The end of lever and make roller depart from contact with lever.
It is used for the improvement further of the pressurizer of oil cylinder as this utility model, the periphery of plunger rod is provided with and only allows punching
The guide part of head rod vertical direction degree of freedom.So guarantee the vertically upper and lower motion of the correct direction of motion of plunger rod.Equally
Similar guide part can be also provided with master cylinder.
It is used for the improvement further of the pressurizer of oil cylinder as this utility model, the lower section of lever is provided with groove, groove
The size of width is mated with the size of roller axial direction, and roller is rollably arranged in groove.Such setting is further ensured that
The transmittance process of power is stable, direction zero deflection.
This utility model can be applied in numerous hydraulic systems needing and being pressurized so that hydraulic system steady pressure can
Further up, reach necessary requirement；It is specifically applied on scrap metal machine and is just to increase system pressure, cake block density rises, and reaches
Customer demand.Even pressurizing cylinder can be saved, in the case of maintaining system pressure, mechanically also can make drift
Pressure increase, suppress satisfactory cake block.
