Abstract (en)
[origin: EP1906019A2] The valve (10) has a valve body (18) engaging a position closing a passage and another position releasing a passage hole of a valve housing (12), and a coil spring (24) for applying a closing force on the valve body. The closing force pre-tensions the valve body into its position closing the passage hole. The valve body is designed and arranged in the valve housing such that a parallel effective contact surface of the valve body aligned in its position closing for free cross-section is null for the counter pressure in a counter pressure area (36). An independent claim is also included for an injection device for a phytosanitary technology, with a dosing pump.
