Publication number: 20230035386Abstract: 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.Type: ApplicationFiled: August 8, 2022Publication date: February 2, 2023Applicant: NEW YORK AIR BRAKE, LLCInventors: Bryan M.

Publication number: 20110006595Abstract: 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.Type: ApplicationFiled: July 13, 2009Publication date: January 13, 2011Applicant: NEW YORK AIR BRAKE CORPORATIONInventors: LAWRENCE E.

Patent number: 6648424Abstract: A load sensing system for a rail car brake system, including at least two load sensing devices connected in series. The first load sensing device receives a brake signal from the brake control valve and provides a first braking signal for loads above a first value. It provides a second braking signal less than the first braking signal for loads below the first load value. The second load sensing device receives the first and second braking signals from a first load sensing device. It provides a third braking signal to the brake cylinder for loads above the second value and different from the first value and a fourth braking signal less than the third braking signal for loads below the second value.
