摘要： PURPOSE:To promote the reduction of vibration, by detecting a change of torque of an engine and generating torque, which acts suppressing vibration so as to reduce the change of torque, by controlling an actuator to be driven through the result of the detection of the change of torque. CONSTITUTION:A device, which detects a change of pressure in a cylinder chamber by a pressure sensor 19a, obtains a level of changing torque and its generation timing by a detection value of the change of pressure. A signal of this pressure, which is amplified by a pressure gage 20a to an electric signal of predetermined voltage level, is input to a control circuit 21. The control circuit 21 converts this signal by a predetermined control rule into a signal, having a phase and a gain necessary for reducing a change of torque in a Stirling engine 50, to be output to a driving circuit 22. And the driving circuit 22 supplies driving power to an actuator 18 generating vibration suppressing torque for negating the change of torque. Here the changing torque and the vibration suppressing torque generate their phase reversely to each other so that vibration decreases very smaller.

摘要： PURPOSE:To suppress the contamination of working gas and suppress the impact noise by the simple constitution by directly connecting a compression space and a buffer space which are partitioned by a reciprocating piston through a connecting circuit and installing a check valve in series with a purifying chamber, into the connecting circuit. CONSTITUTION:When a crankshaft 2 is revolved by an electric motor 1, a piston 5 moves in reciprocation in a cylinder 6, and a compression space 12 repeats compression and expansion. When the gas pressure in the compression space 12 lowers under the gas pressure in a buffer space 13, gas is introduced into the compression space 12 from the buffer space 13 through a check valve 15, passing through a connecting circuit 14 for directly connecting the both spaces. Therefore, the gas stream forms an unidirectional circuit, and aspiration action is not generated between the both spaces. Further, the gas which is formed by the slidable movements of a piston ring 7 and a cylinder 6 and contaminated by the abrasion powders which drop into the buffer space 13 and float is purified in a purifying chamber 16 formed in the connecting circuit 14.

摘要： PURPOSE:To prevent blow-through due to the overlapping of abutments by providing inner rings with projections on the inner circumferential side of piston ring grooves, and engagedly setting the abutments of upper and lower plain rings being provided on the outer circumference thereof with said projections. CONSTITUTION:Ring grooves are provided on the side surfaces of a displacer piston 4 and a power piston 5 in a Stirling engine. On the innermost circumference of these ring grooves, tension rings 8 are provided, and on the outside thereof inner rings 7 provided with projections 13a and 13b are arranged. On the outer circumference of each of these inner rings 7, an upper plain ring 6a and a lower plain ring 6b are arranged, and the abutment of each ring is engagedly set in the position where the abutment is dislocated from the position of the projections 13a and 13b of the inner ring 7. Thus, even if the whole ring turns, the abutments do not overlap, and accordingly blow-through can be prevented.

摘要： PURPOSE:To prevent the bypassing flow of a gas from the peripheral edge of sheets of wire gauze and improve regenerating efficiency by covering the peripheral edge of said sheets of wire gauze of a regenerator unit which is formed by laminating plural sheets of wire gauze, with sintered metal, etc. and fitting said unit into a body. CONSTITUTION:Plural sheets of doughnut-form wire gauze 7 are laminated and their peripheral edges are covered by sintered metal 8 etc., to form a regenerator unit 9. This regenerator unit 9 is fitted into a fitting part provided in a body, as a heat exchanger for a Stirling engine, etc. By this construction, the non-fixed form part on the peripheral edge of the sheets of wire gauze can be neatly arranged, and a gas can be prevented from escaping from a non-fixed form part, improving regenerating efficiency and heat exchanging efficiency.

摘要： PURPOSE:To uniformalize thermal stress and improve heat conductivity by providing an annular clearance around an expansion chamber at the upper portion cylinder of of a stirling engine to provide a operative gas chamber. CONSTITUTION:An outside head 15 is provided on the outer periphery of a cylinder 16 constituting an expansion chamber 1a of a stirling engine through a fine annular clearance 18. The expansion chamber 1a communicates to the annular clearance 18 through a gas path of a heater tube constituted from an inner pipe 17b and an outer pipe 17a. The annular clearance 18 communicates to a regenerator 5. Since the cylinder 16 receives heat of an outside combustion chamber through the annular clearance 18, thermal stress is uniformalized and heat conductivity is improved since the cylinder receives heat on the whole surface.

摘要： PURPOSE:To prevent oil from entering into a cylinder, by separating oil contained in working gas circulating between a reaction chamber for a power piston and a crank casing, in a Stirling engine, with the use of a filter, and by pumping out oil with the use of an oil feed pump, together with oil in a distance space. CONSTITUTION:In a Stirling engine, a heater pipe 2 and a cooler pipe 4 which are connected through a regenerator 3 are continuously heated and cooled, respectively, and therefore, a gas feed piston 5 and a power piston 7 are reciprocated with a phase difference therebetween which is regulated by a crank shaft 19. In this arrangement, a gas-oil separating filter 100 is disposed in a communication pipe 12 communicating the inside of the crank casing 9 with the power piston reaction chamber 10. Further, each of the oil reserving section 100b of the filter 100, the bottom section of the crank casing 9 and the bottom section of a distance space 11 and the suction port of an oil feed pump 23 are connected together through pipes 29, 24, 30 incorporating valves 27, 26, 28 respectively, so that oil in these section may be pumped out with suitable timing.
