  • Patent number: 9180854
    Abstract: A system and method of controlling an air dryer system having first and second air dryers configured to receive compressed air from a compressor, such as a compressor of a vehicle, including operating the first and second air dryers in a first mode corresponding to a high flow mode wherein the first and second air dryers are connected in parallel with the air compressor, monitoring a condition related to a low compressor output state, and operating the first and second air dryers in a second mode corresponding to a continuous flow mode when the low compressor output state is detected.
    Type: Grant

  • Patent number: 7175006
    Abstract: For an air-operated disc brake there is provided an internal brake actuator stroke indicator which provides an indication, readily ascertained from outside the brake caliper, of the amount of actuator stroke remaining in a disc brake apparatus before a remaining available actuator stroke limit is reached. In one embodiment, the stroke indicator is a mechanical device, readable through a sight glass in a caliper port, coupled to the brake actuator in a manner which results in rotary motion of the indicator when the brake actuator is displaced through its stroke. Alternatively, the indicator may be a rotary sensor such as an electrical potentiometer coupled to the actuator, where the potentiometer sends an electrical signal indicative of the actuator stroke to an external display, such as a remote actuator stroke display at a vehicle operator's position.
