发明名称 Dual pressure cylinder
摘要 A self contained dual pressure cylinder for use in tensioner assemblies for oil and natural gas floating vessels. The self contained dual pressure cylinder can have a high pressure outer barrel surrounding a high pressure inner barrel, forming a high pressure gas channel, a low pressure outer barrel surrounding a low pressure inner barrel, forming a low pressure fluid channel. A high pressure gas port connected to a high pressure gas reservoir, a low pressure fluid port connected to a low pressure gas reservoir, a low pressure fluid compression area connected to the low pressure fluid port, a hollow rod slidingly engaged each inner barrel, a dual pressure capture plate with moveable rod seals and moveable rod wear, a piston a low pressure elastomeric seal, a low pressure/high pressure separator, and a high pressure elastomeric seal.
