Title:
RECIPROCATION TYPE COMBUSTION ACTUATOR
Document Type and Number:
Japanese Patent JPS55104527
Kind Code:
A
Abstract:

PURPOSE: To provide a combustion actuator, compact, light, easy to use and strong, by igniting and combusting fuel exuded and evaporated in a combustion chamber, and driving a piston as well as a fuel pump through pressure rise caused by the combustion of fuel.

CONSTITUTION: When combustible state is developed in combustion chamber 8 with fuel like alcohol evaporated from the surface of fuel exuding, porous sleeve 48 being mixed into the air in combustion chamber 8, ignition switch is turned ON for igniting and combusting evaporated fuel by means of ignition plug 54. Resultantly, piston 3 is moved to the right in the drawing against the force of spring 26 through pressure rise in combustion chamber 8, so that air in compression chamber 23 is compressed. At the same time, bellows 18 in work chamber 15 communicated to combustion chamber 8 via port 13 and inner pressure chamber 11 is expanded and effects external work. Further, fuel pump 29 is operated by means of pistons 32, 33. Subsequently, when exhaust valve 58 is opened by energizing electromagnet 64, pressure in combustion chamber 8 drops so that pistons 3 and others return to their original position.
