Abstract: A pressure-holding valve for a brake system having a body with a blind bore therein. The body has a first passage which connects the blind bore with a variable pressure inlet port and a pressure outlet port. The blind bore is closed by seals carried on a plug having an axial passage therein connecting said inlet port with a second passage connected to the first passage. A non-return valve is located in said blind bore between the plug and the bottom of the blind bore while a valve controlled by an electromagnet is locate in the plug. In response to an operational signal the valve controlled by the electromagnet is moved into engagement with a seat to interrupt communication between the inlet port and the first passage. If the pressure holding valve is on an incline plane, the non-return valve moves to close the axial passage to prevent the return of pressurised fluid from the outlet port toward the inlet port and thereby maintain the fluid pressure in the system at a value of the fluid pressure at the outlet port to sustain a brake application.

Abstract: A hydraulically controlled brake system for a motor vehicle, comprising a master cylinder, a corrector intended for reducing the pressure prevailing in the rear-wheel brakes in relation to that prevailing in the front wheels, and a wheel anti-lock device. The corrector is of the type with a controlled shift of the cut-off point. During the operation of the anti-lock device, the cut-off point has a specific value higher than that of a corrector equipping the vehicle without a wheel anti-lock device, while it is substantially equal to the latter in the event of a failure of the device.

Abstract: A hydraulic valve having a housing with a piston located in a bore. The piston has a passage which connects an inlet chamber with an outlet chamber. A piston responds to a pressure differential between the inlet chamber and outlet chamber pressure and an outlet pressure by moving in the bore. A valve carried by the piston engages a needle to open communication through the passage and communicate fluid from the inlet chamber toward the outlet chamber. The needle extends from a core of an electromagnet, which responds to move the valve off a seat and open communication through the passage in opposition to a spring which urges the valve toward the seat and correspondingly control communication through the passage.

A housing wall separates the internal cavity into a first chamber and a second chamber with an opening formed in the housing wall, wherein it is desirable to extend a component through the opening. A tube has an end secured in the opening in the housing wall. The tube's end includes a radially directed wall extending from the end of the tube that extends to an axially extending wall positioned concentrically with the tube and terminating with an outwardly turned segment. The axially extending wall is positioned within the opening in the housing wall with a seal positioned between the axially extending wall and the housing wall wherein the distance between the front housing section and the rear housing section is minimized, by extending the component through the tube.

Abstract: A boosted braking device for a motor vehicle having a master cylinder (200) and a pneumatic booster (100). The pneumatic booster (100) is capable of being operated by an operating rod (28) controlling the opening of a valve (26) in order to actuate a main hydraulic piston (34) in the master cylinder (200). The booster (100) has a rigid casing (10) divided in a leaktight fashion into first (12) and second (14) chambers by a moving partition (16) capable of driving a pneumatic piston (22) which can move relative to the casing (10). The main hydraulic piston (34) includes a hollow moving cylinder (38) having a secondary piston (40) which slides in a leaktight fashion in the interior thereof. The moving partition (16) is held fast to the moving cylinder (38) and is slidingly mounted on the pneumatic piston (22) so as to slide relative to the moving cylinder (38) in a forward direction over an axial distance (L) from an initial position of abutment against the rear of the pneumatic piston to a final position in which the moving cylinder (38) abuts the secondary piston (40). An annular piston (70) is held fast to the main hydraulic piston (34) when the travel of the annular piston (70) in bore (62,64) is less than the axial distance (L) while the annular piston (70) is capable of sliding over the main hydraulic piston (34) when the travel of the annular piston (70) in the bore (62,64) is greater than the axial distance (L) to obtain the maximum development of braking forces.
