Abstract
A selective and proportional hydraulic remote control device including jacks which are connected to a high pressure oil circuit commutated by distributors. The distributors are remotely controlled by a low pressure circuit which is connected to a fluid emitter. The emitter causes the input flow of the low pressure circuit for the distributors to vary. Only the input to the low pressure circuit takes place from the emitter through connections, while the return to the tank takes place from the distributors through jets, the sections of which are fixed. The same distributor can be controlled from several different locations.
