  • Circlips
    Patent number: 6296417
    Abstract: A circlip (8) comprises a band of material forming an incomplete ring, and has curved bearing surfaces (10, 11) at opposite ends of the major transverse dimension of the band. The major transverse dimension is generally oriented at less than 90°, and preferably a small acute angle &agr;, to the central axis A of the ring in the unstressed state of the circlip (8).

  • Stirling engines
    Patent number: 5345765
    Abstract: A stirling engine with mechanical output through a main shaft (71) has piston(s) (44) reciprocable in cylinder bore(s) (41). Each piston is guided on a fixed piston guide (52) which extends into but not through the piston. This guidance holds the piston clear of mechanical contact with the cylinder bore (41). A separate seal is provided between the piston and the bore. Internal guidance of the piston permits a guidance arrangement where clearances change very little or not at all with changes in temperature of the engine.

  • Stirling engines
    Patent number: 5309715
    Abstract: A Stirling engine with mechanical output through a crankshaft (57) has piston(s) (42) reciprocable in cylinder bore(s) (41). The piston to crankshaft connection includes a lever arm (74) on pivot pin (77) and a connecting rod (75). The lever arm passes through opening (76) which is sealed from the engine crankcase by an annular seal member (94) engaged against part spherical seat (91) on the lever arm by gas pressure and by a spring washer (65).
