摘要： A spring-loaded brake cylinder has a piston therein one side of which is loaded by a spring and the other side of which is subjected to a pressure medium introduced into the cylinder. The cylinder is provided with an auxiliary release device comprising a screw coupling having a first coupling member which is rotatable but not axially displaceable and a second coupling member threadedly engaged with the first coupling member and acting upon the brake cylinder through an abutment coupling against the force of the load spring. The first coupling member is provided with a reversible thread and a second coupling means is provided to retain the second coupling member against rotation when the pressure acting upon the cylinder falls below a predetermined level.

摘要： A rail-brake magnet is suspended from structure on a railway vehicle at a predetermined distance above a rail when in its non-operating state by a spring. Abutment means are provided to limit the movement of the spring in the direction of raising the rail-brake magnet so that the spring is subjected to an initial stress when the rail-brake magnet is raised to its non-operating position. This initial stress on the spring may be adjusted.

摘要： The pressure in an air line in an air braking system for a railway vehicle is controlled by an operator's brake valve which is also constructed to maintain the pressure therein. A pressure monitor is responsive to the pressure drop across a restrictor in the air line or in a supply line leading from a source of compressed air. A control line is connected to an energy source through a shut-off device operable by the pressure monitor and through a two-position switch to be connected to a monitor device for brake release operation or to a second monitor device for the flow of air in the air line caused by defects or application of the emergency brake. The shut-off switch will move to the energy passing position only when a certain pressure difference in the restrictor is excceded. The two-position switch is actuated by the operator's brake valve and connects the brake release monitor device to the control line only when the operator's brake valve is in its brake release position. Otherwise, the two-position switch connects the control line to the monitor device for defect-originated air flow.

摘要： An air brake system for a railway vehicle has a brake control valve connected to a main air line which is maintained at a certain pressure when the brakes are released. Connected to the brake control valve is an air reservoir and a brake cylinder which is connected through suitable linkage to operate a friction brake. A valve device is provided which is actuated in response to the operating state of the friction brake and pressure in the main air line and includes a venting valve connected to the main air line so that the venting valve is opened during a simultaneous occurrence of the brake being in the braking state and the regular pressure level is maintained in the air line. Under other conditions the venting valve is closed.

摘要： A switching member positioned approximately in the plane of the brake disk has an actuating element therein which is displaceable radially with respect to the brake disk. The element is resiliently held in a rest position and is engageable by adjustable screws mounted on the ends of arms extending from the brake shoe suspension hangers pivotally mounted on each side of the brake disk. The extending arms are spaced with respect to each other in the peripheral direction of the brake disk. The switching member is connected to a fluid pressure source so that when a push button valve in the fluid pressure line is opened, the fluid pressure will be connected through the switching member to the atmosphere when the wear of the brake lining reaches a predetermined low level. The communication to the atmosphere is achieved by displacing the actuating member a sufficient distance so that a radial bore therein provides communication within the switching element between the source of fluid pressure and the atmosphere.

摘要： A brake cylinder has a reciprocating piston therein from which extends a non-rotatable sleeve surrounding a coaxial nonrotatable axially displaceable threaded shaft upon which is threaded a coupling nut. A pair of rotary couplings are provided on opposed sides of the coupling nut with the sleeve and the rotary couplings are actuable by axial displacement of the coupling nut. An axially displaceable control sleeve is resiliently urged in the braking direction against the coupling nut and is capable of limited axial displacement. The spring acting against the control sleeve has one end upon a fixed stop and a second stop is provided on the coupling nut which is spaced rearwardly of the first stop when the brake resetting device is in the inoperative position.

摘要： A balancing valve comprises a housing in which is mounted a pressure regulator valve for establishing a control pressure proportional to the load of the vehicle. A spring plate is supported on its edge within the housing and is subjected to a proportion of the vehicle load on an intermediate annular portion thereof. A flexible diaphragm is responsive to the force of the control pressure and acts against the central portion of the spring plate in opposition to the vehicle load. The spring plate is provided with a central opening having a plurality of slots radiating therefrom to reduce the spring rigidity of the plate. As a modification, the spring plate may be provided with a reduced thickness portion defining an annular area concentric to the center of the plate. A thrust element is supported in the center of the spring plate to be acted upon by the diaphragm.
