Abstract

The moving driving element, which divides the servomechanism chamber into two, has several fluid receiving orifices fed by a fixed distributor connected to high and low pressure sources. The element has a number of holes which number at least three and an independent number of feeding orifices. There is at least one receiving hole between two emitting holes and their position and relative dimensions are such that all communication between high and low pressures is prevented regardless of relative positions. Between driving element and distributor.
