Reversing Movement diagram
Hydraulic Reversing Movement: Cylinder Speed and Force Calculator
Calculate ideal hydraulic cylinder extension and retraction speed and force. Compare bore and rod sizes and see how a directional valve reverses motion.
Flexible Ball Joint diagram
Flexible Pipe Ball Joint: Angle-Sum Comparison | FIRGELLI
Compare entered joint angles and equal-share demand in a simplified coplanar model. Learn why piping geometry and product ratings need separate checks.
Miscellaneous Hydraulic Motion diagram
Miscellaneous Hydraulic Motion Mechanism: How Rotary, Vane and Oscillating Actuators Work
Miscellaneous hydraulic motion covers oddball fluid-power circuits — rotary, oscillating, indexing — used in plant automation, marine gear, and heavy mobile equipment.
Mason Water-pressure Regulator diagram
Mason Water-pressure Regulator: Historical Diaphragm-and-Spring Operation
Explore the historical Mason regulator and compare ideal diaphragm pressure force with spring force. Calculate a static balance pressure, without valve sizing.
Hydraulic Transmission of Power diagram
Hydraulic Transmission: Ideal Piston Force, Travel and Work | FIRGELLI
Calculate ideal full-bore piston force, travel from displaced volume and constant-pressure work. Flow rate, cycle time and complete hydraulic-system efficiency are not calculated.
Hydraulic Intensifier diagram
Hydraulic Intensifier: Ideal Pressure and Displacement Ratios | FIRGELLI
Compare ideal linked-piston pressure multiplication and reciprocal displacement ratios. The calculator does not establish component ratings or continuous delivered flow.
Hydraulic Lift diagram
Hydraulic Lift Ram: Ideal Force and Swept-Volume Calculator | FIRGELLI
Convert ram bore and pressure into ideal force, force-equivalent mass, area and swept volume per millimetre. These values do not establish a lift’s load rating.
Hydraulic Device (form) diagram
Hydraulic Piston Force Calculator: Pressure and Bore | FIRGELLI
Calculate ideal gross cap-end piston force from pressure and bore. Compare newtons, kilonewtons and tonne-force; rod-side force, friction and component ratings are not included.

Explore the Emery pump with four guided rigid wings, a concentric pin groove and an eccentric hollow driver. Includes geometric pocket-volume calculations.
Vane Pump diagram
Vane Pump: Ideal Flow, Fluid Power and Torque Calculator
Explore sliding vanes in a cam ring. Calculate displacement flow, efficiency-adjusted flow, fluid power and theoretical torque; actual pump ratings and shaft losses require separate...
Gear Pump diagram
External Gear Pump: Flow, Fluid Power and Ideal Torque | FIRGELLI
Explore external gear-pump operation and estimate displacement flow, delivered flow, fluid power and ideal torque using a chosen volumetric efficiency.
Shuttle Valve diagram
Shuttle Valve Mechanism Explained: How It Works, OR Logic Diagram, Parts, Uses & Sizing Formula
See how a ball shuttle valve connects either inlet to a common outlet and blocks the other inlet. Compare incompressible-liquid Cv sizing assumptions.
