The reservoir comprises an administration port connected to the channel, a cup contained in the channel and located movable between the administration port and the delivery passage, a cup spring biasing the cup against the administration port and one of the passages, and a yoke 68 movably positioned between at least two positions. The yoke is connected to the cup. When the yoke is positioned at one of the two positions at least, it prevents the cup from moving. When the yoke is positioned at the other one of the two positions at least, it has a rachet allowing the cup to move. <P>COPYRIGHT: (C)2008,JPO&INPIT |
