摘要： Clothes washing machine provided with a drawer having a plurality of compartments for detergents and additives. The selective water supply to the compartments of the drawer ist performed by means of a horizontal plate provided with inner pipes (8, 8′8˝) and holes (10,12) on its lower surface. The position and diameter of the holes are so arranged as to ensure a correct water supply regardless of the pressure of the water mains.

摘要： A speed variator for a laundry washing machine comprising a drum (6) mounted for rotation in a laundering tub (5) and adapted to be rotated at different speeds by a motor (7) via a transmission belt (8) interconnecting a driving pulley (9) of motor (7) and a driven pulley (10) associated with the drum. The driving pulley (9) of the speed variator is of the variable-diameter type and cooperates with a number of radially expandable flyweights (14).
The driving pulley (9) and the motor (7) are carried by a rotatable carrier arm (19) having one of its ends hingedly connected to a lower portion of the tub (5), while its other end is connected to a piston (29) mounted for reciprocating displacement to different operating positions in a cylinder (39) connected through a solenoid valve (31) to the water supply circuit of the machine.
The carrier arm (19) is biased by a torsion spring (25) to a position in which the driving pulley (9) is effective to keep the belt (8) under tension against the action caused by the radial expansion of the flyweights (14).
The piston (29) acts on the carrier arm (19) in a manner to interdict or to permit the radial expansion of the flyweights (14) to varying degrees depending on the respective position of the piston.
As a result, the effective diameter of the driving pulley (9) is varied by different degrees, permitting the drum (6) to be rotated at variable speeds.摘要翻译： 一种用于洗衣机的变速器，包括：滚筒（6），其安装成用于在洗衣桶（5）中旋转并适于通过传动带（8）以不同速度旋转，所述传动带（8）将驱动滑轮 9）和与滚筒相关联的从动皮带轮（10）。 变速器的驱动滑轮（9）具有可变直径型，并与许多径向可扩展的飞轮（14）配合。驱动滑轮（9）和马达（7）由可旋转的载臂（ 19），其一端铰接地连接到所述桶（5）的下部，而其另一端连接到活塞（29），该活塞安装成用于往复移动的活塞（29），以在通过螺线管连接的气缸（39）中的不同操作位置 阀（31）到机器的供水回路。 承载臂（19）被扭转弹簧（25）偏置到驱动滑轮（9）有效的位置，以使带（8）处于紧张状态，以防止由飞轮（14）的径向膨胀引起的动作 ）。 活塞（29）以取决于活塞的相应位置的方式阻挡或允许飞锤（14）的径向膨胀变化的程度作用在承载臂（19）上。 结果，驱动带轮（9）的有效直径以不同程度变化，允许鼓（6）以可变速度旋转。

摘要： Water distribution device for household washing machines including a cold-water inlet system (19) and a separate hot-water inlet system (18), each one of said systems being essentially formed by a conduit (18, 19) connected with the water supply on one side and a common water distributing element (1) on the opposite side.
Said element (1) is designed to simultaneously receive through a number of channels (9, 10) both cold and hot water, and to admit said water flows into separate and preselected inlets (5, 6, 7, 8) of a water dispenser capable of supplying, according to the wash cycle, said flows to a plurality of compartments containing the various chemical products required to perform a complete laundering process.摘要翻译： 用于家用洗衣机的配水装置包括冷水入口系统（19）和单独的热水入口系统（18），所述系统中的每一个基本上由与供水系统连接的导管（18,19）形成， 在一侧上和在相对侧上的共同的水分配元件（1）上。 所述元件（1）被设计成同时通过多个通道（9,10）接收冷水和热水，并且允许所述水流进入饮水机的单独的和预选的入口（5,6,7,8） 根据洗涤循环能够将所述流供应到包含进行完全洗涤过程所需的各种化学产品的多个隔室。
