Abstract

Il dispositivo comprende un programmatore (P) includente una camma principale (CP) la cui rotazione a scatti è controllata da un nottolino di passo (N), e un organo di arresto (L) atto ad assumere una posizione di sblocco ed una posizione di blocco in cui consente e, rispettivamente, impedisce l'impegno del nottolino di passo (N) con la camma principale (CP). All'organo di arresto (L) è associato un dispositivo elettromagnetico (E) con una bobina (B), un nucleo suscettibile di trattenere l'organo di arresto in una di dette posizioni quando la bobina (B) viene eccitata. Il programmatore (P) comprende mezzi (21) atti a disporre il nucleo mobile (M) presso il nucleo fisso in una condizione di eccitazione della bobina (B), per cui quest'ultima è dimensionata in modo da sviluppare soltanto la forza sufficiente a trattenere il nucleo mobile (M) presso il nucleo fisso (F).Fig. 3.The device comprises a programmer (P) including a main cam (CP) whose jerky rotation is controlled by a step pawl (N), and a stop member (L) adapted to assume an unlocked position and a position of block in which it allows and respectively prevents the engagement of the pawl (N) with the main cam (CP). An electromagnetic device (E) is associated with the stop member (L) with a coil (B), a core capable of holding the stop member in one of said positions when the coil (B) is energized. The programmer (P) comprises means (21) adapted to place the mobile core (M) at the fixed core in a condition of excitation of the coil (B), for which the latter is sized so as to develop only the force sufficient to retain the mobile core (M) at the fixed core (F). 3.
