Abstract
Hydraulic machine control which consists of block segments on whose outside the necessary valves are arranged and where the individual block segments are assembled as central blocks and held together by tention anchors. Cone seat valves (10, 11, 12, 13, 14) are used to control the main flow and these are integrated directly into the individual block segments (1) such that the segments have bores (2, 3, 4) to accept these valve elements, which consist of valve guide casing (15), cut-off cone (16) and valve spring (17). Only the pre-central valves (20) and the setting mechanism (18, 19) are arranged outside on the block segments (1).
