Abstract
The valve comprises a slider-valving member having two lateral valving elements ( A, B) positioned on one and the other side of the transverse central plane, they being subjected to the direct action of thrust means ( ) and movable axially between a first operative position defining said normal configuration of the slider-valving member ( A, B), and a second operative position in which a further different communication condition between the channels is determined; spring means ( ) are also provided, arranged to normally maintain the two lateral valving elements ( A, B) in said first operative position. The said valve thrust means ( ) are operated either individually or simultaneously, their action being such that when they act individually on the slider-valving member ( A, B), this maintains its normal configuration, whereas when they act simultaneously on the lateral valving elements ( A, B), these are moved into said second operative position against the action of the spring means ( ).
