K. J. E. HESSELMAN FUEL VALVE Filed Oct. 14
Patented June 17, 1924 UNITED STATES PATENT OFFICE.
FUEL VALVE.
Application filed October 14, 1922. Serial -No; 594,579;
To allwhom it may concern:
Be it known that I, KNUT JONAS Ems HESSELMAN, a citizen of the Kingdom of Sweden, residing at saltsjo'Storan en, Sweden, have invented new and useful mprovements in Fuel Valves, of which the following is a specification. In the type of fuel valves which is opened due to the increased pressure during the die charge stroke of the fuel supply pump, the seat of the fuel valve is subjected to heavy 4 stresses. This is due to the fact that the valve seat must be very narrow in order that the valve may open at a iven moment.
Thus the pressure on the seat will be considerable, making it necessary to build the seat of very hard material and with the very highest accuracy. In well known designs this is very difiicult to obtain as the seat issituated far down in the fuel valve casing or in a member inserted therein.
. This invention relatesparticularly .to that type of fuel valves the opening of which is eflected due to the said increased pressure through the intermediary of an elastic hollow member connected to the valve, as a bellows or the like. The invention is character ized, chiefly, in that the valve seat is provided at the upper edge of a separate memher inserted in the valve casing, the guideway for said valve being arranged belowthe valve body engaging said seat.
In the accompanying drawing, a longitudinal section through a. fuel valve accord- 36 ingvto this invention is shown.
. ith reference to the drawing, the fuel I valve casing 1 is shaped as a sleeve having a fuel inlet as at 2. Inserted in the sleeve 1 at the lowermost end thereof is a plug- 40 shaped member '3 resting with an enlarged portion on a shoulder ,30 formed in the sleeve, and held in place by means of a nut 4; screwed on the lowermost threaded portion .of the member 3 ,and engaging the lowermost end surface of'the casing 1. The
member 3 is formedwith a central fuel passage 5. The lowermost end ofsaid passage is enlarged and threadedinternally to re-- 8 engaging 1 said head 80 being securely maintained in said recess by means of a nut 81, as shown. to The bellows 10 may be of a known design adapted to be operated by the fuel pressure -to open the valve. By placing the valve seat at the uppermost edge .ofthe member 3, the seat'will be readily accessible for inspection and may be readily manufactured with the highest degree of accuracy by grinding it simultaneously with the grinding of the guiding boring 50; The member?) may, if desired, be hardened, on a hardened bushing may be inserted therein. Owing to the fact that the member 3 isconstructed to be inserted from the uppermost end of the valve casing, it will readily be seen, that the pressure within the casing 1 will.tend to maintain the member 3 against the shoulder 30 thereby rendering the tightening eflective.
What I claim is A fuel valve comprising a sleeve shaped casing, a tube in said casing compressible in the longitudinal direction by the fuel pressure within the casing and guided at one end of the latter, a plug-shaped member inserted in the casing at the opposite end thereof, said plug member having a through-extending boring and a valve seat at the inner end of said boring, an extension of said hollow tube engaging said boring to be ided I therein, "a valve body formed integral with said extension to engage said seat, and a' fuel sprayer secured to said plug member at the outer end of said boring,
In testimony whereof I have signed 111 name. I
