Control device for variable flow vol hydrostatic machine - performs rapid control pressure correction via variable flow cross=section discharge points along control line

摘要

The control device has a control pressure source (2), coupled via a control line (3) with a control pressure sensor (4) coupled to the setting adjustment for the hydrostatic machine (5). The control pressure line (3) has controlled discharge points (12,..16) with variable flow cross-section, for rapid adjustment of hydro-static machine flow vol, in response to a control pressure correction signal. Each discharge print (12...16) is connected to a branch line (9) of the control pressure line (3) downstream of a throttle point, with a pressure balance (25) between the control pressure line (3) and the branch line. ADVANTAGE - Rapid adjustment of hydrostatic machine flow vol.
