<p>The piezoelectric bending element (7) has a free side (9), which closes or releases the sealing seat (3,4), corresponding to an applied control pressure. The piezo bending element (7), at least in the region situated in the inner chamber (2) of the housing (1), is provided with a covering (10) of at least partly elastic insulating material, which on the held side (11), simultaneously also at the inner chamber (2) of the housing seals in an outward direction.</p> |
