Patent number: 10240822Abstract: A thermoacoustic heating device capable of effectively utilizing streaming, and including a prime mover in a first pipeline that forms a loop line, and a heating device in a second pipeline that forms another loop line. The first and second pipelines are connected to each other via a branch pipeline. A branch pipeline on the prime mover side and the second pipeline on the heating device side are positioned adjacent to each other, and a low-temperature side heat exchanger of the heating device is integrally formed with or held in contact with the branch pipeline on the prime mover side.Type: GrantFiled: October 17, 2014Date of Patent: March 26, 2019Assignee: ISUZU MOTORS LIMITEDInventors: Shou Ozaki, Yasushi Yamamoto

Patent number: 9371798Abstract: A free-piston type stirling engine 1 includes a power piston 30 which partitions the inside of a case 2 into a work space 80 and a bounce space 90, a displacer 40, a communication hole 32 provided in the power piston 30, a displacer rod 41 extending from the displacer 40 and passing through the communication hole 32, a first displacer supporting spring 50 elastically supporting the displacer rod 41 at its proximal end, and a second displacer supporting spring 60 elastically supporting the displacer rod 41 at its distal end. The power piston 30 and the displacer 40 reciprocate along a central axis X of the case 2 with a phase difference therebetween by expansion and compression of a working gas in the work space 80, and bias forces of the first displacer supporting spring 50 and the second displacer supporting spring 60 restrict tilting of the displacer 40 and the displacer rod 41 with respect to the central axis X.Type: GrantFiled: September 13, 2012Date of Patent: June 21, 2016Assignee: ISUZU MOTORS LIMITEDInventors: Shou Ozaki, Yasushi Yamamoto, Hirotsugu Yabe
