摘要： A brake system wherein the single actuator is freely mounted to a first brake beam so as to align its force application axis with the axis of a first force transmitting rod connected at its other end to a transfer lever on a second brake beam. A second force transmitting rod connects the transfer lever back to the first brake beam. The mounts for the actuator and the transfer lever are designed for use with brake beams of dual actuator brake systems.

摘要： A railway car control valve comprises a brake pipe port, an auxiliary reservoir port, a main piston configured to compare air pressures at the brake pipe port and the auxiliary reservoir port, and a one-way check valve positioned intermediate the brake pipe port and the auxiliary reservoir port. The one way check valve comprises a body having a bore extending from its first end to its second end, an elongated insert configured to reduce the rate of air flow through the body, and a sleeve received on the insert's outer surface. The insert is received in the body bore. One of the insert and the sleeve is configured to move between a first position and a second position that either allows air to flow or prevents air from flowing, respectively.

摘要： A control valve having, in a series with a first inlet valve of a quick brake volume, two different rates of flow restrictions operable as a function of the position of the piston. The first flow rate of one first restriction is insufficient to cause the piston to a braking position for applying a minimum service application for first range of piston positions which would generally be produced by the mechanical vibration. The second restriction has a greater flow and will accelerate the piston to a braking position for a second range of piston positions which will be produced by the reduction of the brake pipe pressure on one face of the piston. By providing two flow rates, the valve becomes insensitive to mechanically produced forces while maintaining the reaction time of the valve to fluidically produced reduction of brake pipe pressure.
摘要翻译：具有与快速制动容积的第一入口阀串联的控制阀具有两个不同的流动限制速率，可根据活塞的位置进行操作。一个第一限制的第一流量不足以使活塞进入制动位置，以对通常由机械振动产生的第一活塞位置范围施加最小的服务。第二限制具有更大的流量，并且将通过在活塞的一个表面上减小制动管压力而产生的第二活塞位置范围将活塞加速到制动位置。通过提供两个流量，阀对机械产生的力不敏感，同时保持阀的反应时间流体地产生制动管压力的降低。

摘要： A railway car control valve comprises a brake pipe port, an auxiliary reservoir port, a main piston, intermediate the brake pipe port and the auxiliary reservoir port, configured to compare an air pressure supplied at the brake pipe port with an air pressure supplied at the auxiliary reservoir port and a one-way check valve positioned intermediate the brake pipe port and the auxiliary reservoir port. The one way check valve comprises a body having a first end, a second end, and a bore extending from the first end to the second end, an elongated insert defining an outer surface, the insert configured to reduce the rate of air flow through the body, and sleeve received on the insert outer surface. The insert is received in the body bore. One of the insert and the sleeve is configured to move between a first position that allows air to flow in a first direction from the brake pipe port to the auxiliary reservoir, and a second position that prevents air from flowing in a second direction from the auxiliary reservoir port to the brake pipe port.
