    Abstract: Elektromagnetski uredaj za regulisanje dovoda struje elektricnom pokretacu motora sa unutrasnjim sagorevanjem, koji obuhvata noseci element (2) na kome su postavljena dva nepokretna kontakta (5, 5a) koji se povezuju sa nekim izvorom napona i sa elektricnim pokretacem, nosac (14) povezan sa pomenutim nosecim elementom (2), a koji obuhvata nepokretan granicnik (8), sklop (17, 18, 19, 21, 24) pomerljiv u odnosu na granicnik (8), a koji je prikljucen na sredisni deo pomerljivog kontakta (22) ciji slobodni krajevi (40) mogu da se sprezu sa nepokretnim kontaktima (5a) da bi regulisali dovod struje u elektromotor pokretaca, i upravljacki elektromagnet (3) koji obuhvata nepokretni namotaj (10) i pripadajuce pokretno jezgro (15), koje se moze pomerati pobudivanjem namotaja (10) od pocetnog polozaja mirovanja do krajnjeg polozaja u kome udara na granicnik (8), pri cemu je na pokretnom jezgru postavljen pomerljiv sklop (17) tako da dovodi krajeve (40) pokretnog kontakta (22) u dodir sa nepokretnim kontaktima (5a) pre no sto dostigne svoj krajnji polozaj, a pomerljivi kontakt (22) moze da se savija kao elasticna greda usled sprezanja sa nepokretnim kontaktima (5a), pri tome je konstrukcija takva da, kada pomerljivo jezgro (15) udari u granicnik (8) nepokretni kontakti (5, 5a) osciluju oko svojih normalnih radnih polozaja, naznacen time, sto je pomerljivi kontakt (22) nacinjen tako da, kada nepokretni kontakti (5, 5a) pocinju da osciluju, njegovi slobodni krajevi (40) prate kretanja nepokretnih kontakata (5, 5a), pri cemu je njegovo ubrzanje (a1) u okviru njegovih sopstvenih vibracija vece od ubrzanja (amax) nepokretnih kontakata (5, 5a), a njegova amplituda (s1) oscilovanja je veca od amplitude (s) oscilovanja nepokretnih kontakata (5, 5a). - Prijava sadrzi jos 3 nezavisna zahteva.

    Abstract: The device comprises two fixed contacts (5, 5a), a movable assembly (17; 18, 19, 21, 24) coupled to the central portion of a movable contact (22) the free ends (40) of which can cooperate with the said fixed contacts (5a), and a control electromagnet (3) comprising a solenoid (10) and a movable core (15) displaceable from an initial rest position (Figure 1) to a final position in which it strikes a stop element (8) carrying with it the movable assembly (17) so as to bring the end (40) of the movable contact (22) against the fixed contacts (5a) before reaching the final position. The movable contact (22) can flex resiliently like a beam under the effect of its engagement with the fixed contacts (5a). When the core (15) strikes the stop element (8), the fixed contacts (5, 5a) oscillate about their normal working positions. The movable contact (22) is made in such a way that, as the fixed contacts (5, 5a) start to oscillate its free ends (40) follow the movements of the fixed contacts (5, 5a), its acceleration (a1) in its own mode of vibration being greater than the acceleration (amax) of the fixed contacts (5, 5a) and its amplitude of oscillation (s1) being greater than the amplitude of oscillation (s) of the fixed contacts (5, 5a).
