摘要:
A light source for testing sites using a fluorescent dye is described. The light source can include a low voltage lamp or a low heat generating lamp. An emission from the fluorescent dye can be detected through a filter lens, which can include a primary filter and a trim filter. The filter lens can transmit the emission from the fluorescent dye and substantially block an excitation wavelength. The emission from the fluorescence dye is detected through a filter lens including a primary filter and a trim filter, through which the emission wavelength is transmitted, but the excitation wavelength is substantially blocked.

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.

A safety wire plier includes a pair of plier arms with each of the arms including a jaw end and a handle. The plier arms of the safety wire plier are pivotally connected to each other for movement in either an open or closed position. The safety wire plier also includes a sealed lock for releasably locking the safety wire plier in the closed position.

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. The coupling member can include a self-sealing valve assembly that prevents opening the coupling member until a proper coupling interconnection with a system to be serviced has taken place. The purge fitting can be incorporated in the coupling member or other service device.
