<p>This invention solves the construction of the control element having an asymmetric geometry of control edges in order to control pressure and flow of liquid. This control element consists of the shifter (6) located in the cylindrical guide (7) created in the body (18) of the control element and equipped with the controlling recess (8), where the output hole (12) is connected. The input hole (10) connected to the pressure source (11) is outgoing to the cylindrical guide (7) and it is located after the right control edge closed to the shifter (6). On the shifter (6), there is created the control collar (3) located in the place of the control recess (8). This solution is based on that principle, that the first edge (1) closed to the control collar is created by at least one continual hole (2) connected to the inlet hole (10) and the second control edge (4) is created by the front head (5) of the control collar.</p> |
