Abstract
The invention relates to automatic braking device for a vehicle equipped with at least one fluid circuit connecting a master cylinder (10) to an application circuit including at least one brake motor (22) and comprising in addition a pump (30) capable of supplying to said application circuit via a non-return valve (31) fluid under high pressure taken from a low pressure reservoir (28). The device comprises, in combination, a proportional electrovalve connected to the application circuit and possessing of a regulating outlet (20), this electrovalve, at rest, closing a communication between the reservoir (28) and the feed entrance of the pump (30) and, when operating, opening this communication and regulating the pressure of the fluid in the application circuit and a comparison slide valve (16) which, when the pressure of the fluid in the master cylinder (10) is greater than or equal to that of the fluid in the application circuit, opens a communication between the master cylinder (10) and the application circuit and closes a communication between the regulating outlet (20) of the electrovalve and the reservoir (28), whereas it does the opposite in the opposite case.
