A combustion system including a plurality of axially staged tubular premixers to control emissions and minimize combustion noise. The combustion system includes a radial inflow premixer that delivers the combustion mixture across a contoured dome into the combustion chamber. The axially staged premixers having a twist mixing apparatus to rotate the fluid flow and cause improved mixing without causing flow recirculation that could lead to pre-ignition or flashback.

A hydraulic drive system according to claim 1, wherein said pressure control means is a check valve (39) disposed in said pilot passage (15b) and cutting off a flow of the hydraulic fluid from said hose connection chamber (9) to said back pressure chamber (10). 3. A hydraulic drive system according to claim 1, wherein said pressure control means comprises a check valve (40) provided inside said poppet valve member (5) and allowing a flow of the hydraulic fluid from said backpressure chamber (10) to said cylinder connection chamber (8), and means (41) disposed said pilot passage (15b) and generating a differential pressure between said hose connection chamber (9) and said back pressure chamber (10).
