Hydraulic machine provided includes rotary valve plate having counter-weighting plate divided into inner plate and outer plate spaced by radial gap

摘要

The hydraulic machine has a valve between the fluid connections and the working unit provided with a rotary valve plate (11), acted on by a counter-weighting plate on one side, divided in the radial direction into an inner plate (15) and an outer plate (16). The inner and outer plates are relatively spaced by a radial gap (17) sufficient to prevent contact between them.
