Embodiment Construction

[0037] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0038] according to figure 1 and figure 2 A first embodiment of the invention is shown, figure 1 and figure 2 The Stirling engine E of the present invention is illustrated. Usually used to drive prosthetic legs 1 . The prosthetic leg 1 comprises a prosthesis 2 integral with a socket 2a; the socket 2a is for insertion of the residual leg by the patient. The artificial tibia 4 is flexibly / extendably connected to the lower end of the artificial thigh 2 through the artificial joint, and the foot 5 is connected to the lower end of the artificial tibia 4 .

[0039] The Stirling engine E comprises a purge unit 6 and a control unit 7 . These two parts are mounted on the belt B, which is worn on the waist of the patient. The power cylinder 8 is installed on the prosthetic leg 1 and is located between the prosthetic thigh 2 and the prosthetic shin 4 . The pressure lin...

Abstract

Provided are a Stirling engine and a control unit used therein. The purging unit and the power cylinder can be arranged separately from each other, thereby increasing the degree of freedom in the layout of the Stirling engine. In the case of a separate arrangement of the purging unit and the power cylinder unit, the purging unit compression chamber is connected to the operating chamber of the power unit via a pressure line. A control actuator connected to the purge piston enables the arbitrarily controlled purge piston of the purge unit.

Description

[0001] References to related applications [0002] This application claims priority under 35 USC 119 to Japanese Application No. 2001-071796 filed on March 14, 2001 and Japanese Application No. 2001-075568 filed on March 16, 2001. The entire content of this application is related to this. technical field [0003] The invention relates to a Stirling engine and its control system. The Stirling engine consists of a purging unit and a power cylinder unit, in which a purging piston is slidably embedded in a purging cylinder, thereby dividing the interior of the cylinder into an expansion chamber and a compression chamber In the power cylinder unit, a power piston is slidably embedded in the power cylinder to form an operating chamber, which is connected with the compression chamber in the cylinder. Background technique [0004] The Stirling engine is known in a handbook titled "Car Engineering Series, Vol. 8 'Electric Car, New Type Motor'" (Car Engineering Series, Vol. 8 'Elect...
