Abstract: A sanitary shredder includes at least a channel feeding water into a caisson (1), an electric motor whereof the axis has at its end a rotor pump (5) with blades (6), and shredding elements opposite the shredding chamber (3) provided with an inlet. The front surface (5a) of the rotor (5) is substantially planar and comprises a plurality of passages for water arranged substantially radially and emerging on the circumference of the rotor (5), each passage of the rotor (5) is extended by a channel delimited by the helical blades (6), the rotor (5) is housed in the pump body (8), its front surface (5a) being substantially in the plane of the pump body opening, shredding members (9) being arranged in axial projection relative to said front surface (5a).

Abstract: A flushing mechanism for toilet tank comprises an overflow tube (1) provided with a sealing valve (3, 4) co-operating with a discharge orifice (5?) including a first floater (30) mounted on a height-adjusting screw (31) and a second floater (40) mounted pivoting about a fixed pin (41). The adjusting screw (31) is articulated (33) on a lever (34) articulated about a fixed pin (35), the lever (34) is provided with a snug (36) co-operating with a first locking cam (37) and the second floater (40) is provided with a snug (42) co-operating with a second locking cam (43). The invention is applicable to double-volume flushing systems.
