FIELD: machine building.SUBSTANCE: hydraulic and pneumatic diode (1) has channel (2) of round section, in which there is at least one group of elements consisting of rings (3), the distance between tops of figures in the rings section is equal to Δ. At the inlet and the outlet of the hydropneumatic diode there are stabilizing grids (4). Coaxial to the channel there is rod (5) with the possibility of its movement and fixation along the diode channel axis through the thread in the stabilizing grids. Working elements (6) are rigidly fixed on the rod at distance Δ equal to the distance between the tops of the figures in the rings section. During movement of the working medium through the channel in the forward direction the flow enveloping the working elements and the ring does not meet significant resistance. During movement of the medium in the reverse direction the flow meets resistance in the form of the working elements or the rings, and the diode resistance becomes higher.EFFECT: provided is the possibility of controlling the diode capability by changing relative positions of the diode working elements and the rings.4 cl, 7 dwg |
