Abstract: A two solenoid pressure modulated ABS relay valve incorporates a quick release valve in the control air circuit to allow a majority of the air in the control cavity to escape directly to ambient. The orifice through the exhaust solenoid need only handle a relatively small volume of air upstream of the quick release valve, i.e., between the quick release diaphragm and the inlet solenoid seat.

Abstract: A trailer air dryer is provided to minimize contamination, leakage or freeze-up of the valves used in a pneumatic braking and suspension system caused by moisture or foreign particles in the system. A bypass assembly is provided to ensure normal brake operation should the filters or drying material/desiccant become plugged. In one embodiment, an audible signal or warning is provided to the operator indicating need for servicing the trailer air dryer.

Abstract: The support includes a tubular casing (1), whereby the remaining components of the support are accommodated in the interior of this casing. A stop (15,16) exists at the respective end of the casing. An end piece (12,13) is accommodated in the respective end portion of the casing (1) whereby the outer front surface (22,34) of the respective end piece rests on the assigned stop (15,16). A terminating or closing device (25,26) is assigned to that one side of the respective end piece, which faces the interior of the support, whereby a tubular interior part (10) extends between said terminating devices. A sealing ring (35) is arranged between the front surface (22,34) of the respective end piece (12,13) and the assigned stop (15,16). The outer diameter of this sealing ring (35) before the assemblage of the support is equal to the outer diameter of the remaining components lying in the interior of the support or it is smaller than the diameter of the remaining interior parts.

Abstract: A multi-way pressure control valve for an electromagnetically actuatable multi-way control valve for slip-controlled hydraulic automotive vehicle brake systems, for providing a flow connection between at least one wheel brake and a high-pressure source or a low-pressure accumulator.

Abstract: A scooter rear wheel brake comprises a rear wheel cover which is mounted on the scooter footboard such that the rear wheel cover is located over the rear wheel of the scooter. The rear wheel cover is provided with a brake applying block and a brake shoe mount corresponding in location to the brake applying block. The brake shoe is linked with the brake applying block by which the brake shoe is actuated to act on the rear wheel in motion.
