<p>PURPOSE: To simplify structure and actions and to improve durability by respec tively slidably containing plural pistons in plural cylinders, connecting each pistons and actuating them corresponding to 2 strokes of 4 cyclic strokes. CONSTITUTION: Plural cylinders 1 having supply holes 9 and discharge holes 10 contain plural pistons 2 therein that are slidable in the cylinders. While making the top end of the piston 2 contact with a ring 17, an annular shaft 16 and an ignition plug 11 are arranged in the piston 2. The lower end of the piston 2 is connected to a common shaft 3, and is fixed by a nut 4 and a guide 5. Furthermore, the common shaft 3 is slidably contained in a gear 7 through a guide 6, and the gear 7 is engaged with a gear 8 that rotates in a bearing 15. By this constitution, the piston 2 is actuated corresponding to two strokes of 4 cyclic strokes. The structure and actions are simplified and durability is improved.</p> |
