| 摘要 |
<p>The invention relates to a multi-way valve device, particularly for household appliances, comprising a hollow body (11) and an axially movable piston (12) mounted inside this hollow body. The body (11) is provided with at least one inlet orifice (15) for a liquid solvent and at least two outlet orifices (16, 17) for this solvent. The movable piston (12) is coupled with an axially movable measuring stem (31) of a linear measuring element (30) of a solid substance, this measuring stem (31) being actuated by a mechanical actuator (32) and associated with a return spring (35). This movable piston (12) is arranged so as to move in one direction, freely, or against the pressure of the return spring (35), under the effect of the pressure of the liquid solvent applied at the inlet orifice (15) to this movable piston (12), and in the opposite direction, under the effect of the pressure applied to the measuring stem (31) by the return spring (35).</p> |
