摘要： A valve device for use in filling cartons includes a tubular housing 38 containing a valve member 43 comprising a closure part 44 co-operating with a valve seat 50 at the lower extremity of the housing 38, and a driving part 46 movably received with clearance in the housing 38. During the latter part of the opening movement of the valve member 43 against a spring 48, the clearance increases smoothly and considerably, and the driving part 46 reaches a force equilibrium position at which the clearance is considerable. Two grooves 64 and 65 formed in the housing 38 and the valve member 43 immediately below the annulus of sealing bound an annular enclosed space for receiving liquid squeezed out downwardly at the valve seat 50 as the closure part 44 closes. Fins 47 extending upwards from the part 44 support a co-axial tubular part 70 which is a sliding fit in the housing 38 and which terminates short of the part 44 to leave liquid outlets 72.

摘要： A multifunctional safety valve device (1) with an incorporated proportional pressure regulator, said device comprising a body (2) in which a conduit (3) for a fluid or gas is defined and connected to a gas feed line and to a line delivering the gas to the user, said conduit (3) comprising a first passage (6) to be intercepted by a first valving element (4A) of a first valve member (4) and a second passage (7) to be intercepted or selectively restricted by second valving element (5A) of a second valve member (5), positioned downstream of the first, to act as a gas pressure regulator and modulator, said valving elements (4A, 5A) being operated by corresponding electromagnetic actuators (15, 16) and urged into closure, the device comprising means for compensating the action of the electromagnetic actuator (16) of the second valve member on the basis of the thrust exerted by the spring (31) on the corresponding valving element (5A), said means allowing any variation in the spring thrust force to be compensated such as to maintain the gas flow regulating action by the regulator constant with time, the compensator means comprising a profiled end (89) of a movable core (83) present in an actuator chamber (100) containing said core, in a position corresponding with a cylindrical element (61) inserted into and fixed in said chamber (100), said end (89) being close to or at most disposed in correspondence with the end (61 K) of said element (61).

摘要： A fluid control valve used as an expansion valve 1 has valve portions 22 and 23 integrally formed with a valve element 20 which is simultaneously movable relative to valve seats12, 31. Flow passage cross-sections formed by gaps between the valve portion 22 and the valve seat 12, and between the valve portion 23 and the valve seat 31 have approximately the same sizes when the expansion valve is open. The influence of variations of the effective pressure-receiving areas of the valve elements when the expansion valve is open, on the pressure balance, is almost cancelled to prevent degradation of the accuracy of flow rate control dependent on the lift amount of the valve elements.
