A replacement cartridge for repairing rather than replacing an angle cock. The cartridge has a ball key with a ball and a shaft. A unitary ball seat that has first and second internal bearing surfaces for engaging the ball is used to support the ball key when installed in the angle cock body that is being repaired. A cover is positioned over the ball seat and defines a bore through which the shaft of the ball key extends. A handle is coupled to the shaft of the ball key so that a user may rotate the ball between the internal bearing surfaces between an open position and a closed position.

Angle cock repair cartridge

A prolonged release system having a locking member pivotally mounted on a post within a hand brake and having an arm that contacts a clutch assembly to prevent the clutch assembly of the handbrake from engaging after it has been manually released. Rotation of the hand brake wheel causes a pawl on a ratchet gear to move into contact with a cam of the locking member so that the arm of the locking member moves out of contact with the clutch assembly. By maintaining the clutch assembly in a released position, the prolonged release system ensures that the brake chain drum is decoupled from the driveshaft of the hand brake and prevents the inadvertent application of the brakes. When a user turns the hand brake wheel, the locking member is disengaged from the clutch assembly and the hand brake can be set by a user.

Rail handbrake with prolonged release

An electrical trainline junction box formed from a housing having first and second opposing sides, an identification module positioned in the housing, and first and second receptacles positioned in each of the first and second opposing sides. The first and second receptacles have a plurality of electrical contacts arranged in a predetermined geometry so that only one possible orientation and electrical connection to trainline flanges is possible. The flanges include contact pins in inserts coupled to the flanges by sleeves. The outer surface of the inserts and the inner surface of the sleeves are keyed to allow only a single orientation of the inserts relative to the sleeves. The outer surface of the sleeves is shaped to allow only a single orientation of the sleeves relative to the flanges, thus ensuring that the proper electrical connection is made when the junction box is installed.

A brake cylinder maintaining valve may include spool valves or poppet valves. When the pressure in the brake cylinder drops below its original set pressure, such a maintaining valve may feed brake pipe (BP) pressure through a choke to replenish and maintain brake cylinder (BC) pressure up to a certain point. If the leak is too great, such as when it exceeds the capacity of the choke, the brake cylinder pressure will not be maintained. Such a maintaining valve may be either integrated into the control valve, or it may be mounted remotely to the brake system. If mounted remotely, it may be connected by multiple ways, including through a conventional 4-port access plate.

Brake cylinder maintaining valve

In a rail vehicle hand brake having a release activated by a pneumatic cylinder, the present control system includes a manual valve having an output connected to a source of pressure at an input when manually activated. A volume is to be charged by the source of pressure. A choke connects the volume to exhaust. The volume and the choke prolong the time the source of pressure is connected to the pneumatic cylinder after the manual valve is activated.

Automatic release hand brake control system

A brake cylinder maintaining valve may include spool valves or poppet valves. When the pressure in the brake cylinder drops below its original set pressure, such a maintaining valve may feed brake pipe (BP) pressure through a choke to replenish and maintain brake cylinder (BC) pressure up to a certain point. If the leak is too great (to the extent it exceeds the capacity of the choke), the brake cylinder will not be maintained. Such a maintaining valve may be either integrated into the control valve, or it may be mounted remotely to the brake system. If mounted remotely, it may be connected by multiple ways, including through a conventional 4-port access plate.

A brake system includes a brake cylinder having a piston rod and a brake lever connecting the piston rod to a brake beam and a slack adjuster. An actuating lever is connected to the brake beam and the brake cylinder. A trigger of the slack adjuster is connected to the actuating lever. The actuating lever is pivotally and rotationally connected to the brake beam and swivelably connected to the brake cylinder. Also, a piston stoke indictor including an indicia positioned on a support structure of a brake cylinder to be adjacent the end of a portion of a brake piston at its extended position.

Bolster mounted brake system

The dual vent valve includes a housing having brake pipe, emergency input and exhaust ports, and first and second valves. The emergency output port is fluidly connected to the emergency input port. The first valve selectively connects the brake pipe port to the exhaust port by opening the first valve in response to an emergency signal on the brake pipe port. The second valve selectively connects the brake pipe port to the exhaust port by opening the second valve in response to an emergency signal on the emergency input port.

Brake pipe vent valve for locomotive brake system

A hand brake control system for a rail vehicle hand brake having a release trigger. The system includes a cylinder for activating the release trigger of the hand brake and a source of pressure. A first valve selectively connects either the source of pressure at a first input or a second input to the cylinder at an output. A second valve selectively connects either the source of pressure or exhaust to the second input of the first valve at the output of the second valve. The first valve is a manually operated valve and the second valve is an electro-pneumatic valve. Linkage allows actuation of the first valve from at least two location about the vehicle.

Control system for automatic release hand brake

A hand brake actuator for a rail car has a rotary input connected to a rotary output by a transmission including a clutch and a ratchet wheel and pawl, a declutching mechanism for disengaging the clutch in a declutched position of the declutching mechanism, and a release handle with a first cam which drives the declutching mechanism to the declutched position when the release handle is moved from an apply position to a release position. A second cam is biased in a first direction to engage and retain the declutching mechanism in a declutched position after the release handle is removed from the release position. A follower is connected to the second cam and is responsive to the rotation of the input in an apply direction to rotate the second cam in a second direction opposite the first direction to release the declutching mechanism and allow the clutch to reengage.

An End of Car (EOC) junction box assembly includes a housing wherein a plurality of female/female contact sockets couple with a corresponding plurality of male contact pins and are positioned by a fitting that enables the female/female contact sockets to interface with an EOC receptacle plug also included in the housing body, such that alternate positions of the fitting and EOC receptacle plug are available during assembly while the components included in the housing body are restrained from rotation following assembly.

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.
