Abstract (en)
[origin: EP0808665A2] The piston valve has a cylinder (5) containing a linearly displaced piston (1), with electrical isolation of the fluid inlet (12) from the fluid outlet (9), so that the fluid (8) can be held at earth potential at the inlet while the fluid (8.1) at the outlet is at a HV potential. The cylinder has an extension (11) associated with a control electrode (2), held at the same potential as the fluid at the valve outlet. Both the cylinder and the extension can be made of glass or ceramics.
