The classification of hydraulic elements
Control component - directional control valve: one-way valve, reversing valve, etc. Pressure control valve: relief valve, pressure reducing valve, sequence valve, pressure relay, etc. Flow control valve: throttle valve, governor valve, shunt valve, etc. Auxiliary components - accumulators, filters, coolers, heaters, tubing, pipe joints, fuel tanks, pressure gauges, flowmeters, sealing devices, etc.
Is the conventional categories: dynamic components (pump), executive components (cylinders, motor), control components (pressure control valve, flow control valve, direction control valves), auxiliary components (tank, pipe fittings, accumulators, filters, seals, etc.).
Power component - gear pump, vane pump, plunger pump, screw pump, etc. Execution component - hydraulic cylinder: piston hydraulic cylinder, plunger hydraulic cylinder, oscillating hydraulic cylinder, combined hydraulic cylinder, etc. Hydraulic motor: gear hydraulic motor, blade hydraulic motor, plunger hydraulic motor, etc.
