Abstract: The invention provides a brake release device for a braking arrangement. The braking arrangement includes friction pads, a friction surface and a first fluid path to convey fluid for controlling the application of the friction pads against the friction surface. The brake release device comprises a second fluid path to convey fluid for releasing the friction pads from the friction surface. The brake release device also comprises a selector valve coupled with the first and second fluid paths. The selector valve is capable to selectively acquire a first mode, a second mode and an intermediate mode. The first mode establishes fluid communication between the first fluid path and the braking arrangement. The second mode establishes fluid communication between the second fluid path and the braking arrangement. The selector valve is movable from the first mode to the second mode via the intermediate mode in which pressurized fluid in the first fluid path is relieved before entering the second mode. The brake release device may also comprise a pressure responsive interlock which controls switching between the first mode and the second mode when pressure in the second fluid path is above a threshold.

Abstract: A release graduating valve for freight brake control is provided for a railcar having a pneumatic control valve, emergency and auxiliary reservoirs each normally charged with pressurized fluid from a brake pipe and a fluid pressure activated brake cylinder device for applying the brakes on the railcar. A selectively operable release graduating valve can include a graduated release valve and a changeover valve which selectively interposes the graduated release valve to exhaust brake cylinder pressure in a graduated manner responsive to brake pipe pressure. Alternatively, the changeover valve can isolate the graduated release valve and direct the pneumatic control valve to exhaust brake cylinder pressure in a conventional manner. The changeover valve can be operated responsive to the pressure in an air pipe supplied with pressurized fluid from a remote source. A permanent release graduating valve can be provided wherein the changeover valve is omitted, in which case the brake cylinder exhaust is always controlled by the graduated release valve. Either configuration of the release graduating valve could be also be utilized in an ECP freight brake control system.

Abstract: A caliper brake device includes a brake shoe for exerting a friction force by sliding in contact with a disk, a caliper main body fixed to a vehicle and an actuator for pressing the brake shoe against the disk. The actuator includes an elastic film that is fixed to the caliper main body, a drive pressure chamber that is defined by the elastic film and to which a fluid is supplied, a valve that introduces the fluid to the drive pressure chamber, and a piston that is interposed between the elastic film and the brake shoe. The fluid is supplied to the drive pressure chamber and the elastic film swells toward the brake shoe, whereby the piston brings the brake shoe into sliding contact with the disk. The valve introduces the fluid to the drive pressure chamber when the brake is applied while limiting the discharge of the fluid from the drive pressure chamber when the brake is released.

Abstract: An apparatus incrementally reduces pressure in a first volume in response to an increase in pressure in a second volume. A valve body (110) defines a bore (111) that houses a piston (112) and supply and return passages (104,106) that communicate with first and second ends of the bore, respectively. The valve body also defines a release passage (170) that connects the bore with the first volume and an exhaust passage (180) that connects the bore with atmosphere. An inlet valve (140) opens when pressure in the second volume increases relative to pressure in the supply passage. An outlet valve (160) opens when pressure in the second volume decreases relative to pressure in the return passage. The piston is biased in a closed position against the first end and defines a passageway (120) through which the first and the second ends communicate. When pressure increases in the second volume, the inlet valve opens causing the first end (114) to pressurize and move the piston to an open position in which the release and exhaust passages communicate. This allows the first volume to vent gradually to atmosphere. As the pressure gradually equalizes between the first (114) and second (116) ends via the passageway, the piston returns to its closed position thereby discontinuing communication between the release and exhaust passages so that the first volume is cut off from atmosphere. When pressure decreases in the second volume, the outlet valve opens causing pressure to equalize between the supply and return passages via the passageway and to approximate the pressure in the second volume.
