This invention relates to the inlet valves 8e 'Such bafile or raised portion may be hollowed internal combustion engines, and has for its object to provide improved means for 1ncreasing the turbulence within the engine cyl- 1 inder or cylinders during and. after admission through the said valves.
It is known to provide a projecting wall which extends partly around the'edge of one side of an inlet valve, such wall being within 10 the valveway so that it obstructs the flow through the valveway at its side of the valve and increases turbulence in the engine cylinder.
In accordance with our invention, the means which obstruct the throughway at one side of an inlet valve consist of a raised platform-like partwhich extends inwards from the valve edge to the valve stem so as to provide a directing path across the valveback to the part of the valve edge where the air or charge can issue into the engine. The inlet branch leading to the valve is so disposed as to direct the charge over the said platform to the other side-of the valve, and the clearance s ace around the valve and in the cylinder ore is made to increase from adjacent to the part of the valve where the said plat form is situated so that increased clearance is provided where the air or charge issues so through the valve.
Referring to the accompanying sheet of explanatory drawings Figure 1 is a sectional elevation through an engine cylinder block on the line A B C of Figure 2 and through the cylinder head on the A B D of Figure 2, the valve being shown in elevation.
Figure 2-is a plan view of the cylinder block with the valve shown in position and 40 the direction of the inlet branch leading to said valve being indicated.
Figure 3 is a sectional view of the valve on the line D B E of Figure 2.
v The same reference letters in the three views indicate the same parts.
The inlet valve a has a bafile 12 arranged upon the back thereof which extends round a portion of the valve and inwards towards the valve stem 0 so as to provide a raised portion at one side of the back of the alve.
out at d by'machiningto, reduce the wei ht of the valve as shown in Figures lan 3. The axial depth of the bafiie b is greaterthan the stroke of the valve so that no throughway is ever available at the side of the. valve where the baflie is situated. The inlet branch 0 which leads to the inlet valve (1 is so directed "only pass in a forwarddirection into the cylinder to produce the swirling motion and can not pass therein insuch' a wa as to oppose or retard the swirling airor c arge.
Toprovide a large area around the valve 1 for the passage of air or the charge intothe cylinder 9 in the desired direction, we make the clearancespaceh in the c linder bore around the valve of .excentric ormation as shown in Figure 2, the space graduallyin creasing from adjacent to the part of the valve where the baflle b is situated and being completed at i .in a direction tangential to the cylinder bore. Such shapingof the clearance space also assists in the productionof turbulence during the period of admission,
the turbulencecontinuing during compression. 1 e I i We find thatthe provision of a raised platform like. part b attheback of one side of the valve serves in an effective mannerto direct the incoming air orcharge to the unshielded or unbafiled side of the valve, whilst the, dis- The baflle may, if, desired, b seated 'to the rear of the valve insteadof'being made integrally therewith.
Claims 1. An inlet valve of an internal combustion engine having a raised platform like part at one side of the back of the valve in order to provide a permanent closure for that side of the valve throughway and to direct the incoming air or charge to the unshielded or unbafiled side of the valve.
2. The combination with an inlet valve as claimed in claim 1, of a clearance s ace around the valve in the engine cylinder ore which increases from adjacent to the shielded side of the valve.
3. Air or charge inlet arrangements ofeinternal combustion engines comprising an ini let valve havin a hollow raised platformlike part formed integrally therewith at one side of the back of the valve, an inlet branch directing the incoming air or charge to the other side of the back of the valve, and a clearance space in the engine cylinder bore of excentric shape relatively to the valve, such space increasing from adjacent to the platform side of the valve and terminating with its wall tangential to the cylinder wall.
4. Air or charge inletarrangements of internal combustion engines, comprising an inlet valve having shielding means thereon for obstructing the flow through the valveway at one side of the valve when the latter is opened,
and a clearance space in the engine cylinder bore around a portion of the valve periphery, such space increasing from adjacent to the shielded side of the valve.
5. Air or charge inlet arrangements of internal combustion engines comprising the combination with a cylinder of the engine of an inlet valve disposed partly in the cylinder bore and partly in a pocket or clearance space in the cylinder wall, a projecting shield at one side of the back of the valve obstructing the flow through the valveway at one side of the valve when the latter is opened, the said pocket being of excentric form with relation to the valve and providing a gradually increasing space from adjacent to the said shield.
6. Air or charge inlet arrangements of internal combustion. engines comprising the combination with a cylinder of the engine of an inlet valve dis osed partly in the cylinder bore and part y in a pocket or clearance space in\the c linder wall a projecting shield at one side of the back 0% the valve, the said pocket being of excentric form with relation to the valve and providing a gradually increasing space from adjacent to the shield, the pocket terminating with its wall tangential to the engine cylinder wall.
In testimony whereof we have signed our names to this s cification.
