Abstract:
1. Valve arrangement in a combustion engine for controlling inlet and outlet of gas mixtures, comprising a valve ( 1 ) slidably arranged within a housing ( 2 ) in a cylinder head ( 3 ) of the combustion engine, said valve ( 1 ) including a valve plate ( 10 ) and a stem like portion ( 1 A, 1 B), said stem like portion ( 1 A, 1 B) having an upper portion ( 1 B) fixedly attached with its lower end to, a lower portion ( 1 A), said lower portion ( 1 A) having said valve plate ( 10 ) attached thereto which valve plate interacts with a valve seat ( 30 ) to allow for outlet and inlet of gases respectively, a valve control mechanism ( 5 , 6 ) to control the movement and/or position of said valve ( 1 ), wherein said upper portion ( 1 B) forms a hollow annular body ( 19 ) extending coaxially with the extension of said stem like portion to allow for said gases to be transported through the valve ( 1 ) in a channel within and formed in said annular body ( 19 ), the valve plate ( 10 ) is connected to the lower portion ( 1 A) to form a gap between the valve plate ( 10 ) and the upper portion ( 1 B) to allow for said gases to be transported past the valve plate into or out from the inside ( 190 ) of said hollow annular body ( 19 ), characterised in that the upper end ( 18 ) of said annular body ( 19 ) is open and said hollow annular body ( 19 ) at its outer side ( 191 ) is arranged with at least one first interacting device ( 14 , 15 ) arranged to interact with at least one second interacting device ( 53 , 54 ) of the valve control mechanism ( 5 , 6 ) to facilitate said movement and positioning.
