ABSTRACT:
A device (15) for slowing the movement of a drawer (2) urged by unidirectional thrust means (4), including a casing (17) fixable to a structure (S) and defining a chamber (18) filled with a viscous fluid, and a rotor (31). The rotor (31) includes a disc portion (32) and a shaft portion (33) protruding through the lid (21) of the casing (17) in such a way as it can be associated with the door (2). The base surface (23a) of the chamber (18) has a recess (51) operable to house a pivotable arm (52). The arm (52) has a pin portion (54) protruding into the chamber (18). The lower surface (62) of the disc portion (32) of the rotor (31) has a groove (70) for engaging the pin portion (54) of the arm (52). At one end (73), the groove (70) has a cam (76) dividing it into a return path (75) and a forward path (74) for the pin portion (54) so as to define a locking position for the rotor (31) in cooperation with the thrust means (4).
