A power plant for generating electrical power comprises opposed piston assemblies each at the end of a rack and pinion mechanism conformed to pass through a linear inductor. Thus on each piston firing stroke the linear translation of the rack is used to produce electrical power. This is achieved by an interdigitated magnetic structure attached to each rack. In this manner a linear inductor is utilized to take benefit of each stroke in the course of generating eleetricity. Each pair of opposed pistons includes its own throttle control system, thus allowing for convenient balancing of the total power. The throttle control system operates a mixture mechanism which combines combustion air with fuel and waterto form a charge which is injected into the firing chamber.

A linear magnetic motor/generator (10) uses magnetic flux to provide mechanical motion or electrical energy. The linear magnetic motor/generator (10) includes an axially movable actuator mechanism (12). A permanent magnet mechanism (14) defines a first magnetic flux path (16) which passes through a first end portion (18) of actuator mechanism (12). Another permanent magnet mechanism (20) defines a second magnetic flux path (22) which passes through a second end portion (24) of actuator mechanism (12). A drive coil (26) defines a third magnetic flux path (28) passing through a third central portion (30) of actuator mechanism (12). Drive coil (26) selectively adds magnetic flux to and subtracts magnetic flux from magnetic flux flowing in the first and second magnetic flux paths (16) and (22), respectively, for supplying an axial force to the actuator mechanism (12).

摘要:
An electromechanical transducer apparatus is disclosed and includes a housing. A static portion is substantially immobilized within the housing and includes a magnetic flux generator for generating magnetic flux, a pair of pole pieces for coupling magnetic flux through at least one of a first magnetic circuit and a second magnetic circuit, and a coil disposed to electromagnetically interact with one of the magnetic circuits. The static portion is thermally coupled to the housing via a low thermal resistance path to permit removal of heat. A movable portion includes first and second closing pieces separated from the pole pieces by first and second gaps. The closing pieces are mechanically coupled and supported for reciprocating motion about an equilibrium position which varies the gaps to cause a variation in magnetic reluctance in each of the first and second magnetic circuits.

A return mechanism is achieved which requires only a small force for operation. In one aspect of the present invention, a return mechanism (10) includes: a first spring (1) that acts between an operating section (11) and a working section (12); and a second spring (2) that acts between the operating section (11) and a base (13). A direction in which the second spring acts when the operating section (11) is in a first position is not parallel to a direction in which the second spring (2) acts when the operating section (11) is in a second position. A component which, of a force of the second spring, acts in a direction of motion of the operating section (11) is smaller when the operating section (11) is in the second position than in the first position.
