Abstract
The present invention relates to a compression release valve (10;10';10';10'') for a combustion piston engine, said valve including a housing (12;12';12'') with a chamber (20;20';20'') having a passage (24;24';24'') in direct connection with the combustion chamber (22;22') of the engine and outlet means (26;26';26'') connected to the atmosphere or a space separated from the combustion chamber (22;22'). The compression release valve according to the present invention is characterized by being fully automatic. The function of the compression release valve is based on the fact that the valve includes elements of material having different coefficients of thermal expansion.
