Publication number: 20240060486Abstract: An air treatment system includes an electric compressor for compressing air, an air flow valve positioned in a delivery line downstream of the electric compressor, and an electropneumatic valve connected to the air flow valve. A controller having control logic receives a system pressure and activates the electropneumatic valve. The control logic activates the electropneumatic valve to provide a pneumatic control signal to the air flow valve to partially close the delivery line in response to the system pressure being greater than a first predetermined pressure.Type: ApplicationFiled: August 22, 2022Publication date: February 22, 2024Inventor: Richard J. Conklin

Patent number: 9802593Abstract: 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.Type: GrantFiled: June 7, 2011Date of Patent: October 31, 2017Assignee: Bendix Commercial Vehicle Systems LLCInventors: Timothy J.

Patent number: 8731795Abstract: 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.Type: GrantFiled: October 12, 2010Date of Patent: May 20, 2014Assignee: Bendix Commercial Vehicle Systems LLCInventors: Timothy J. Frashure, Richard J. Conklin

Patent number: 8521389Abstract: 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.Type: GrantFiled: July 30, 2012Date of Patent: August 27, 2013Assignee: Bendix Commercial Vehicle Systems LLCInventors: Travis G Ramler, Richard J.

Publication number: 20120296543Abstract: 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.Type: ApplicationFiled: August 6, 2012Publication date: November 22, 2012Applicant: BENDIX COMMERCIAL VEHICLE SYSTEMS LLCInventors: Matthew E. Rogers, Mark A. Bennett, Ron R. Stahl, Michael D. Tober, Kenneth A. Grolle, Richard J. Conklin, Timothy J. Frashure, David W. Howell

Patent number: 6358300Abstract: 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.Type: GrantFiled: March 28, 2000Date of Patent: March 19, 2002Assignee: Honeywell Commercial Vehicle Systems Co.Inventors: William P.

Patent number: 6358291Abstract: 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.Type: GrantFiled: September 17, 1999Date of Patent: March 19, 2002Inventors: James P. Koenig, Leonard Quinn, Richard J. Conklin, Fred Hoffman

Patent number: 6125553Abstract: A control module for a twin air dryer system monitors which dryer was used for drying in the previous cycle. The most recently used dryer is then the first to be regenerated. This ensures that the most recently regenerated dryer is used to dry incoming air. This occurs regardless of the drying mode, i.e., whether it is high air use or normal brake system use. The system minimizes the risk of dryer saturation and loss of function. Moreover, maintenance requirements are simplified, since the air dryer cartridges are more evenly used.Type: GrantFiled: May 13, 1999Date of Patent: October 3, 2000Assignee: AlliedSignal Truth Brake Systems CompanyInventors: Leonard Quinn, Richard J. Conklin, III

Patent number: 6076272Abstract: A compressed air dryer assembly for an air braking system provides for uniform compression of a desiccant bed. Guidance of a housing urged into a dryer shell by a spring force is provided at radially inner and outer regions. This guidance allows for a wide range of movement so that the desiccant bed is maintained under uniform compression. In addition, a sliding seal effectively provides a wide range of movement and yet limits communication between the inlet and outlet openings.Type: GrantFiled: October 29, 1998Date of Patent: June 20, 2000Inventors: Richard J. Conklin, III, Scott McGill Alexander
