Cleaning facility for tubing systems of vehicles

#1. Field of the Invention

#The present invention relates to a cleaning facility, and more particularly to a cleaning facility for cleaning tubings of vehicles.

#2. Description of the Prior Art

#FIG. 1 is a front perspective view of a housing of a cleaning facility for cleaning tubings of vehicles in accordance with the present invention;

#FIG. 2 is a rear perspective view of the housing;

#FIG. 3 is a diagram illustrating the complete tubing systems of the cleaning facility;

#Referring to the drawings, and initially to FIGS. 1-3, a cleaning facility in accordance with the present invention is provided for cleaning various tubings of the vehicles, such as the lubrication tubings, the air conditioning tubings, the fuel supplying tubings, etc., and comprises a housing 10 having a control panel 11 provided on top thereof. FIG. 3 illustrates the complicated and complete tubing systems of the cleaning facility including both the air and the fluid flowing systems for flushing and recycling and purging purposes etc.

#Referring next to FIGS. 4-6, and initially to FIG. 4, illustrated is the air and the fluid flowing systems for the flush and recycle operations of the cleaning facility. An air regulator or lubricator or filter 20 and an oiler 21 are provided and may be attached onto or into the housing 10 and coupled to an air tubing system 19. A shop air source or a pressurized air source 22 may be provided and coupled to the air filter 20 and the oiler 21 for allowing the pressurized air to flow into the air tubing system 19 after the pressurized air has been flown through the air filter 20 and the oiler 21 and has been filtered by the air filter 20. An air pressure gauge 23 is coupled to the air tubing system 19 for detecting and indicating the air pressure within the air tubing system 19.

#The air tubing system 19 is then coupled to a switch valve, such as a 2-way, 3-way, or 4-way and two position manual and mechanical switch valve 24 which may be actuated or operated by a switch knob 241 (FIG. 1) and which may be used for controlling or switching the fluid flowing system on (25) and off (26); i.e., for switching on (25) or cutting off (26) the fluid flowing system. An air switch valve 27, such as a 4-way and two position manual and mechanical switch valve 27 which may be actuated or operated by a switch knob 271 (FIG. 1) and which may be used for controlling or switching the air flowing system on (28) and off (29); i.e., for switching on (28) or cutting off (29) the air flowing system. The operations of the air and fluid flowing systems will be described in further details hereinafter.
