Abstract

Apparatus for continuous supply of high-pressure fluid comprises pressure- intensifying pumps with pressure- intensifying cylinders 1 and 2 within which operate pistons or rams 3 and 4 respectively. They feed, through non- return discharge ports 13 and 14, a common gathering chamber 17. If desired, two or more separate such chambers 17 can be used. The, or each, chamber 17 feeds through another non- return valve 18 the supply duct 19 provided with accumulator 20. Use of such a gathering chamber 17 reduces noise and gives smoother operation by absorbing sudden impact pressure changes at piston extreme positions. <IMAGE>
