🔍 Key Concepts

• This is a pressure‑compensated variable displacement pump – as system (high‑side) pressure rises, the control works to reduce the pump stroke/tilting box angle to limit pressure. • Trace how oil from the high‑pressure transmission sensing port moves spool H–G and then how that motion is transmitted mechanically through D and E to the tilting box control arm. • Compare which choices describe the tilting box angle being reduced versus increased, and which ones actually match the direction of motion shown in the illustration.

💭 Think About

• Start at the high‑pressure transmission sensing port: if pressure increases, which way will the small piston by H move, given the opposing spring on the right? • When H–G shifts, does it allow replenishing‑pump oil to keep flowing, or does it throttle/block that flow and vent to drain? How would that affect the force on the large control piston tied to link D? • If link D is pulled in the direction shown (clockwise or counter‑clockwise), does that move the tilting box toward maximum angle or back toward neutral (reduced displacement)?

✅ Before You Answer

• Verify which labeled part actually senses high‑side pressure (J/H area) and which part is the set‑point spring (F). • Confirm which parts are in hydraulic control (G, H, J) and which are purely mechanical linkages (D, E) to the tilting box. • Check that the statement you pick shows the control acting to reduce pump displacement/tilting box angle as pressure rises, not increase it or simply "re‑establish" the original angle.

Question 1 of 20

A variable displacement pump is fitted with the illustrated device, the discharge flow rate will be reduced as described by which of the following statements? Illustration GS-0040

As high side pressure increases part "A", "B", and "C" will work together to re-establish the original tilting box angle.

When part "D" rotates counter-clockwise, part "E" will rotate clockwise allowing part "G" to slide towards the set point spring "F".

The increase in high side pressure will gradually increase the tilting box angle of the variable displacement pump.

Part "H" will move to block the replenishing pump oil flow across part "G" as flow across hydraulic motor decreases.
