摘要： A proportional valve (10) is described that is configured to be used inside a fluid-treatment machine, comprising a main body (12) provided with a first connection element (14) to the hydraulic circuit of the machine, configured for entering a fluid into the proportional valve (10), and with a second connection element (16) to the hydraulic circuit of the machine, configured for the ejection of the fluid from the proportional valve (10). Inside of the main body (12) there are at least an inlet duct (18) of the fluid, operatively connected to the first connection element (14), and at least one outlet duct (20) of the fluid, operatively connected both to the inlet duct (18), and to the second connection element (16). Inside of the main body (12), in an inner chamber (22) forming the intersection point between the inlet duct (18) and the outlet duct (20), there being further inserted an actuation piston (24), movable according to reciprocating motion, which is capable of selectively putting in communication the inlet duct (18) with the outlet duct (20). The actuation piston (24) is operatively connected to an actuation mechanism that comprises at least one elastic actuation member (30) made of a shape-memory alloy and an electric current generating device (32), operatively connected to the elastic actuation member (30) in order to modify, in a progressive and modulable manner, the value of the elastic force applied on the actuation piston (24) through a temperature variation caused by the passage of electric current inside the elastic actuation member (30).

摘要： A container assembly (10) for a pump is described, provided with at least one pumping group (12, 14, 16, 18) and with at least one system (20) for transmitting power to such pumping group (12, 14, 16, 18). The container assembly (10) comprises at least one elastic element (26) sealingly housed inside such container assembly (10) at a predefined internal wall (28) thereof. Inside the elastic element (26), at least one cavity (32) is obtained which defines a corresponding air chamber configured for damping the variations of volume and the expansion of the fluid contained inside the pump following a possible change of state of the fluid itself when subjected to temperatures lower than its freezing point.
