Abstract
Abstract The distributor comprises a generally cylindrical case which is formed by a housing (1) and a cover (4) between which is rotatively mounted a distributor disk (18) provided with circumferentially spaced-apart orifices (48, 50). Inside the housing, a partition (24) defines a depression passageway (26) in communication with a suction duct (2). The passageway (26) includes a wide upper part (27) in the shape of a crescent which is extended at both ends by a narrow branch (28, 30). Formed in the upper part of the descending branch (30), relative to the direction of rotation of the disk (18), is a cavity (32, 33) for receiving a removable element (34) for isolating this branch from the source of depression. The inner wall of the passageway is provided with an air intake (39) whose opening is adjustable.
