<p>The high pressure valve (1) has an inlet (2) joined to a suction duct (4) leading to the inner space of the cylinder (5) of the pump, which is also connected to a high pressure duct (6) via the outlet (3). A ball retaining valve (7, 8) is positioned at the inlet (2), the outlet (3) respectively, each of them provided with an outer thread to be joined to the inner thread located at the insertion area. The diameter of the conical tips of the valves (7, 8) is slightly bigger than the diameter of the insertion areas, resulting in a tight fit.</p> |
