A railway car air brake hose support bracket has an upper portion with first and second attachment members, a lower portion and an air hose connector. The first attachment member enters into and engages a portion of an accessible compartment of an uncoupling mechanism housing below the coupler head, and the second attachment member is secured to an air brake hose support lug of the railway car coupler. The air brake hose connector engages an air brake hose assembly and suspends this hose assembly from the railway coupler at a predetermined distance above the rail bed. A method of installing the hose support bracket includes positioning the first and second attachment members, securing them in place, and attaching one or more railway brake hose units to the air hose connector, either before or after this positioning and securing of the upper portion of the bracket.

A protective cap is provided for protecting an end portion of a hydraulic hose of a hydraulic bicycle component. The protective cap is configured to be removably coupled to the end portion of the hydraulic hose. The protective cap comprises a head portion and a cord attachment portion. The cord attachment portion has a through hole for attaching a cord to the protective cap.

A combined dirt collector and cutout cock (CDC & COC) device for a rail car control to prevent unintentional re-pressurization of the control valve and rail car braking system. The device has an inlet configured for interconnection to an air supply, an outlet configured for interconnection to a control valve of a rail car, a valve moveable between a first position where an inlet is connected to an outlet and a second position where the inlet is isolated from the outlet, and a control valve vent positioned downstream of the valve and configured to open in response to the valve being moved into the second position. The valve may include a ball having a first passageway for selectively connecting and disconnecting the inlet from the outlet and a second passageway formed therethrough that is positioned to interconnect the outlet with the vent when the valve is in the second position.

Provided is a check valve installed in a bore of a modulator block having an inlet path and an outlet path to control a flow of oil in one direction, the check valve including: a valve housing provided with a path hole passing through at a central portion thereof to have an upper end and a lower end thereof open to communicate with the inlet path and the outlet path, and a flange portion protruding from a circumference of an outer surface of the valve housing such that the valve housing is fixed to the bore; a spring retainer coupled to one of the open upper and lower ends of the valve housing which is adjacent to the outlet path, and having an outlet port communicating with the outlet path; a plunger movably installed in the path hole while being elastically supported by a spring supported on the spring retainer, and configured to open or close the path hole according to an up and down movement of the plunger; and a lip seal having a lip portion interposed between the plunger and the valve housing to prevent oil from flowing backward toward the inlet path from the outlet path.

An airline couple that provide consumers a way to keep air lines connected while driving. The first airline couple includes a first airline connector extending forward, an airline clip including a planar rectangular tab that includes a pair of apertures disposed on the planar rectangular tab and a second airline connector extending back towards the airline clip, the airline clip is wrapped around the first airline connector and the second airline connector. The airline couple includes a piece of putty wrapped around each end of a first airline connector and a second airline connector, the piece of putty hardens between each end of the first airline connector and the second airline connector securing each end of the first airline connector and the second airline connector.

A hydraulic braking system includes a base, which has an oil chamber and a connecting hole communicating with each other, a seat, which is provided in the oil chamber and has a receiving space communicating with the oil chamber and the connecting hole, a check valve movably provided in the receiving space and the connecting hole, and an elastic member. When one end of a connecting pipe which is connected to a brake actuator is inserted into the connecting hole to engage the base, the check valve is pushed inward to inject the hydraulic fluid in the oil chamber into the connecting pipe; when the connecting pipe is detached from the base, the check valve is pushed by the elastic member, and therefore returns to the original position. Whereby, the hydraulic fluid is prevented from leaking out.

A hydraulic assembly has a hydraulic unit having a hydraulic unit body, in which a delivery channel is formed, the hydraulic unit body having a hydraulic unit body base, in which an inlet mouth is formed. The hydraulic assembly has a connection having a feed pipe for receiving a hydraulic fluid and an eyelet for outputting the hydraulic fluid, the eyelet delimiting an eyelet hole and having an upper eyelet sealing surface and a lower eyelet sealing surface. The hydraulic assembly has a pipe union having a hollow cylindrical body for receiving the hydraulic fluid from the eyelet and introducing the hydraulic fluid into the delivery channel and a pipe union head, an upper gasket and a lower gasket. The connection has a shoulder having a lower projection not interfering with the lower gasket. The connection is coupled in a fail-proof manner to the hydraulic unit, preventing the hydraulic unit from rotating during assembly and use.

A brake demand arbitrating device is provided comprising: a first transceiver configured to receive a first brake demand generated by a first brake pedal of a vehicle; a second transceiver configured to receive a second brake demand generated by a second brake pedal of the vehicle; a processor configured to determine which of the first brake demand and the second brake demand is greater; and a third transceiver configured to send the greater brake demand to a brake controller of the vehicle. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
