Filed:

May 1, 2007

Appl. No.:

11/797165

Inventors:

Jeffrey B. Murphy - Millersville PA, US
Eric I. Shultz - Mount Joy PA, US
Thomas L. Crandall - York PA, US

Assignee:

RTI Technologies, Inc. - York PA

International Classification:

G01M 17/00

US Classification:

701 33, 701 29, 701 36, 340438, 340439, 34042616

Abstract:

Automotive service equipment and method of servicing an automotive vehicle use an automotive service machine having at least one automatic mode of operation during which an operator is not required to be present. A first, stationary communication module connected to the service machine receives first signals from the machine indicating the status of an automatic mode of operation of the machine and wirelessly transmits second signals communicating when an operator's attention to the machine is required. A second, portable communication module remotely receives the second signals and in response activates a signaling device in the second module for signaling an operator that attention to the machine is required. Thereby, during vehicle servicing the operator can perform other tasks within the workshop, thus being more productive and efficient.

Abstract:

A method and an apparatus for filling tires with high purity nitrogen involves evacuating and then filling tires with nitrogen. An automated apparatus has a mode of operation which can be selected from among a four tire service, a spare tire service and a top off service, with or without vacuuming during evacuation. With the four tire service, four tires connected to the apparatus are evacuated and then filled to set front and rear tire pressures. With the spare tire service a single tire connected to the apparatus is evacuated then nitrogen filled to a set tire pressure. A five tire service for evacuating and filling two front and two rear tires and a spare tire is also disclosed. The top off service of a tire connected to the apparatus involves sensing the tire pressure and then evacuating or nitrogen filling to obtain a set tire pressure. Evacuation of a tire is automatically stopped when a set minimum pressure level or a set maximum time limit for evacuation is reached. The apparatus permits accurate filling of tires with high purity nitrogen in an efficient manner without requiring the operator to attend the apparatus during the process after initial setup.

International Classification:

US Classification:

141 98, 141 99, 141192, 141302, 188352

Abstract:

Automotive service equipment for brake fluid exchange includes a central unit having a controller for operating the equipment and a communication module for wirelessly communicating with each of a plurality of remote bleed modules to control bleeding brake fluid from respective brake bleeders of a vehicle connected to the modules. The brake fluid from the brake bleeders is stored in containers in the modules for later removal. When disconnected from the brake bleeders, the modules are moved to docking stations on the central unit for emptying brake fluid from the module containers and vacuum charging the containers for brake bleeding. The automotive service equipment and related method of performing brake fluid exchange in an automotive vehicle avoid the use of hoses for returning the waste fluid to the central unit thus reducing the problem of storage and handling of such hoses and spillage of residual fluid left in the hoses.

B23P 11/00

US Classification:

137861, 29428

Abstract:

A multi-block manifold facilitates assembly of the manifold in a fluid handling apparatus during manufacture and disassembly and removal of a secondary manifold block of the manifold during service without disconnecting external tubes and flow control devices from the manifold. The external tubes are isolated and integral to a primary manifold block of the manifold which is permanently mounted in the apparatus and the flow control devices are integral to the secondary manifold block which is quickly, releasably secured to the primary manifold block in the apparatus.

Abstract:

A method is provided for operating a refrigerant recovery, recycling and recharging system having a compressor to recover, recycle, and/or recharge the refrigerant in a closed refrigeration circuit coupled to the system. The method includes compressing refrigerant with the compressor, stopping the compressor, re-starting the compressor, and relieving a pressure differential across the compressor at the time of re-starting the compressor.
