Abstract
A portable, hand held device for testing the air brakes of a tractor trailer type truck. The device is generally comprised of an elongated body having a cavity bored therein which extends perpendicularly to the longitudinal axis of the body, and an inlet and outlet attached to opposite ends thereof. A valve assembly consisting of a series of co-linearly mounted, axially displacable springs and plungers are operatively positioned within the bore, and effectively open or close the fluid communication between the inlet and outlet. A first hose extends between a compressed air tank and the inlet, and a second hose extends between the outlet and the glad hand of the truck. A lever is pivotally attached to the body for effecting operation of the valve assembly, and thus may be selectively moved to effect the flow of compressed air from the compressed air tank to the glad hand. A pressure regulator and gauge are also incorporated into the device for permitting accurate pressure tests to be conducted on the air brakes.
