Abstract: 1,163,887. Pressure intensifiers. SPENCER FRANKLIN Ltd. April 29, 1968 [April 7, 1967], No. 16113/67. Heading F1P. In a pressure intensifier comprising a large piston 16 movable in a pneumatic cylinder 11 having an end housing 22 for the passage of an intensifier plunger 27 into an hydraulic cylinder 12, the plunger is guided by a bearing bush 33 removably mounted in the housing 22 so that it can be interchanged to suit a piston rod of different diameter when it is desired to alter the pressure intensification ratio. The bush 33 is disposed in an axial bore in the housing 22 and is held by the end of the hydraulic cylinder 12 screwed into the housing with the interposition of a gland 44. In the inoperative position of the intensifier the plunger 27 is urged by a spring 21 to uncover an annular groove 37 in the bush 33. The groove 37 communicates through passages 36, 42 with an oil reservoir 40. The oil intensified by the plunger 27 flows to devices to be operated through multiple ports 51 in a manifold 50 closing the cylinder 12.
