Abstract:
In a gas engine having a crankcase, at least two cylinder/cylinder-head units, each having a combustion chamber, and a flywheel at one end of the engine, the combination comprising:a manifold on the end of said engine opposite said one end, including first and second ducts for delivering an air-gas mixture to said combustion chambers, respectively, said ducts extending, respectively, from said laterally opposite sides of said manifold to a side of said manifold adapted for connection to said cylinder/cylinder-head units,first and second parallel vertical holes in said manifold intersecting said first and second ducts, respectively, adjacent said side of said manifold adapted for connection to said cylinder/cylinder-head units anda roller shaped rotary slide valve in each of said ducts including a tubular flow control element rotatably mounted in each of said first and second vertical holes in intersecting relation to said ducts, respectively,each of said flow control elements including a plurality of passageways therethrough transverse to the vertical axis of rotation of said flow control element through which said air-gas mixture flows to the associated one of said combustion chambers, said flow control elements being operable upon rotation to govern the quantity of air-gas mixture delivered, respectively, to said combustion chambers, whereby engine speed is controlled; said passageways in each of said flow control elements being parallel to one another and spaced vertically from one another in the direction of said axis of rotation of the associated flow control element.
