6 Claims.

This invention relates to improvements in vaporizing devices and is particularly concerned With devices adapted to vaporize liquid fuel for internal combustion engines, oil burners or the like.

It is an object of the invention to provide a device capable of converting liquid fuel into iinely divided vapor readily capable of combustion whereby utmost energy may be obtained l0, from such fuel.

A further object of the invention is to provide a device which is adapted to vaporize relatively heavy or high boiling motor uids, such as kerosene and fuel oil, without necessity of employing i5 heat to assist or effect such vaporization.

A further object of the invention is to provide a device which, when associated with the suction side of a blower, an intake manifold, or the like, is readily responsive to the suction therefrom v and will feed thereto in predetermined volume liquid fuel inA a finely divided vaporous condition.

Still another object is to provide a vaporizing device having a novel arrangement of air ducts through which air may be drawn into the vaporizing chamber and into the liquid chamber preferably beneath the level of the liquid therein whereby to positively force the liquid/into the vaporizing chamber and whereby to regulate the character or degree of its vaporization.

Another object is to provide a vaporizing devicetional view of'a vaporizing device embodying the principles of the herein invention.

Fig. 2 is a fragmentary section taken along line 2--2 of Fig. land looking in the direction of the arrows.

Fig. 3 is a sectional view taken along line 3'-` 3 of FlgLl and looking in the directionof the arrows.

Figf4 is a sideelevatinal view of thedevicev illustrated in Fig.'1 lshown inas'sociation with the intake manifold 'of an internal *combustionv engine; and

Fig; 5 is afsi'de elevationalview ofA thedevice of Fig. 1` shown liriasrsoci'ation with thev suction side of yablo'werv as for an'oil` burning furnace or the like.

Referring more particularly to the drawings wherein like numerals refer to like parts, a housing indicated generally at A includes at opposite ends thereof an elongated vaporizing compartment I8 and a liquid compartment I2, Packed in 5 vaporizing compartment I0 and extending substantially throughout the length thereof is a mass of steel wool or other equivalent material which is capable of dispersing the liquid into an extremely finely divided vaporous condition during 1 its passage therethrough. T he mass of steel wool I4 or other material having equivalent characf teristics under the conditions herein also operates as a ltering medium for the liquid fuel. Shoulders I6 or other suitable means may be provided inten'or-ly of the vaporizing chamber III to support at opposite ends thereof screens I8, which in turn serve to support and compact therebetween the mass of dispersing and filtering material I4. 20

As clearly shown in Fig. 1, liquid chamber I2 is positioned at the bottom of cylindrical housing A and directly beneath and in open communication with the vaporizing chamber I8'. Liquid is introduced to the chamber I2 through inlet connec- 25 tion 20 and the liquid therein may be maintained at a predetermined level by means of a novel float valve arrangement including the disc oat member 22 which bears upon a lever 24 which in turn pivotally supports and suspends a valve stem 30 26 carrying a valve 28 which is adapted to cooperate with a seat 30 formed in the liquid feed line 20.

Disposed axially of the housing A and extending vaxially throughout the length of the vapor- 36 izing chamber I0 and liquid chamber I2 is an internal iiue indicated generally at 32 carrying at its lower end a yoke member 34 which receives the valve stem 38 of a safety or release valve 38 normally urged ink seated position upon the end 40 -of thefiue 32 by means of a tension spring 40.

Safety valve 38 serves to readilyrelease pressure rresulting `from any backfire or the like whereby chamber I2so`thatthe liquid chamber is dis= posed circumferentially of theilue makes possible the vnovel oat valve arrangement wherein 50, the ringlike iioat V22Imay be'fdisposed annularly f of theexterior wallof the ue 32 'and be guided thereby. Y H i Disposed circumferentially ofthe vhousing Af at the end thereof forming the liquid compartment I2 and the lower vportion of the vaporizing compartment III is a double walled skirt 4I between the walls of which are provided a plurality of pairs of

tubular air ducts

42 and 44 communicating with vapor chamber IIl and liquid chamber I2, respectively. For this purpose, the outer Wall of vaporizng chamber I is suitably apertured as at 46 and the outer wall of liquid chamber I2 is suitably apertured as at 48. It will be noted that the apertures 48 in the wall of the liquid chamber preferably are disposed beneath the normal level of the liquid therein whereby the air draft through the ducts 44 will bubble through the liquid whereby to initiate some breaking up of the liquid when it is drawn into the vaporizng chamber.

The outer ends of the

tubular air ducts

42 and 44 open upwardly of the liquid chamber I2 and preferably terminate in a single plane whereby to be more readily associated with a slide valve in the form of an apertured collar 50 manually rotatable by the projection 52 and supported upon the skirt 4| by means of lugs 54 whereby reciprocal or rotary 'movement thereof may vary registration of the apertures with the free ends of the various pairs of

air ducts

42 and 44 to control the admission of air thereto.

A closure 56 at the upper'end of housing A supports a tubular outlet B for the vaporous products issuing from vaporizng chamber I 0. As clearly shown in Fig. 1, the tubular outlet 58 has a portion 50 thereof telescopically arranged with respect to internal flue 32 whereby to provide a reversely curved flow path for the exiting vapors as indicated by the arrows in Fig. 1. This arrangement provides a Ibarile for the exiting vapors and also oil'sets or removes the vapor outlet from the vaporizing chamber III and associates the vapor outlet with the flue 32 so that in the event of backiire or the like the pressure will be released through operation of safety valve 38 disposed at the opposite end of flue 32 and will not carry into the vaporizng chamber I0. A throttle or feed valve 62 to regulate withdrawal of vapors is disposed internally of tubular outlet 58.

In the operation of the device above described, the outlet end thereof. may be suitably connected to the inlet manifold of an internal combustion engine indicated generally at B in Fig. 4 or to the suction side of a blower as indicated generally at C in Fig. 5 and the liquid inlet end thereof suitably connected to a fuel supply.

Slide `valve 50 may be`adiusted to the extent necessary to control the admission of air to

air ducts

42 and 44 communicating with vaporizng chamber I0 and liquid chamber I2, respectively, and in response to the suction exerted by the intake manifold B or the blower C, predetermined quantities of liquid and air will be drawn into the vaporizng chamber Il! and into the steel wool or other packing material I4 whereby the liquid will be broken up into a finely divided vaporous condition, the vaporous mixture thence passing to the outlet tube 58 and its withdrawal into the manifold B or the blower C regulated by means of throttle valve B2. Valve 30 disposed in liquid inlet 20, being responsive to the liquid level in chamber I2, will function to maintain the liquid in chamber I2 at any desired predetermined level preferably short of lower screen I6 which supports the mass of steel wool or equivalent material I4. y

It will be apparent that if the filtering or dispersing material I4 becomes contaminated or if for other reasons it is desirable to remove the same, closure 56 may be removed from the housing A, upper screen I6 unseated and the mass I4 readily withdrawn and replaced or replenished and the device again assembled by reverse steps. Provision of the steel wool or mass of equivalent material I4 makes it possible tol effect a fine vaporization of relatively heavy fuels on the order of kerosene, fuel oil or the like, without the necessity of applying added heat to effect or assist in effecting vaporization thereof. In this respect the device is simpler in construction and possesses fewer parts than prior devices and has been found to -be extremely. eiiicient in operation.
