Abstract
A device for feed control of valve-controlled internal combustion engines, with the combustion chamber capable of being closed off by an intake valve toward the intake passage, and with a further shutoff element being provided in the intake passage. This further shutoff element is a slotted flat slide valve which is movable in an oscillating manner and cooperates with counter slots. The counter slots are formed by vanes arranged in the housing. The flat slide valve is drivable by a cam.
Claims18
A device utilized with a fuel source and a combustion-air source for feed control of valve-controlled internal combustion engines having at least one cylinder and cylinder head arrangement, each of which has a combustion chamber and a housing attached to said cylinder head and provided with an intake passage and an intake pipe for providing communication between said fuel source and combustion-air source and said combustion chamber, each of said cylinder/cylinder head arrangements also being provided with an intake valve for shutting off communication between said combustion chamber and said intake passage, said device comprising a further shut-off element, in the form of a manifold slotted flat slide valve, for shutting off communication between said combustion chamber and said intake pipe, said slide valve being located in said intake passage and said intake pipe, being movable in an oscillating manner, and cooperating with manifold slot-shaped ports in a portion of said housing located in said intake passage and intake pipe.
A device utilized with a fuel source and a combustion-air source for feed control of valve-controlled internal combustion engines having at least one cylinder and cylinder head arrangement, each of which has a combustion chamber and a housing attached to said cylinder head and provided with an intake passage and an intake pipe for providing communication between said fuel source and combustion air source and said combustion chamber, each of said cylinder/cylinder head arrangements also being provided with an intake valve for shutting off communication between said combustion chamber and said intake passage, said device comprising a further shut-off element, in the form of a manifold slotted flat slide valve, for shutting off communication between said combustion chamber and said intake pipe, a cam and a frame serving as a pushrod associated with said slide valve, said slide valve being located in said intake passage, being movable in an oscillating manner, and cooperating with manifold slot-shaped ports in a portion of said housing located in said intake passage, said cam having substantially the same width as said frame.
A device utilized with a fuel source and a combustion-air source for feed control of valve-controlled internal combustion engines having at least one cylinder and cylinder head arrangement, each of which has a combustion chamber and a housing attached to said cylinder head and provided with an intake passage and an intake pipe for providing communication between said fuel source and combustion air source and said combustion chamber, each of said cylinder/cylinder head arrangements also being provided with an intake valve for shutting off communication between said combustion chamber and said intake passage, said device comprising a further shut-off element, in the form of a manifold slotted flat slide valve, for shutting off communication between said combustion chamber and said intake pipe, a cam and a frame serving as a pushrod associated with said slide valve, said slide valve being located in said intake passage, being movable in an oscillating manner, and cooperating with manifold slot-shaped ports in a portion of said housing located in said intake passage, said frame being provided with two windows, each of which is provided with a pressure spring arranged therein in such a way that said push-rod is in constant positive contact with said cam.
