2results about How to "Avoid serious impact" patented technology

Provided are a linear damper capable of reducing great collision sound or impact even when a great load rapidly acts and a steering device including the linear damper. A steering device 100 includes a linear damper 120 between a rack bar 103 and a rack end 106. In the linear damper 120, a relative displacement body 140 is provided to be reciprocatably displaceable in an inner chamber forming body 121 formed in a cylindrical shape. In the inner chamber forming body 121, a first inner chamber 125a and a second inner chamber 125b are formed on both sides of a valve support portion 123 supporting first flow control valves 127 and a second flow control valve 128. An end portion of the inner chamber forming body 121 facing a rack housing 104 is provided with a bumper portion 131. The bumper portion 131 is produced in such a manner that an elastically-deformable elastic body is formed into a circular ring shape.

This invention discloses an underwater dynamic seal monitoring and flushing device, comprising a sealing housing and a first suction pump, a first check valve, a collection tank, a liquid level sensor, a second suction pump, and a second check valve arranged sequentially within the sealing housing. It also includes a discharge pipeline connecting the sealing cavity and the first suction pump, with a flushing fluid / compressed air inlet on the discharge pipeline, connected to an air control unit and a flushing unit storing the flushing fluid via a first solenoid valve and a second solenoid valve, respectively. The suction pump, collection tank, liquid level sensor, and discharge pipeline of this invention enable real-time monitoring of leakage in the dynamic seal device, effectively assessing sealing performance and seal life, and avoiding serious consequences from seal failure. Simultaneously, the flushing device of this invention provides good cooling and lubrication conditions for the dynamic seal device, contributing to an extended seal life.
