Control valve of the pressure of the clutch for a friction clutch of the start, a hydraulic control, in particular for motor vehicle, 2004.

摘要

The invention relates to the control of a friction clutch, 2004. / p & & p & the valve comprises a slide which is housed in a bore, and comprises two flanges 6, 7, whose end is loaded by a compression spring linear and by a pressure signal a function of the diet of the engine, and n4 the pressure of the clutch, by controlling an output located between its two collars. The second linear end of the compression spring 8 bears on a piston 9 mounted on the other side of the technical set-up has three diameters 2, 3, 4. This piston is charged, a dimension, by the pressure signal ppitot which is a function of the diet of the motor and, on the other side, by a compression spring which is not linear 11 which bears against a shoulder 12 of the bore 2, 3, 4 of the distributor.
