Abstract: A control for a hydraulic power boost assembly in a braking system. Located within a housing of the boost assembly is a control piston which has a projection extending therefrom for abutting a spool valve in a valve chamber. The spool valve is responsive to movement of a brake pedal and regulates hydraulic fluid pressure to move a power piston which activates the master cylinder which in turn supplies fluid pressure to the wheel cylinders of a vehicle. The control piston is a stepped diameter piston which has one end thereof exposed to the fluid pressure in the master cylinder and the other end thereof exposed to the fluid pressure acting on the power piston. Upon manual activation by the brake pedal, the fluid pressure from the master cylinder moves the stepped control piston into engagement with the spool valve thereby preventing it from moving until the brake pedal is released. Such an arrangement prevents sudden surges of hydraulic fluid to the power piston in the power chamber which would cause an abrupt stop of the vehicle.

Abstract: A hydraulic brake booster is connected in series flow relationship in a vehicle hydraulic system between a source of fluid pressure and other hydraulic power equipment, such as a steering gear. The booster includes a housing with a bore in communication with an inlet connected to the source and an outlet connected to the steering gear. A piston having an end exposed to a boost chamber is shiftable in the bore from a first position to a second position by control valve means slidably carried in a central passage of the piston for controlling communication between the inlet and boost chamber. A hydraulic fluid system bypass valve separate from the control valve means, is located in the housing bore between the inlet and outlet for regulating inlet pressure and maintaining uninterrupted flow to the outlet upon shifting the piston.

Abstract: A pressure limiting device is provided which prevents the output pressure from a power braking system from exceeding the brake line pressure capacity. During normal brake application the pressure limiting device does not function. If hydraulic boost pressure combined with manual operator input force become too great, and brake line pressure exceeds a predetermined value which threatens to rupture the brake line hoses, the limit device functions to prevent further system pressure buildup.

Abstract: A vessel for storing fluid under pressure includes a housing having a chamber in one end thereof into which concentric pistons of differential areas are urged by resilient means. Admission of fluid under pressure to the chamber acts on the differential areas of the pistons moving them simultaneously against the resilient means until the pressure and volume of fluid respectively, each attains a first predetermined value, at which time the pistons are held against further movement, with the piston having the larger area being held against a fixed stop and the piston having the smaller area being held by the resilient means up to a second predetermined value of chamber pressure which represents the maximum fluid working pressure of the system to which the vessel is connected. Any pressure increase in the chamber above the second predetermined value, due to fluid expansion caused by temperature increase, is effective across the differential area between the concentric pistons so that as the chamber pressure exceeds the second predetermined pressure value the piston with the smaller area will move against the resilient means to compensate for volumetric increase.

Abstract: A HYDRAULIC BOOST DEVICE IS DISCLOSED WHICH INCLUDES A HOUSING HAVING A FLUID INLET, AN OUTLET, A BORE COMMUNICATING THE INLET WITH THE OUTLET, AND A CHAMBER IN FLUID COMMUNICATION WITH THE BORE. A SPOOL VALVE IS SLIDABLE IN THE BORE FROM A POSITION IN WHICH SUBSTANTIALLY ALL OF THE FLUID FLOW INTO THE INLET IS DIRECTED TO THE OUTLET TO A POSITION IN WHICH A PORTION OF THE FLUID FLOWING INTO THE INLET IS COMMUNICATED TO THE CHAMBER THROUGH A FLUID PASSAGE IN THE VALVE MEANS. THE FLUID IN THE CHAMBER SLIDES A PISTON TO ASSIST THE VEHICLE OPERATOR IN APPLYING THE BRAKES. A CONTROL ROD WHICH IS ACTUATED BY THE VEHICLE OPERATOR WHEN THE VEHICLE''S BRAKES ARE APPLIED IS CONNECTED TO A SLEEVE THAT IS SLIDABLY MOUNTED ON THE SPOOL VALVE. A SPRING NORMALLY PREVENTS RELATIVE MOVEMENT BETWEEN THE SLEEVE AND THE SPOOL VALVE, BUT PERMITS THE SLEEVE TO MOVE RELATIVE TO THE VALVE TO CLOSE THE PASSAGES IF A MALFUNCTION PREVENTS THE SPOOL VALVE FROM MOVING. THIS FEATURE PREVENTS A SUDDEN SURGE OF FLUID FROM BEING COMMUNICATED TO THE CHAMBER DURING A MANUAL BRAKE APPLICATION.
