Description
Filed Dec. 16, 1929 Z lNl/E/V TOR Z. v Q ZT I Patented Feb, 17, 1931 v UNITED STATES PATENT arms SYDNEY SLATER GUY, or WOLVERHAMP'ION, ENGLAND;
INTERNAL-COMBUSTION ENGINE Application filed December 16, 1329, Serial No. 414,407, and in Great BritainvFebruary 27, 1929. i
This invention relates to internal combustion engines and more particularly to the kind in which the joint between the cylinder and the, detachable cylinder head orcover lies in a plane which. is obliquely arranged with respect to the cylinder axis, and in which the valves are arranged at the highest side ofthe cylinder with their axes inclined to that of the latter and to said plane.
It is found that with the valves in this posidegree of turbulence in the charge of explosive mixture as it enters the combustion chamber than is believed to take place in the engine as at present constructed.
For the purposes of thepresent invention the'shape of the cylinder heador cover is such that when in position on the cylinder the clearance between the inner face of the head and the side of the cylinder bore adjacent the valves is always less than the distance meas ured from the top'of the valve head to the root of the radiused portion of the same where it joins the valve stem. The formation of the said head is also such as to cause considerable turbulence of the explosive charge as it enters the combustion chamber.
In order that the invention may be clearly understood and readily carried into practical effect reference is made .in. describing the same to the accompanying drawing which 40 shows a vertical sectional view of a cylinder head embodying the present invention.
In'the construction shown it will be observed that the detachable head or cover a of conical formation on its inner face 6', the perimeter of the cone being of such dimensions as to bring therounded apex 0 thereof sufliciently close to the valve side of the cylinder d as to prevent the valve head, 6 in the event of fracture, from falling into the cylinder. The clearance f'between the apex of face of substantially conical shape in vertical the cone andthe side of the cylinder bore to which itpoints, is always less than the distance X measured from the top ofthe valve head to the root of the radiused portion of the same where it oints the valve stem, it be ing well known from long experience that if a valve breaks it usually does so somewhere about the dotted line g, that is to say, across the minimum section which ismost exposed to the flame and hot gases issuing through the exhaust port.
This pronouncedconical formation of the cylinder head produces, asshown, a combustion chamber of a shape especially favorable to the promotion of turbulence in the recon 3 mg charge of explosive mixture and as a consequence causes a higher degree of homogeneity of the mixture at the time of firing. That part b of the conical surface facing the valve ports may, as shown, be of more or less concave shape whilst'the part b which faces the cylinder bore can be approximately parallel with the top of the piston.
The cylinder head which is preferably cored for water cooling purposes, may, as shown, be cast in one piece to the desired shape or, alternatively, the conical portion thereof, may be a separate plate secured to the head in any suitablemanner.
I claim: V i i 1. .In internal combustion engines, a cylinder block having an upwardly and outwardly inclined valve seat at one side, poppet valve adapted to take a seating in said valve seat and having a radiused head, and a cylinder cover having a portion of its inner face directed towardsthe side of the cylinder bore adjacent the said valve seat and'of such dimensions as to leave-a clearance less than the distance measured from the top of the valve head to the root of the radiused portion of the same. V
2. In internal combustion engines a cylinder block having aninclined upper end and valve seat at one side inclined in the same direction,.poppet valve adaptedto take a seating in said valve seat and having a radiused head, and a cylinder headhaving its inner section with the apex thereof directed to-- wards the side of the cylinder bore adjacent said valve seat andwith a clearance less than the distance measured from the top of the valve head to the root of the radiused portion 1 of the same.
i In testimony whereof, I have signed my name to this specification at Wolverhampton, England, this 19th day of November, 1929.
