摘要： A service brake inspection system engages service brake air lines downstream of a foot operated activation valve thereof to provide continuous engagement of the service brakes during inspection. The system includes a manually controlled air line which supplies air to a source port of an inversion valve. The inversion valve further includes an outlet port which is engaged to air lines supplying the vehicle service brake system via a double check valve in each of the primary and secondary service brake air lines, each being downstream of the foot operated valve. A third control port is connected to an air line disposed between a hand operated valve for exhausting the air lines to the spring parking brakes to set the parking brakes of the vehicle on. When the hand operated exhaust valve is set on, the pathway from the source to the outlet port in the inversion valve is opened to cause the service brakes to be continuously engaged for inspection.

摘要： The preferred embodiment of the invention is a brake system comprised of a primary source of air under pressure, and independent secondary source of air under pressure, a primary relay, a secondary relay valve, a device for actuating the service brakes, a device for actuating the park brakes and a control device, and a plurality of brake assemblies. The primary relay receives air under pressure only from the primary source and the secondary relay receives air under pressure only from the secondary source, but the other components are so arranges as to achieve complete system redundancy in operation at the source level, the brake level, the hose level, and at the actuation level.

摘要： An emergency and parking (E&P) brake system (6) is used with a brake system (2) of the type including an air brake coupled to a service brake actuator (8) by a slack adjustor (104) movable between brake released and brake applied positions. The E&P system includes an E&P actuator (80), located physically distant from the brake actuator, which has a variable volume spring brake chamber (82), a spring brake chamber diaphragm assembly (84) movable between first and second positions, a variable volume spring deflection compensation chamber (86), and a movable compensation chamber diaphragm assembly 88. A compression spring (90) is positioned between the two diaphragm assemblies. The spring brake chamber diaphragm assembly is connected to the slack adjustor by a flexible cable (110). The spring brake chamber is normally maintained in its first position by pressurizing the spring brake chamber. Depressurizing both chambers applies a lower, parking brake force through the cable and slack adjustor. By simultaneously pressurizing the compensation chamber and depressurizing the spring brake chamber, the compensation chamber diaphragm assembly recompresses the spring to apply a higher, emergency braking force.

A spring biasing valve piston slidably disposed in a tubular projection formed in the control piston. A spring biased slidable valve member disposed in a central bore formed in the housing and including an inlet valve cooperatively associated with an inlet valve seat formed by an annular lip of the central bore. An outlet valve seat carried by the slidable valve member and cooperatively associated with one side of the valve piston to initially close the outlet valve and subsequently open the inlet valve when control pressure is applied to the first reactive surface and for allowing the inlet valve to close when working pressure is applied to the one side of the slidable valve member to overcome the spring bias.

摘要： A vehicle air brake system includes spring set air released parking brakes to which air is supplied through a pressure holding valve which maintains the air chambers of the parking brakes at a predetermined pressure even though the air brake system may be at operating pressures substantially lower than the predetermined pressure. When the air pressure in the air brake system falls below operational levels, the pressure holding valve responds to release the air from the parking brake chambers. The pressure holding valve is operative to exhaust the parking brake chambers to substantially zero pressure, and is also operative to charge the parking brake chambers any time the input pressure is above zero and exceeds the pressure in the parking brake chambers.

摘要： A pneumatic brake system for an electrically driven vehicle having conventional service and novel parking brakes, which system integrates a service braking system, a dynamic braking system, an emergency braking system, and a parking braking system for selective and automatic application. The dynamic and service brakes are controlled by a brake application valve having a foot treadle adapted to for engagement by the vehicle operator and connected in tandum with service and dynamic braking valves so that upon initial engagement of said treadle dynamic braking is effected and upon further engagement service braking is effected. The emergency brake system is operated automatically through the use of emergency relay valves upon attainment of a predetermined air pressure within the brake system and includes a brake reapplication system which may be employed to release and then reapply the service brakes after an emergency braking conditon. The parking brake is of the spring operated, air pressure released type and is adapted for independent application by a manual control valve disposed within the parking brake line.
