Abstract

Movable- jaw crusher (1) for rubble and similar, having an outer supporting structure (2) in which a crushing chamber (3) is formed; two crushing jaws (4, 5) positioned facing each other inside the crushing chamber (3) to define two sloping lateral walls of a downward- tapering hopper; and a jaw actuating device (6) for moving the two crushing jaws (4, 5) cyclically towards each other to crush the material fed between the crushing jaws (4, 5); the jaw actuating device (6) having at least one hydraulic thrust -bearing cylinder (15), in turn having an outer tubular casing (17), a movable piston rod (18) inserted telescopically inside the outer tubular casing (17), and a variable-volume inner chamber (20) which is reduced in volume when the movable piston rod (18) withdraws inside the outer tubular casing (17); the jaw actuating device (6) also having a pressure sensor (21) for detecting the instantaneous pressure of the fluid inside the inner chamber (20) of the hydraulic thrust -bearing cylinder (15), an electrically controlled on-of f valve (22) for selectively draining pressurized fluid from the inner chamber (20), and an electronic central control unit (23) for controlling the on-of f valve (22) to selectively drain pressurized fluid from the inner chamber (20) when the pressure of the fluid in the same chamber exceeds a maximum trigger threshold memorized in said control unit.
