Open the CIPO recordAbstract From the Canadian patent
A hydraulic vibration brake for use in nuclear power plants is shown. The brake has a casing that a piston divides into two chambers. A storage tank in hydraulic fluid communication through appropriate conduits and valves maintains proper pressure in the system. The piston rod penetrates the casing wall and at this penetration has a seal which arrests fluid leakage. In this manner, no hydraulic fluid is lost at the seals and sufficient fluid always is available to enable the brake to carry out its function thereby, eliminating the need for a number of burdensome inspections.
