PRESSURE REGULATION CONNECTION FOR VARIABLE-VOLTAGE HYDROGENERATOR

摘要

The solution deals with the control hydraulic generator (1), which is equipped with the hydraulically controlled position servomechanism (2) and whose first and second main line (17, 18) is connected to the hydraulic motor (26). The shaft of the control hydraulic generator (1) is mechanically connected with the additional hydraulic generator (10), whose output line (9) is connected with the position servomechanism (2). The left and right control chamber (35) of the position servomechanism (2) is connected to the three-position distributor (7), whose input line (8) is connected with the output line (9) of the additional hydraulic generator (10). The waste line (11) of the three-position distributor (7) is connected via the control screen (12) to the waste line (11) of the drive, while the controlled safety valve (15) is connected with the three-position distributor (7) before the control screen (12). The controlled safety valve (15) is connected with the first main line (17) of the control hydraulic generator (1). Alternatively, the controlled safety valve (15) can be connected with the first main line (17) of the control hydraulic generator (1) via the return valve, which connects also with the second main line (18) of the control hydraulic generator (1). The control chamber (25) of the controlled safety valve (5) is connected via the controlled reduction valve (22) with the output line (9) of the additional hydraulic generator (10).<IMAGE>
