Abstract

1281627 Hydraulic intensifiers AISIN SEIKI K K 14 Oct 1970 [18 Oct 1969 20 Jan 1970] 48914/70 Heading F1P An hydraulic intensifier comprises a housing 1 containing small and large diameter piston portions 5, 6, the piston portion 6 having a bore 7 in which a control valve means 8 can reciprocate to control reciprocation of pistons 5, 6 which serve to change fluid into accumulator 43. Piston 5 defines a chamber 4 in bore 2 of the housing, the chamber 4 being connected to a fluid-pressure source P and an accumulator 43 via ports 51, 41. Between bore 7 and valve means 8 are defined annular chambers 28, 30, 34. Chamber 28 is connected to inlet port 24 in bore 3 via passages 27, 26, 25. Chamber 30 is connected to a chamber 19 in bore 3 via passage 31, and chamber 34 is connected to a reservoir R via passage 35, exhaust chamber 118 and port 40. Three radial ports 20, 22, 23 can be selectively connected via annular passage 45, radial passage 46 and axial passage 53 to a chamber 21 defined between adjacent ends of valve means 8 and piston 6. In operation, pump P supplies fluid to ports 24, 51. The pressure to port 24 is transmitted to chamber 28 via passages 25, 26, 27 and to chamber 21 via port 22 and passages 45, 46, 53. Fluid pressure to port 51 is transmitted to accumulator 43 via chamber 4. At a predetermined pressure in chamber 21, valve means 8 moves to the left opening communication between chambers 28 and 30, such that fluid can flow to chamber 19 via passage 31 to move piston 6 to the right. When the Fig. 2 (not shown) position is reached, chamber 21 communicates via port 22 with exhaust chamber 118 and valve means 8 is urged to the right by spring 10. This opens communication between chamber 30 and 34 and the fluid in chamber 19 is thus exhausted so that pressure in chamber 4 returns pistons 5 and 6 to their original position, Fig. 1. The rightwards movement of the pistons serves to charge the fluid-pressure in the accumulator to a higher pressure than that of the source. The process is continued until the desired accumulator pressure is achieved.
