Title:
PRESSURE BOOSTING TYPE HIGH PRESSURE VESSEL
Document Type and Number:
Japanese Patent JPS60220203
Kind Code:
A
Abstract:
PURPOSE:To raise pressure boosting performance, durable service time length due to fatigue, and safety of a vessel by disposing a vent passage in a space communicating a large diameter hole and a stepped part of a stepped piston, and providing a pressure controlling mechanism in the vent passage. CONSTITUTION:The vent passage is disposed in the space 7 communicating the large diameter hole 1'a and the stepped piston 4, and pressure controlling mechanism 13 is provided in the vent passage. Whereby, as the pressure in the space 7 may be controlled by pressure controlling mechanism 13 provided outside of the vessel, and the displacement of the stepped piston 4 may be also controlled, the pressure boosting performance of a pressure medium in the cylindrical vessel may be raised. Since the pressure controlling mechanism is provided outside of the vessel, the durable service time length due to fatigue and safety of the cylindrical vessel may be raised.
