Patented Mar. 31, 1953 s PATENT OFFICE FUEL PULSATION DAMPENER AND .PRESSURE REGULATOR Joseph T B. Witt, Fairfi'cld, .Application'Marchfl, 1947, Serial-No.736348 2 Claims.
. Y 1 This invention relates to improvements in automatic fuel pulsation dampener and pressure regulator, particularly adapted, though not necessarily limited in use with internal combustion engines, for controlling the fuel pressure at the carburetor, according to the pull which the motor .or engine is subjected to under various throttle openings of the carburetor, causing the pressure delivered against the inlet valve (needle valve) ,of the; carburetor to be at aminimum when the motor is idling or under a .light pull, and to automatically cause the pressure at that point to increase to the maximum as the motor is subjected." to a maximum pull, or throttle opening. Another object is to provide a device of this character, which. will eliminate the jiggling or hammering action of the needle valve against the needle valve seatand float lever in the carburetor, whichuis caused by the pulsating action of the fuel pumps, thereby reducing wear on. the carburetor, and giving more carburetor protection.
a. further object is to provide an improved automatic pressure regulator which is incorporated in a filter-damper, and which will result fuel economy and an elimination of flooding troubles, caused by high pressure at the carburetor, whether such flooding is caused from a high pressure fuel -pump, or due to other reasons, such-as expansion of fueliin the gas line, due to hea't,etc.
Asti-ll. further object is to provide an improved "de'vicejfoflgthis character, which is operated by the vacuum from the motor, a high vacuum. operating :to lower the pressure at the carburetor, thereby causing the fuel level in the carburetor to be lowered, 'thus causing a leaner: mixture whenzthe ishigh, or when-the motor is not-under a heavy load.
v To theattainment of these-ends, and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed, and shown in the accompanying drawing illustrating this invention, in which:
Fig. 1 is a side elevation of the chassis of a motor vehicle, showing this invention applied thereto.
Fig. 2 is an enlarged view, in elevation, of this Fig. 4 is a detail perspective view of the flexible diaphragm, and the valve operating ,linkor member attached thereto.
Referring more specifically to the drawing, the device consists essentially of a body portion l0, having an inlet opening I l, to which apipe I2 is connected, and an outlet 13, to which a pipe 1-4 is connected. A sediment bowl or chamber l5is secured to the body, preferably by means of a yoke or ball IB-pivoted to the body, as at H, and which passes under the bowl. A screw .l'la is carried by the yoke, and projects into a spacing cap 18, which engages the bottom of the bowl. Adjustably carried by the screw is a nut 0r collar [9, that is adapted to be moved into contact with the cap 18, whereby to secure the bowl [5 removably in position.
Arranged within the bowl to extend thereacross, is a steamer or filter screen 20, which is provided withan opening 21a, arranged to communicate with the inlet end 2| of the outlet pipe [4, so that the fuel, before entering the passage 13, must pass through the screen. The'filtering screen is also arranged in alinement with,- and extends across, the outlet end 22a of the inlet pipe l2, so that the fuel entering the pipe I2 will. flow through the screen into the bowl 1 5,
which latter constitutes a sediment chamber and reservoir. Fromthe chamber, the fuel, after being filtered, will flow through the screen and into the outlet pipe 14. The screen is heldin position in any suitable manner, preferably by .the periphery thereof beingclamped. or gripped between the edge or the bowl andsthe gasket or sealing ring t9.
A cap member 22- is secured. in position in any suitable mannensuch by means of screws or bolts 23, and. between the cap member 22- and the body portion I50, isdisposed a flexible diaphragm. that has secured to it on opposite sides thereof, protector plates 25. Secured to and depending from the diaphragm, is a valve operating link or member 26, which is provided with a laterally projecting arm or extension 21, having an opening 28 therein.
The member 26 is of a length to extend below the body portion l0, and a valve 29 having a projection 30, is' carried by said extension 21, the valve being held in position with respect thereto by the projection 30 being seated in the opening 28. This valve controls the outlet end of the passage II, by abutting the end thereof, which forms a seat for the valve. The rounding or circular shape of the projection 30 adapts the valve to rock with respect to its seat formed by 3 the edge of opening 28, so as to accurately abu the seat at the outlet end of the inlet passage I I.
An adjusting screw 3| is threaded into the cap member 22, and a coil spring 32 is seated in the cap member, with one end abutting the protector plate 25 on the diaphragm 24, and the other end engaging the adjusting screw 3|. The movement of the diaphragm is influenced by engine suction, and by adjustment of the screw 3 I. The degree of engine suction to actuate the diaphragm, and the extent of such actuation of the diaphragm, may be varied, as such adjustment will vary the stress of the spring 32 with respect to the diaphragm.
The space 33 above the diaphragm constitutes an air space, and a vent opening 34 is provided to balance the vacuum. The vent opening pref erably passes through the screw 3|, and communicates with said air space.
When the device is installed, the inlet pipe 12 is connected with a fuel pump 35, which receives its supply from a tank 36, through a pipe 37.
The outlet pipe [4 is connected to the carburetor 38. The chamber 33 on the upper side of the diaphragm 24, is connected by means of a pipe 39, to the engine intake manifold 40, so that suction in the engine will be manifested in the chamber 33, and upon the diaphragm 24, through the pipe 39, to actuate the diaphragm and thereby control the movement of the valve 21 with respect to its seat at the outlet end of the intake passage I l. Therefore, by varying the stress of the spring 32, by adjusting the screw 31, the amount of suction in the engine to actuate the diaphragm 24 and valve 21, may be varied.
By the installation of this invention in the fuel line between the pump 35 and the carburetor quired.
In operation, the spring pressure against the diaphragm is higher than the fuel pressure against the diaphragm. When a low vacuum is created, the spring 32 forces the diaphragm 24 away, permitting the valve 21 to open, which allows higher pressure to be transmitted to the carburetor. pulls the diaphragm against the spring 32, clos- When the vacuum is increased, it
ing the valve 21, and allowing less pressure to be transmitted to the carburetor.
Without the installation of this improved unit,
' the pressure remains at a maximum at all times. Furthermore, by providing low pressure at the carburetor when only low pressure is required,
means that at that time the fuel level in the carburetor will be lowered and a leaner mixture 4 will result, thus preventing waste of fuel, without damage to the engine.
While the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction, and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.
What is claimed as new is:
1. In a device of the character described, a chamber, a diaphragm in said chamber, a fuel inlet anda fuel outlet on the same side of the diaphragm, a valve for controlling said inlet, a support connected with the diaphragm, said sup port having a lateral extension passing beneath the discharge end of the inlet passage, said valve being separate from and supported by said extension, means operating on said diaphragm tending normally to move it in a direction to open said valve, and connecting means adapted to connect said chamber on the opposite side of the diaphragm and the suction side of an engine,
whereby the suction will move the diaphragm in a direction to close the valve.
2. In a device of the character described, a chamber, a diaphragm in said chamber, a fuel inlet and a fuel outlet on the same side of the diaphragm, a valve for controlling said inlet, a support connected with the diaphragm, said support having a lateral extension passing beneath the discharge end of the inlet passage, said valve being separate from and supported by said extension and having a projection extending into an opening in said extension, means operating on said diaphragm tending normally to mov it in a direction to open said valve, and connecting means adapted to connect said chamber on the opposite side of the diaphragm with the suction side of an engine, whereby the suction will move the diaphragm in a direction to close the valve.
