Abstract: A system for servicing a fluid system can employ a pressure-reducing source to perform the desired service. The fluid system can be an engine cooling system or other fluid system.

Abstract: An accessory attachment winding device with rolling and positioning capabilities for installing, removing and storing a tonneau cover or other vehicle covering is disclosed. The accessory system is provided with preferred features of integral-unitary construction or multiple base member construction with extending inter-fitting and sliding parts, so that the device can be adjusted in terms of position and dimension to connect and attach to complimentary coupling or connection portions of a tonneau, vehicle or other covering. In its method and function of operation the device houses and presents complimenting coupling members which can be adjusted in terms of their positional relationship as housed in a respective base member, or in terms of the extensible, sliding and positional features of the cooperating base members utilized in the method and device of the present invention.

Abstract: A method and apparatus for removing fluid from a fluid system. The method or apparatus can include a pressure-reducing source to facilitate fluid removal. The system can be an engine cooling system or other fluid system.

Abstract: A flexible joint assembly includes a joint assembly inlet, a joint assembly outlet, and a fluid flow path between the inlet and the outlet. The fluid flow path includes a first pivot joint, a second pivot joint, and a central fluid conductor fluidly coupling the pivot joints. A method of servicing a fluid system includes transporting a fluid through a service device including the flexible joint assembly.

Abstract: A method and apparatus for servicing a pressurized system is described. A purge fitting can be used to vent the pressurized system. Venting can release a gas, such as air, from the system. The pressurized system can be a climate control system (e.g., an air conditioning or refrigeration system), a brake system, a hydraulic system, or a service device for servicing a climate control system. The purge fitting allows air that may be trapped in the pressurized system to be vented by depressing a purge actuator, such as a purge button attached to the fitting. The air can be vented from an opening adjacent to the actuator or other orifice. By purging air directly from the system, the amount of air introduced into the system during servicing can be minimized. The invention also features a coupling member that can be compact in size.

Abstract: A fluid delivery apparatus provides for controlled delivery of fluids into a fluid system. The fluid delivery apparatus can allow a defined volume of fluid to be delivered to the fluid system cleanly, minimizing fluid waste and spillage. The fluid delivery apparatus can provide a mechanical advantage allowing the fluid to be delivered easily and efficiently to a pressurized fluid system. The apparatus can have a piston and handle arrangement that can reduce wear of the apparatus.

Abstract: A service device connects to a service port of a pressurized system. The device includes a valve opening member for opening a valve within the port. The position of the valve opening member within the connector is adjustable or self-adjusting. The adjustable valve opening member allows the valve in the service port to be opened fully by the connector over a range of valve positions within the port. The device can attach to a service unit for servicing the pressurized system. The system can be an air conditioning or refrigeration system.
