A water release system includes a compact aftercooler connected to receive hot, moisture laden compressed air from a compressor having a load cycle under control of a governor. A water release valve is connected between a header of the aftercooler and an unloader pressure line connected to the governor. The valve ordinarily remains open until it receives a certain, pressure value signal from the unloader line which is effective to close the valve. A switch is located in pressure sensing relationship with the aftercooler, and a solenoid valve is electrically connected to the pressure sensitive switch and pneumatically connected between the water release valve and the governor. When the pressure sensed by the switch is somewhat above that at which the water release value ordinarily closes, the pressure sensitive switch closes to energize the solenoid valve and thereby open the same, after which the water release valve operates automatically to open and close in response to pressure and lack thereof in the unloader line.

Water release valve for a compressed air system. It has a service connection for attachment to a low point of the compressed air system. The valve has a body which has an internal space, part of which is a cylindrical bore. It also has a pilot connection for attachment of a pilot pressure obtained from the compressed air system, and the valve has an exhaust port for releasing air and water from the system. It has one or more pistons placed in the cylindrical bore. At least one of the pistons has a position determined by the pilot pressure. The piston closest to the service end may be placed in two different positions. In one of the positions, it closes the flowpath from the service connection to the exhaust. In the second position, it opens the flowpath.

A tamper-resistant independent brake valve device for use in a brake equipment on railway locomotives including a main body casing carrying a movable handle, a rotatable cam, a pivotal cam dog and an exhaust and supply valve assembly, a spring housing attached to the main body casing by a plurality of one-way screws, a break-away adjusting screw for setting the maximum brake cylinder pressure on the railway locomotive, the pivotal cam dog including an enlarged head portion to preclude the insertion of a prying tool, and the pivotal cam dog having cam engaging roller which is rotated on a round head roller pin.

An air supply system having a multi-cylinder, two-stage air compressor including a pair of low pressure cylinders and a high pressure cylinder. A first intercooler interconnected between the outlet of one of the pair of low pressure cylinders and the inlet of the high pressure cylinder and a second intercooler interconnected between the outlet of the other of the pair of low pressure cylinders. An aftercooler connected to the outlet of the high pressure cylinder for effectively reducing the temperature of the compressed air supplied to a storage reservoir to near or at ambient temperature. A protective housing including a frontal screened opening for permitting a rotary fan to draw cooling air into the housing and including an internal shroud for directing the cooling air over the intercoolers and aftercooler.
