Title:
HYDRAULIC DAMPER
Document Type and Number:
WIPO Patent Application WO/2015/158104
Kind Code:
A1
Abstract:
Disclosed is a hydraulic damper comprising a rotor (1), a stator (2) and a drive shaft (3) for driving the rotor (1), the rotor (1) and the stator (2) being mutually forming a working chamber (4) in which liquid medium is accommodated, wherein the stator (2) is provided in turn with an outlet (21), a nozzle (22), an exhaust channel (23), an ejector channel (24) and an inlet (25); the outlet (21), the exhaust channel (23) and the inlet (25) are communicated with the working chamber (4) respectively; the ejector channel (24) is in communication with the outlet (21),the exhaust channel (23) and the inlet (25) respectively; the nozzle (22) is arranged at the junction where the outlet (21) is connected with the exhaust channel (23) and the ejector channel (24); the nozzle (22) is extended along the lead-out direction of the outlet (21) to the junction where the exhaust channel (23) is connected with the ejector channel (24), and the channel width of the nozzle (22) at the extension is smaller than that of the outlet (21) and that of the ejector channel (24) respectively. With the Bernoulli's principle, hydraulic damper proposed in the present application can effectively avoid the loss of the liquid medium in the working chamber (4).
