Abstract
880,154. Reciprocating generators. JARRET, J. H., and JARRET, J. M. B. Dec. 17, 1957 [Dec. 18, 1956], No. 39279/57. Class 35. [Also in Group XXVII] A free-piston I.C. engine comprises in the Fig. 1 embodiment a piston 6 rigidly connected to magnetic elements 14a, 14b reciprocable in gaps in the second and third parts 11a, 11b of a three-part magnetic circuit the first part 12 of which carries an output coil 17 in which is induced by reciprocation of the elements when the parts 11a, 11b are excited by coils 15a, 15b a voltage, which controls an air or fuel supply valve 21, Fig. 3. The coils 15a, 15b are excited by a D .C . source 16 and are so wound and connected in either series or parallel as to generate mutually opposed fluxes in the first part 12. The block C in Fig. 1 may be the solenoid device of- Fig. 3 wherein the output voltage of the coil 17 is fed to winding terminals 23 to control the position of a spring- biased magnetic core 25 connected by a linkage 26, 27 to the valve 21 which is disposed in the air intake conduit 22 of the fuel supply system, and the arrangement provides that the frequency of the output voltage is used to maintain substantially constant the reciprocation rate of the piston 6. In a modification, Fig. 4, not shown, the output voltage is fed via an electronic variable pulse generator to an electromagnet controlling the needle valve of a fuel injector. In the other embodiment, Fig. 5, the engine comprises two conjugate pistons 37, 38 each connected to respective elements 47, 48 of two electromagnetic systems whose output coils 58a, 58b are interconnected at 59, 60 to cause the two pistons to reciprocate in synchronism. Rigid transmission rods 41, 42 secured to the pistons may drive a load such as a compressor or a mechanical energy converter. The output voltage may also charge a storage battery which may be the source 16. The invention may be combined with the system disclosed in Specification 764,495 which is referred to.
