Abstract

Il cilindro motore (10) proposto dall'invenzione è dotato di un dispositivo di frenatura o/e di bloccaggio, i cui elementi di bloccaggio (61, 61A) vengono attivati tramite elementi di rotolamento (65, 65A), una bussola di comando (55, 55A) e un pistone di comando (50, 50A). Il dispositivo di frenatura o/e di bloccaggio è collegato al pistone (12) del cilindro motore e gli elementi di bloccaggio (62, 62A) poggiano sulla parete interna (63) della cassa (11). Il dispositivo di frenatura o/e di bloccaggio viene attivato mediante una molla di compressione (58, 58A), che agisce sul pistone di comando (50, 50A). Per staccare il dispositivo di frenatura o/e bloccaggio, sul pistone agisce la pressione esistente in una camera di pressione (53, 53A) situata sul pistone. L'azione esercitata dalla pressione presente nella camera di pressione è opposta a quella della molla di compressione. La camera di pressione (53, 53A) viene alimentata, tramite canali per fluido in pressione presenti nel pistone, dalla pressione di servizio del cilindro motore. Pertanto, con l'eccitazione del cilindro motore ovvero di una delle camere di pressione, il dispositivo di frenatura e/o bloccaggio viene sbloccato automaticamente. Se si scarica la camera (o le camere) di pressione, gli elementi di bloccaggio si appoggiano alla parete interna della cassa.(Figura 1).The motor cylinder (10) proposed by the invention is equipped with a braking or / and locking device, the locking elements of which (61, 61A) are activated by rolling elements (65, 65A), a control bush ( 55, 55A) and a control piston (50, 50A). The braking or / and locking device is connected to the piston (12) of the engine cylinder and the locking elements (62, 62A) rest on the internal wall (63) of the case (11). The braking or / and locking device is activated by means of a compression spring (58, 58A), which acts on the control piston (50, 50A). To release the braking or / and locking device, the pressure existing in a pressure chamber (53, 53A) located on the piston acts on the piston. The action exerted by the pressure present in the pressure chamber is opposite to that of the compression spring. The pressure chamber (53, 53A) is fed, through channels for pressurized fluid present in the piston, by the operating pressure of the engine cylinder. Therefore, with the excitation of the motor cylinder or one of the pressure chambers, the braking and / or locking device is automatically released. If the pressure chamber (s) are discharged, the locking elements rest on the internal wall of the case (Figure 1).
