More Information
Summary:The invention relates to a damping device which may rotate a rotor under a high load state when the rotor just starts to rotate. In the damping device (7), a blade (34) is disposed on the rotor (11). A one-way valve (39) installed on the blade (34) is an elastomer such as resin and is moved with the rotor (11). Further, the one-way valve (39) is elastically deformed by the fluid pressure of viscid fluid when the rotor (11) is rotated clockwise (CW). Therefore, a front-end portion in an axis direction is displaced so as to open a fluid flow path (38d). Moreover, the one-way valve (39) restores an original shape in virtue of the elastic restoring force of the one-way valve (39) itself when the rotor (11) is stopped such that the fluid flow path (38d) is closed. As a result, when the rotor (11) is rotated counterclockwise (CCW), the load of the fluid is applied to the rotor (11) when the rotation starts such that the rotor (11) is rotated under a high load state.
