ABSTRACT:
The apparatus includes a casing, a cylinder head, a chamber sleeve tube to form a combustion chamber, a cylinder and a drive piston. An isolating element is mounted on the chamber sleeve tube so as, when the apparatus is opened, to isolate the space formed between the anterior part of the chamber sleeve tube and the casing from the combustion chamber. A bellows is provided for ducting the cooling and venting fresh air directly towards the chamber.
