Fluid distributing devices, particularly for hydraulic remote control

A fluid distributing device particularly for remote control comprising at least one calibration modifiable pressure reducer mounted in a body and a control member, such as a lever, capable of modifying the calibration of the reducer, which reducer comprises a plunger movable in a cavity of the body, this cavity comprising, on one side, a housing in which are placed the reducer calibrating means, this housing being connected to a low-pressure fluid zone and, on the other side, a bore in which an active part of the plunger can be moved, this active part controlling the pressure of the fluid at an outlet aperture located in the axial extension of the bore, said active part comprising a blind axial hole opening into the bore on the side of said aperture, and at least a transverse aperture provided, in the vicinity of the bottom of the blind hole, to communicate this hole with the outside surface of the active part, the transverse aperture being able to cooperate with a shoulder of the bore, which comprises, particularly, at the shoulder, precision machined surfaces for cooperating with the plunger, the part of the cavity of the distributor body located, with respect to this shoulder, on the side opposite the outlet aperture communicating with the low-pressure fluid zone, whereas the part of the bore located, with respect to the shoulder, on the side of the outlet aperture comprises a groove connected to a central pressurised fluid inlet, characterised by the fact that the body of the distributor is formed from two parts, independent of each other and connected by assembly means, these two parts being separated by a surface transversely directed in relation to the bore, this separation surface passing through the housing connected to the low-pressure zone and being located, in relation to said shoulder, on the side opposite the outlet aperture, said surface being, furthermore, located in the vicinity of one end of said bore so that before assembly of the two parts access to the bore is easy, particularly for machining operations on surfaces of this bore.
