet for the distribution of the pressure fluid to said driving device, of discharge and of control, said distributor being switchable between two positions for establishing predetermined connections between said distributor mounting face supply and outlet orifices,
- said base plate (E.sub.3) comprising a front and a rear connecting face provided respectively with the same configuration of two discharge orifices and one pressure fluid orifice which is an inlet orifice in the front face and an outlet orifice in the rear face, said base plate (E.sub.3) having external orifices connectable to said driving device and additionally comprising internal passageways connecting said pressure fluid inlet orifice of said front connecting face to said pressure fluid outlet orifice of said rear connecting face and to said pressure fluid supply orifice of said base plate mounting face, for connecting each one of the two discharge orifices of said front connecting face to one corresponding discharge orifice of said rear connecting face and to one corresponding discharge orifice of said base plate mounting face and for connecting each one of said outlet orifices of said base plate mounting face to said external orifices connectable to said driving device;
- at least one auxiliary unit (U.sub.1) mounted upstream in series with said main unit (U.sub.3) to constitute a progressive starter, said auxiliary unit (U.sub.1) comprising a distributor (D.sub.1) and a base plate (E.sub.1) provided with a mounting face, said distributor (D.sub.1) being mounted interchangeably by means of a mounting face on said mounting face of said auxiliary unit base plate, said auxiliary unit base plate (E.sub.1) comprising front and rear connecting faces provided for the connection of said auxiliary unit (U.sub.1) to said main unit (U.sub.3) and to said fluid supply system, said front and rear connecting faces of said auxiliary unit base plate having the same configuration of two discharge orifices and one pressure orifice which is a pressure inlet orifice in the front face and an outlet pressure orifice in the rear face, each one of said front connecting face discharge orifices being directly connected through internal passageway to a corresponding rear connecting face discharge orifice, wherein the improvement consists in that said auxiliary unit distributor (D.sub.1) is of the same type as the main unit distributor (D.sub.3), whereas the auxiliary unit base plate differs from the one of the main unit, and in that said auxiliary unit base plate mounting face comprises a first pressure fluid orifice communicating with said pressure inlet orifice of said front connecting face of said auxiliary unit base plate (E.sub.1), a second orifice and a third calibrated orifice provided with a nozzle, these two orifices communicating with the outlet pressure orifice of the rear connecting face of said auxiliary unit base plate, each of said auxiliary unit base plate mounting face orifices being in a registering relationship with an auxiliary unit distributor mounting face orifice, and said two orifices are alternately connectable through communication of said auxiliary distributor to said pressure fluid orifice of said auxiliary unit base plate mounting face, the auxiliary unit distributor mounting face orifices without registering auxiliary unit base plate mounting face orifice being obturated by said auxiliary unit base plate mounting face, said three orifices of said auxiliary unit base plate mounting face being so arranged that the auxiliary unit distributor (D.sub.1) connects the first orifice either to the second orifice or to the third, calibrated orifice, depending on its switching position.
