Abstract
A valve, including: a casing having a chamber extending in a longitudinal direction, having the casing a hole at one end of the chamber; a drive inside the chamber in movement longitudinally between the open and close positions, being properly sealed in the closing position of the hole; a spring, for driving the drive to the open position against the longitudinal direction; an externally adjustable thread element in extension and passing through the casing and into the chamber; a latch, for limiting the drive in longitudinal movement based on the hole, in connection the drive with the screw, to drive the screw element in the first angle of the latch in longitudinal movement per the screw and the lateral movement of the chamber; a second angle surface on the drive, driven by the spring mainly toward the first angle surface, where the first and the second angle surface being for adaptation and sliding one against the other on the same plane; and the screw element being run externally, and the latch in longitudinal movement along the screw and in lateral sliding along the chamber, and the first angle surface being adjusted and set to a predetermined position, where the first angle surface determines the maximum trip of the drive in longitudinal direction, so that the first angle surface helps in determining the critical flow rate of the valve.
