摘要： An empty/load changeover valve device for a railway car having a proportioning valve via which the car control valve supplies brake cylinder pressure. The proportioning valve comprises a balance piston having equal opposing pressure areas and a combined supply and release check valve, one pressure area of the balance piston being subject to air pressure supplied to the brake cylinder under all conditions of loading. The opposing pressure area of the balance piston is either pressurized or depressurized depending upon the car being in an "empty" or "load" condition, thereby establishing either a nonproportioning or a proportioning mode of brake control. Integrating the release check valve with the supply valve so as to have a smaller effective pressure area, the release check valve can be opened with low force to exhaust brake cylinder pressure during brake release, thereby making possible a reduced size empty/load changeover valve device.

摘要： This invention relates to a railway vehicle brake apparatus wherein an air operated load compensating relay valve device is disposed between and rigidly secured to both a brake control valve of the graduated release type and the control reservoir for this brake control valve. A plurality of passageways extend through the load compensating relay valve device to provide communications through which fluid under pressure is supplied from the control reservoir and also an auxiliary reservoir to the brake control valve that has a supply and release valve mechanism which is operable in response to variations of pressure in a train brake pipe relative to a constant pressure maintained in the control reservoir to effect the supply of fluid under pressure from the auxiliary reservoir to the load compensating relay valve device to cause a brake application or to release fluid under pressure from this relay valve device to atmosphere to cause a release of a brake application.

摘要： A water ride including vehicles that ride on a track and using water for braking. A run-out section of the track is provided after a drop or down chute section, and the track in the run-out section runs through a pool of water at a depth causing at least a portion of a vehicle riding on the rails to contact a depth of the water to achieve vehicle braking. Significantly, the new water ride is adapted to adjust or set a variable height of the rails in the run-out chute or pool to adjust the depth of water providing water drag on a vehicle traveling through the run-out section based on the vehicle weight. A braking force is applied by the water that is proportional to vehicle weight, and the water ride may be thought of as slowing vehicles with a range of weights at about the same deceleration rate.

摘要： An electronic load weigh device is used with a railcar truck control unit. A relay valve provides to a brake cylinder a pressure proportional to the pressure impinging upon its control port. A first feedback signal is indicative of the pressure at the control port. A second feedback signal is indicative of the load borne by the truck. A pressure switch opens when pressure within a trainline changes to a level indicative of an emergency. By controlling the opening and closing of application and release magnet valves, a controller controls the pressure impinging on the control port and thereby service braking of the wheels of the truck. The load weigh device includes (i) circuitry for electronically compensating for the load during braking and (ii) a mechanism for granting the circuitry exclusive control over the magnet valves. Should such emergency occur, the mechanism responds to such emergency by disconnecting the controller from the magnet valves. This gives the circuitry exclusive control over the magnet valves. The circuitry compensates for the load borne by the truck during emergency braking by selectively opening and closing the magnet valves, according to predetermined criteria using the feedback signals, thereby controlling the magnitude of the pressure impinging upon the control port. Absent such emergency, the mechanism responds to such absence by connecting the controller to the magnet valves whereby such service braking on the truck is normally controlled, yet the circuitry is still enabled to compensate for the load during such service braking.
摘要翻译：电子负载称重装置与轨道车辆卡车控制单元一起使用。继动阀向制动缸提供与撞击其控制端口的压力成比例的压力。第一反馈信号指示控制端口处的压力。第二个反馈信号表示卡车承受的载荷。打开一个压力开关，当列车内的压力变为指示紧急情况的水平时。通过控制打开和关闭应用和释放电磁阀，控制器控制撞击控制端口的压力，从而维持卡车车轮的制动。负载称重装置包括（i）用于在制动期间电子补偿负载的电路，以及（ii）用于授予对电磁阀专用控制的电路的机构。如果发生这种紧急情况，则机构通过将控制器与电磁阀断开来应对这种紧急情况。这使得电路专用于磁阀。该电路通过使用反馈信号根据预定标准，通过选择性地打开和关闭磁阀来补偿卡车在紧急制动期间承载的负载，从而控制撞击控制端口的压力大小。没有这样的紧急情况，机构通过将控制器连接到电磁阀来应对这种缺失，由此在卡车上的这种工作制动被正常地控制，而电路仍然能够在这种制动期间补偿负载。
