    摘要： In a distributed power railroad train, an apparatus for equalizing the equalizing reservoir pressure in the remote power unit and the brake pipe pressure. With these pressures equal, the remote unit cannot charge the brake pipe while the lead unit attempts to vent the brake pipe to command a brake application at the railcars of the train.

    摘要： A valve having two pistons slidable in a through bore and spring loaded apart from each other against stops, an inlet port communicating with the space between the two pistons and passages through the two pistons controlled by nonreturn valves which prevent back flow to the space between the two pistons. A plunger is slidable in a cylinder which is in communication with the space between the two pistons, the plunger carrying the movable contact of an electric switch which operates an alarm device. The arrangement is such that acceptable variations in the pressure of fluid fed to the space between the pistons through the inlet port is compensated for automatically by movement of the pistons to alter the volume of the space and thus maintain the pressure of fluid therein substantially constant, whereas the plunger, which is normally supported by the pressure of fluid within the space between the pistons so as to hold the electric switch open, moves with an unacceptable loss of pressure within the space between the pistons to close the electric switch and operate the alarm device.
