International Classification:

B01D 5328

US Classification:

95 91, 95117, 95122, 96118, 96144, 96154

Abstract:

A drying material disposed in the passage of a compressed air system for removing moisture from air or gas includes a plurality of semi-rigid porous substrates impregnated with lithium chloride. The drying material is formed by preparing a saturated solution of lithium chloride and a nonflammable solvent. Porous substrata are contacted with the saturated solution to wet the substrata surface. The wet substrata are heated at a sufficient temperature for a sufficient duration to drive off excess liquid from the substrate. A desiccant comprising lithium chloride impregnated substrata is produced.

International Classification:

B60T 8/34

US Classification:

3031181, 303 56, 303 40

Abstract:

A locking control valve is provided. This control valve includes a valve body that further includes a first locking member, and a handle attached to the valve body. The handle is moveable between a first position and a second position for controlling the operation of the valve and further includes a second locking member. The first locking member and the second locking member cooperate with one another to retain the handle in the second position when so desired by the operator of the vehicle.

US Classification:

701 70, 701 76, 303 7, 303 64

Abstract:

Methods and valve arrangements for controlling the flow of pressurized air from a tractor to a trailer reservoir and to a trailer spring brake chamber. In one exemplary embodiment, pressurized air from a tractor is supplied from a tractor to the trailer reservoir and to the trailer spring brake in different filling modes based on a user input. In another exemplary embodiment, pressurized service air is used to charge or partially charge the trailer reservoir.

International Classification:

B60T 8/60
B60T 7/12
B60T 8/24

US Classification:

701 94

Abstract:

A vehicle braking control system includes a vehicle brake associated with a wheel on the vehicle. A pedal activated by an operator of the vehicle controls application of the brake. An electronic control unit determines a grade mode of the vehicle and controls application of the brake independent of the operator activating the pedal while in an automatic braking mode. The electronic control unit sends a control signal to apply the brake in a manner to reduce brake fade while controlling a speed of the vehicle when the electronic control unit is in the automatic braking mode and the vehicle is in a downhill grade mode.

International Classification:

B60T 7/12

US Classification:

701 70

Abstract:

A vehicle, air brake system is presented with an improved service work brake arrangement. The arrangement may provide a service work brake function or both a service work brake function and a parking brake function for the vehicle. The arrangement may provide an improved service work brake arrangement disposed within a housing for reducing the number of components and plumbing required to achieve this functionality versus prior known systems. The arrangement may utilizes a pneumatic latching valve to deliver pressurized air for applying a vehicle's service brakes. The pneumatic latching valve opens upon receiving a pneumatic control signal from an electronically controlled valve and closes upon receiving a pneumatic control signal from another source. In addition, a controller and control logic may be provided for controlling the arrangement.

US Classification:

188152, 701 70

Abstract:

A vehicle braking system includes a brake associated with a respective wheel of the vehicle, a multi-pressure valve associated with the brake, and a controller electrically communicating with the multi-pressure valve. The multi-pressure valve receives fluid at a first pressure at a supply port and is capable of delivering the fluid at a delivery port at a plurality of pressure profiles. A control signal is transmitted to the multi-pressure valve. The multi-pressure valve delivers the pressurized fluid to the brake, via the delivery port, at one of the plurality of delivery pressure profiles based on the control signal.
