Abstract: A pneumatically piloted retainer valve (10) for bottling brake cylinder pressure that can be set and released in response to changes in the brake pipe pressure. Pneumatically piloted retainer valve (26) provides a brake cylinder (BC) pressure retaining function that bottles applied brake cylinder pressure in the brake cylinder when brake pipe pressure is less than a predetermined cut-in pressure. Pneumatically piloted retainer valve includes a retainer valve (10) movable between a reset position, where brake cylinder pressure is in communication with exhaust and a bottle position, wherein brake cylinder pressure is isolated from exhaust. A retainer pilot control valve (40) provides for piloting of the retainer valve in response to a predetermined reduction or threshold increase in brake pipe pressure.

Abstract: A flow control device (30) having a first port (34), a second ρort (66), a third port (36) and the movable member (42). In a first mode, the movable member seals the second port while allowing fluid flow between the first and third ports, wherein the differential pressure between the first port and third port, during the first mode, is about zero. In the second mode, the movable member seals the first port while allowing fluid flow between the third port and second port, wherein the movable member is adapted to transition from the first mode to the second mode in response to a small change in differential pressure.

Abstract: A manuel vent (40) and an emergency brake valve (42) are coupled to a pipe bracket (10) such that the manual vent is in flow communication with the emergency brake valve utilizing a passageway between a service side (12) of the pipe bracket and a emergency side (14) of the pipe bracket. When the manual vent is actuated, the passageway is pressurized which resets the emergency brake valve. Once the emergency brake valve is reset, the passageway is opened to atmosphere. Accordingly, a signal is passed through a pipe bracket.

Abstract: An integrated pressure exhaust valve and pneumatic coupling is used on a truck trailer for bringing air brake pressure from a tractor to the truck trailer. A gladhand coupling moiety is used for quick connection with an identical coupling moiety on the air pressure hose from the tractor. A check valve mechanism diaphragm (33) is incorporated in the body (10) of the trailer coupling moiety for permitting air flow to the brakes when pressure from the tractor is greater than pressure in the trailer brake lines, and for permitting air flow from the brake lines to the atmosphere when pressure from the tractor is decreased. The integrated pressure exhaust valve and pneumatic couling moiety can be mounted on the front of the trailer where it is found that pressure exhaust valve placement is most effective.

Abstract: A brake cylinder limiting valve having a first portion that determines actual brake cylinder pressure and a second portion that determines intended brake cylinder pressure based on brake pipe pressure reduction. The two portions are combined so that brake cylinder pressure will be vented if the actual brake cylinder pressure exceeds intended brake cylinder pressure by a predetermined threshold amount, which is preferably two and one-half times the brake pipe pressure reduction. An exhaust cut-off valve may be used to prevent venting of the brake cylinder pressure if it falls below a predetermined value.
