Cycle-controlled sliding-valve in a heating-chamber combustion engine
First Claim
1. A cycle controlled sliding valve in a heating chamber combustion engine, comprising:
- a housing;
a cylinder defined within said housing;
a piston disposed for movement within said cylinder;
a piston-extension disposed for movement within said cylinder;
a connecting rod having an end pivotally connected to said piston;
a pinion carried by said end of said connecting rod;
a rack positioned within said cylinder and slidable therein, said pinion engaging said rack, and said rack engaging said piston-extension;
a heating chamber;
a path within said housing in communication with said heating chamber; and
an opening within said piston-extension positioned such that said path and said opening are aligned, thereby connecting the cylinder and the heating chamber, at least at some point during a working cycle of said piston,whereby said piston and piston-extension are capable of moving axially within said cylinder in a reciprocal manner during the working cycle of said piston, and said piston-extension is capable of moving axially within said cylinder relative to said piston as said connecting rod swings and causes said pinion to move the rack axially within said cylinder, said rack causing said piston-extension to move axially relative to said piston.

Abstract
A cycle controlled sliding valve in a heating chamber combustion engine is provided. The valve includes a piston disposed for reciprocal movement within a cylinder, a piston-extension disposed for movement within the cylinder, a connecting rod connected to the piston, a pinion carried by the connecting rod, and a rack engaged by the pinion. The rack engages the piston-extension such that the latter is capable of movement in the axial direction of the cylinder away from or towards the piston. Such movement is caused by the swinging of the connecting rod due to crankshaft rotation. A path is provided within the cylinder walls which leads to the heating chamber. When an opening in the piston-extension is aligned therewith, communication is established between the cylinder and the heating chamber. In operation, the path leading to the heating chamber will open later during the up-stroke and will close later during the down-stroke.

7. A cycle controlled sliding valve in a heating chamber combustion engine, comprising:
-
a housing; a cylinder defined within said housing; a piston disposed for movement within said cylinder; first and second opposing piston-extensions disposed for movement within said cylinder; a connecting rod having an end pivotally connected to said piston; a pinion carried by said end of said connecting rod; first and second racks positioned within said cylinder and slidable therein, said pinion engaging each of said racks, said first rack engaging said first piston-extension and said second rack engaging said second piston-extension; a heating chamber; first and second paths within said housing, both paths being in communication with said heating chamber, said first path being closable by said first piston-extension and said second path being closable by said second piston-extension; a first opening within said first piston extension positioned such that said first opening and said first path are aligned, thereby connecting the cylinder and the heating chamber, at least at some point during a working cycle of said piston; and a second opening within said second piston extension positioned such that said second opening and said second path are aligned, thereby connecting the cylinder and the heating chamber, at least at some point during a working cycle of said piston, whereby said piston and said piston-extensions are capable of moving axially within said cylinder in a reciprocal manner during the working cycle of said piston, and said piston-extensions are capable of moving axially within said cylinder relative to said piston as said connecting rod swings and causes said piston to move said racks axially within said cylinder, said racks causing said piston-extensions to move axially relative to said piston. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
