Shaft engine
First Claim
1. A shaft engine comprising a cylinder having at least one spark plug and at least one raised air chamber, each raised air chamber having an extension tube extending outwardly from said cylinder, a piston moved up and down in said cylinder by means of the ignition of a fuel gas introduced into said cylinder, the ignition being accomplished by said spark plug, at least one cylinder shaft respectively received in said at least one raised air chamber and the corresponding extension tube, said cylinder shaft being reciprocated by said piston to move a crank shaft outside said cylinder, each cylinder shaft being peripherally mounted with seal rings to seal the gap between the extension tube in which it is mounted and said cylinder shaft having a longitudinal air passage which communicates, as the piston reciprocates, with the raised air chamber for exhausting gas from said cylinder to the surrounding atmosphere.
