Title: Stirling engine
Inventor: YAMASHITA TAKESHI
IPC: F02G1/043
Filed: 1987-03-31
Abstract: PURPOSE:To obtain a stirling engine with a small installation space and easy for assembly and maintenance by forming a buffer tank communicated between piston back chambers in a cylinder in a crank chamber and making the buffer tank unnecessary or small sized. CONSTITUTION:When an expansion piston 6 and a compression piston 7 are pushed down respectively, the operating gas or air in piston back spaces 16, 17 is compressed. At this time, the piston back space 16 is communicated to a buffer tank 20 via communicating holes 18, 19. The piston back space 17 is also communicated to the buffer tank 20 via communicating holes 21, 22, thus the compressed operating gas or air escapes to the buffer tank 20. Thereby, the resistance of the pistons 6, 7 during the reciprocating motion is decreased. since the buffer tank 20 is provided in a crank chamber 8, the installation space of an engine can be small, and the assembly and maintenance work is facilitated.
