Title: Rod seal device for stirling engine
Inventor: KATSUTA HIROYUKI
IPC: F02G1/053
Filed: 1989-09-29
Abstract: PURPOSE:To reduce an amount of consumption oil and to prevent reduction of an output by providing a relief valve which is located in a communicating passage for intercommunicating an oil pump and a closed space and maintains the delivery pressure of the oil pump at a given value. CONSTITUTION:An oil pump 27 is mounted to the one end of a crank shaft 17. The oil pump 27 feeds a delivery pressure to a closed space 23 through a crank case 16, an expansion cylinder 11, and a communicating passage 28 formed in an intermediate member 18. A relief valve 29 to maintain the delivery pressure of the oil pump 27, fed in the closed space 23, at a given value is located in the communicating passage 28. This constitution always increases a pressure in the closed space 23 to a value higher than a pressure in an intermediate chamber 30. Thereby, rise of oil from the crank shaft side 17 to the working piston 12 side can be prevented.

Inventor: UENO YOSHIYUKI
IPC: F16C33/14
Filed: 1985-11-15
Abstract: PURPOSE:To enable dynamic pressure generating surface shape to be efficiently transferred to a separate member surface by using the dynamic pressure generating surface produced by prior art with high precision for master cam. CONSTITUTION:To work a work 6 attached to a master cam 1, a cylindrical working surface of a tool 8 rotating in the direction of arrow f is adapted to coincide with the radial direction of an annular work and then the tool 8 is fed in the work 6 by a predetermined amount. Next, when the master cam 1 is rotated in the direction of arrow e about the axis 20 by a handle 9, the cam surface 2 contacting a fixed contact point 4 is moved to vary the height of the work according to the respective vertical positions of the cam surface 2. Since here the height of working surface of the tool 8 is not changed, the shape of the cam surface 2 is transferred to the worked surface of the work 6.
