Abstract: A pressure sensor module for use in conjunction with an electropneumatic brake, comprising a casing and a plurality of pneumatic input ports on a first face of the casing. Transducers are inside the casing and in communication with its own port. A common electrical connector is positioned on a second face of the casing, and each of the transducers is connected, interior the casing, to the common electrical connector.

Abstract: The present disclosure relates to a pump system for parking brakes for a rail vehicle. The pump system includes at least one actuator, at least one pump and a reservoir as a fluid source. Also included is a manifold in fluid communication with the reservoir and the actuator. Further included are a plurality of valves and fluid paths internal to the manifold to allow fluid flow among the at least one pump and the reservoir.

Abstract: The present invention is a parking brake for a rail vehicle having a brake cylinder and a piston in the brake cylinder responsive to forces to apply and release the brakes on the vehicle. The parking brake further includes at least one off-center connecting rod extending though an opening in the brake cylinder and connected to the piston through that opening. The parking brake also includes a force multiplier supported by the brake cylinder and connected to the at least one off-center connecting rod. Further included is an actuator connected to the force multiplier for driving the force multiplier to provide the force to move the at least one rod and the piston to move the brakes to an apply position.

Abstract: A junction box for a trainline including a housing having a lid and a body with a first non-circular opening in a first side wall of the body. An electrical connector extends through the opening, and a portion of the exterior surface of the connector has a non-circular shape and forms a non-rotational fit with the first opening. A flange of the connector is mounted to the exterior surface of the first wall and seals the first opening. The connector includes an electrical receptacle having a first portion of the exterior surface of the connector and a threaded second portion of the exterior surface of the connector. A gasket is positioned between the flange and the first wall encompassed in the first opening. The first non-circular opening may be generally triangular.

Abstract: A car control device includes a pneumatic manifold with a plurality of fluid ports integrally formed in a housing. The configuration of the manifold and ports enables fluid communication with a brake valve, and a control valve module. The car control device also includes a functional control module in electric communication with a power management module, the control valve module, and the network. Each of the power management module, and the control valve module, the functional control module, and a battery assembly are all positioned to separately accessible within a housing.

Abstract: A vent valve made from a standard emergency brake valve portion. It includes an emergency portion body with an interface to be mated with the emergency portion interface of the pipe bracket. The body includes a casting with at least one cover and the casting including all the cast cavities and passages for an emergency portion. A vent valve selectively connects a first brake pipe port to a vent port on the body, A vent piston controls the vent valve and a discharge valve pneumatically controls the vent piston. An emergency piston is responsive to brake pipe pressure for controlling the discharge valve. The body does not include at least one of an in shot valve and an accelerated application valve.

Abstract: An electropneumatic brake controller of the present invention including a main reservoir, pneumatic brake pipe relay and first and second restrictions connected in series with the main reservoir, the brake pipe relay and brake pipe and first electropneumatic valve connected in parallel to the second restriction. The second restriction is smaller than the first restriction. The first electropneumatic valve is responsive to an electric release signal to cut out the second restriction. When the two restrictions are in series, this is the running mode whereas when the second restriction is cut out, this is the release mode. A control unit controls the electropneumatic valves to produce an overcharge cycle in response to a release brake signal. This cycle includes overcharging the brake pipe, holding the overcharged condition for a fixed period of time and bleeding to a normal release brake pipe pressure.
