摘要： A hydraulic braking system for a rail car is provided. The system includes a hydraulic pump or motor adapted to engage a rail car axle or wheel. When rotating, the axle or wheel drives the hydraulic pump causing a hydraulic fluid to circulate. By restricting the flow of fluid to the pump, a braking force can be applied to the axle for slowing and stopping the rail car. Various programmable electronic controls can be added to the braking system for allowing control at a central location.

摘要： An air compressor for a railway vehicle includes a compressor housing, at least one piston cylinder supported in the compressor housing, the at least one piston cylinder including a cylinder head and a piston, a crankshaft assembly supported by the compressor housing and linked to the piston of the at least one piston cylinder, and an unloader valve positioned on the cylinder head of the at least one piston cylinder. The unloader valve may be configured to exhaust pressurized air from the at least one piston cylinder.

摘要： A pneumatically piloted retainer valve for bottling brake cylinder pressure that can be set and released in response to changes in the brake pipe pressure. Pneumatically piloted retainer valve provides a brake cylinder 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 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 provides for piloting of the retainer valve in response to a predetermined reduction or threshold increase in brake pipe pressure.
