UNITED STATES EDWARD J. STEELE, OF DES MOINES, IOWA.
VALVE.
Application filed December 8, 1921.
This invention relates to a poppet or lift valve and particularly one of the type used as inlet and exhaust valves in an internal combustion engine for vehicle propulsion.
An important object is to provide a construction in which the valve will have a tight seat, be free from and unali'ected by carbon deposits, whereby better compres sion within the cylinder is attained resulting in greater power and even operation of the engine or motor, a saving secured in fuel and present day valve trouble eliminated.
Another object is to provide such a valve with a skirt depending from the usual disk having a conical exterior wall cooperating with a similarly shaped seat and having openings through said wall to provide a plurality of surfaces or edges designed to scrape the seat to relieve it of carbon.
Additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating one practical embodiment.
in said drawings Figure 1 is a vertical sectional view through a valve and its cage constructed in accordance with my invention;
Figure 2 is a side elevation of the valve alone;
Figure 3 is an inverted plan view of the valve alone, and
Figure 4 is a detail side elevation of a modified form of valve.
Like reference characters designate like or similar parts in the diiferent views.
In carrying the invention into practice, a suitable seat as at 10 is provided which may be formed on a-valve cage 11 at its inner wall. Such provision of the seat is to be taken as conventional, since the illustration shown it is for an overhead valve, While it is just as capable of use in internal valves or other arrangement.
The valve which forms the essential feature of the invention, has a head at 12 mounted on a stem 13 slidable axially of the Serial No. 520,919
cage 11 and against the tension of the spring 14.
Extending downwardly from the head 12 is a flange or skirt 15, preferably being annular and having its outer surface inclined or substantially conical similarly to the seat 10. Suitable ports, which may be rectangular, as suggested at 16, may be provided through the skirt 15 to facilitate inlet or escape of gases, according to the use of the valve.
It will be noted that above and below the ports 16, that is at the upper and the lower edge of the skirt, the same is offset or laterally enlarged to provide rings at 17, which in practice serves to scrape any deposit of carbon from the wall or seat 10.
In use, as the valve slides against the tension of the spring 1% the seat, the rings, particularly the lower edges of the rings 17 engage and scrape the seat 10 thus effectively removing carbon which may have deposited thereon and preventing such a deposit of carbon as will interfere with effective operation of the engine.
It is to be understood that changes may be resorted to. For instance as shown in Figure 5, the openings or ports equivalent to those at 16, are round and designated 18. The other reference numerals of the preceding form apply and have been used in the drawing.
Having thus described as my invention, what I claim is:
A valve having a rigid head disposed at one end thereof, a skirt depending rigidly from said end, scraper rings in longitudinally spaced relation projecting laterally from said skirt having their marginal walls beveled and adapted to directly engage the valve seat so that their facing edges will scrape the valve seat, and the portion of the skirt between said rings being imperforate and having its outer surface disposed inwardly of and disalined with respect to the outer surfaces of the rings.
In testimony whereof I affix my signature.
EDTVARD J. STEELE.
