Abstract (en)
[origin: WO2014024117A2] The present invention concerns an assembly of manoeuvre (1) for a switch point comprising: - A circuit (4', 4", 14', 14", 14"') for the circulation of a fluid; - Means (2) for sending the fluid in pressure along said circuit (4', 4", 14', 14", 14"'); - An actuator (20) for commanding the manoeuvre and connected to the circuit in such a way as to translate in correspondence of the sending of the fluid in pressure; - And wherein a friction device (100) is further foreseen interposed in the circuit (4', 4", 14', 14", 14'"), said friction device (100) comprising at least a pressure valve (110, 115) arranged in such a way as to intercept the circulating fluid and measure the pressure value thereof in such a way that, in correspondence of the excess of a pre- established threshold pressure value, a block signal is generated.
