Abstract

The invention relates to a head (1) of cylinder (2) for a four stroke combustion engine with a valve gear with lifting valves. The head (1) of each cylinder (2) is provided with one main conduit (3), annular shaped orifice (4) leading into the cylinder (2) its axis (5) being situated in the direction of the main axis (6) of cylinder (2) and orifice (4) of main conduit (3), provided with interior valve seat (8) and exterior valve seat (9). Inside the interior valve seat (8) and exterior valve seat (9), in its closed position an annular plate (12) is situated of the sole lifting valve (7) of cylinder (2) provided by at least one stem (11). The main conduit (3) in the head (1) is divided into an inlet conduit (15) and exhaust conduit (16), where the inlet conduit (15) is provided with a valve (17) and/or with a slide valve (18).

Claims

AMENDED CLAIMS[received by the International Bureau on 25 April 1995 (25.04.95); original claims 1-10 replaced by amended claims 1-9 (3 pages)]
1. The head of a four stroke combustion engine with a valve gear with lifting valves, where least one inlet conduit and at least one exhaust conduit situated in head of cylinder joint into a single main conduit, the main conduit has at orifice into cylinder a section in shape of an annulus, the axis of which is placed in the direction of the main axis of cylinder and orifice of main conduit is provided with an interior valve seat and exterior valve seat, in which, in the closed possition, is situated an annular plate of the sole lifting valve in cylinder, d e f i n e d by that the exhaust conduit (16) of combustion engine head (1) is directly interconnected to exhaust branche and provided without any valve and/or slide valve and inlet conduit (15) provided with a valve and/or slide valve (18) , where the size of orifice (4) flow-section corresponding to the sum of flow areas arround and inside annular plate (12) and at the same time ratio of inside diameter d-^v to the outside diameter d2v of annular plate (12) corresponds to the ratio of flow area inside annular plate (12) to flow area outside plate (12) , where the flow areas lies in a plane normal to the main axis (6) of cylinder (2) , the lifting valve (7) is provided with at least one stem (11) and in a space interior valve seat (8) is located a sparking plug and/or an injection nozzle.
2. Cylinder head according to claim 1, d e f i n e d by that the lifting valve (7) which in its closed position is in the sealing surfaces (10) of the interior valve seat (8) and exterior valve seat (9) which are situated on a single flat or conical surface.
3. Cylinder head according to claim 1 or 2, d e f i n e d by that the lifting valve (7) is provided with only one stem (11) placed in axis (5) of main conduit (3) where stem (11) is connected to annular plate (12) by at least one bridge (13) and is provided with individual sealing (14) in head (1) of the combustion engine.
4. Cylinder head according to claim 1 or 2, d e f i n e d by that the lifting valve (7) is provided by two stems (11) situated in orifice (4) of main conduit (3) , where stems (11) are on annular plate (12) placed at 180°, while all stems (11) in head (1) are situated in one row behind each other.
5. Cylinder head according to any above mentioned claims d e f i n e d by that valve (17) in the inlet conduit (15) of combustion engine head (1) is of automatic and non-return valve construction.
6. Cylinder head according to any above mentioned claims, d e f i n e d by that in orifice (4) of main conduit (3) is an injector (21) for low pressure fuel injection delivery of fuel directly into the space of cylinder (2) .
7. Cylinder head according to any above mentioned claims, d e f i n e d by exhaust conduit (16) beeing terminated on opposite side of head (1) than inlet conduit (15) while axis of inlet conduit (15) and/or axis of exhaust conduit (16) do not cross axis (6) of cylinder (2) .
8. Cylinder head according to any claim 1 to 6, d e f i n e d by inlet conduit (15) and exhaust conduit (16) beeing terminated on one side of head (1) while axis of inlet conduit (15) and/or axis of exhaust conduit (16) do not cross axis (6) of cylinder (2) .
9. Cylinder head according to any above mentioned claims, d e f i n e d by exhaust branches of each engine cylinder (2) are interconnection with ejector joints.
