Silage stripping reservoir for e.g. distributing maize to animal, has valve tilted from its closed position when supply pressure of motor attains certain threshold, and interposed on hydraulic connection circuit

摘要

The reservoir has a valve (410) e.g. monostable valve, interposed on a hydraulic connection circuit (422) connecting a chamber of a double-effect hydraulic cylinder (320a) to a control distributor (DC) e.g. open-center control distributor. A nozzle (450) is interposed on another hydraulic connection circuit (460). A hydraulic motor (350) is connected between the former circuit and a third hydraulic connection circuit (424). The valve is controlled by a fourth hydraulic connection circuit (442), and is tilted to its closed position when supply pressure of the motor attains certain threshold.
