Filed: 1985-11-27
Abstract: PURPOSE:To enable a free-piston type Stirling engine to be easily started by means of a simple starting equipment by causing a pressure fluctuation to take place at the time of starting in a gas spring chamber in the engine. CONSTITUTION:In a free-piston type Stirling engine which is operated by the free vibration of a displacer 11 performing a reciprocating motion in the piston, a gas spring chamber 10, which is compressed and expanded in response to the vertical motion of the displacer 11, is connected to the chamber of a small piston 9, which is driven by a motor, consisting of a stator winding 5 and a rotor 6, provided on the outside of the engine. When the engine is started, only by driving the motor to cause the vertical motion of the small piston 9 to take place, the pressure in the gas spring chamber 10 is fluctuated, and the displacer 11 piston is caused to perform a reciprocating motion, and then, the working gas is caused to reciprocate between the high temperature space 15, a heater 12, a regenerator 13, a cooler 14, and the low temperature space 16 so that the engine is started.

Inventor: KANO SEIJI
IPC: H02K5/04
Filed: 1985-11-25
Abstract: PURPOSE:To obtain a lightweight motor with a supers cooling performance that can be manufactured inexpensively by constituting a stator by sandwiching the core with stator frame partitioned blocks in two-piece housings from both sides. CONSTITUTION:To an annular core fastening fitting 3a to fasten a stator core 2a brought to contact with both sides of the core 2a, ribs for reinforcement 5b and 5b of the truck mounting arm 5 fixed to the truck of a carriage are extendedly provided into an integral construction. Stator frame partitioned blocks 1a and 1b divided into two-piece housings are put over until they come into contact with the outside surface of a fastening fitting 3a. The connecting portion 10 of the partitioned blocks 1a and 1b are connected to the connecting portion 9 of the fastening fitting 3a with bolts 8 to constitute the stator. Thus, the stator frame can be lightweighted that much, and that it excels in cooling performance because it has no portion to cover the outside circumferential surface of the core 2a with. Moreover, as the stator frame has no portion to engage with the core 2a, it is not necessary to machine the engagement portion. On this account, the manhours for machining can be reduced and the manufacturing cost decreased.
