Application June 2, 1948, Serial No. 30,532
1 Claim. 1
This invention relates to a testing device for fuel pumps.
It is an object of the present invention to provide a testing device which can be disposed in the fuel supply system and used while the engine is running to check the pressure of the fuel delivered by the pump and the amount over a given period of time and whereby the observation can be made by reference to indications on a metering glass.
Other objects of the present invention are to provide a fuel pump testing device which is of simple construction, inexpensive to manufacture, easy to operate and efficient in operation.
For other objects and for a better understand ing of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. l is an elevational view of the testing device connected to a pump and to a carburetor and to a fuel tank from which the fuel is taken and returned.
Fig. 2 is a top plan view looking upon the top of the metering tank and on the gauge.
Fig. 3 is a sectional view, in elevation, taken on line 3-3 of Fig. 1.
Fig. 4 is a fragmentary sectional view taken on line 4-4 of Fig. 1.
Referring now to the figures, l represents a fuel supply tank from which gasoline is pumped toward a carburetor II by a fuel pump l2 to be tested. Into the tank i0 there is extended a sump l3 from which a tube l4 extends to the fuel pump l2 adapted to be driven by a movable part of the engine. In a pipe line i5 extending to the carburetor l I there is interposed a fitting I! having a regulating valve i8 and a pressure gauge 19. This fitting is mounted upon the top of the metering glass or transparent cylinder 2i having a central pipe 22 which is connected to a fitting 23 with a pet cock 24 therein for the purpose of draining off the flow of fuel connected in the glass tank 2 i. The fitting 23 extends to the tank Ii. A filler pipe 26 is provided on the tank ill through which fuel is extended when filling the tank [0.
The pipe 22 is perforated throughout its height as indicated at 27 and has a closure plug 28.
The tank 2| is formed of a transparent wall 30 having indications thereon which will indicate the results of the test.
In the fitting I1 is a pressure regulating valve 29, Fig. 4, which is held by a spring 3! on a valve seat 32. The spring 3| can be adjusted by turning a regulating screw 33 having a knurled handle 34 thereon. When the proper setting is made and a pressure reading is taken, the fuel will be forced to the carburetor. The valve 29 will have remained closed and the setting will be such that the carburetor will be constantly supplied to maintain the engine in operation. When the required pressure has been established to open the valve 29, the excess fuel will pass to the glass tank 2. If a small amount of excess fuel is extended to the tank 2!, the fuel pump is not operating properly. The fuel pump will then need repair to establish the pressure requirements. If a large amount of fuel is supplied for a given setting of the valve 29, the pump is in a good condition and would not need repair. A tube 36 is connected with the fitting II to a nipple 31 so as to extend downwardly into the glass tank 2!. The fuel leaving the fitting and entering the glass tank 2|, will enter at the bottom so that the glass will not be splashed.
The metering tube 22 has holes 27 which when pet cock 24 is open allows the gasoline to be bypassed to the tank i0 so that the level of the gasoline in the glass 2| would be raised to the mark good. If the good level is not reached, then the pump being tested is in either a fair or bad condition. The gasoline will pass out of the glass tank 2! through the metering holes 21. The higher the gasoline in the glass tank 2 i, the greater the number of holes through which the gasoline will lead.
The glass tank 2| may also be used independently for testing for air in fuel lines as by connecting the upper end of the tube 36 in the fuel line and returning the fuel back to the line through the fitting 23 or pet cook 24 the fuel passing through the tank will circulate therethrough continuously and when air develops in the line bubbles will show in the tank.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.
I claim:
In a pump-testing apparatus, a fitting, a transparent cylinder arranged adjacent said fitting and having markings on its outer surface, a tube having its upper end connected to said fitting and its lower end terminating within said cylinder adjacent the lower end thereof, valve means connected to said fitting for regulating the flow of fuel in said tube, a vertically disposed pipe extending longitudinally through said cylinder, there being a plurality of spaced perforations in said pipe for the egress therethrough of fluid, and a manually operable valve arranged on said tube for controlling the flow of fluid from said tube.
