from zero to full flow (acceleration) or full flow to zero (deceleration) is a net function of spool porting,

orifices, and charge pressure.

H1 pumps are limited in mechanical orifice combinations. Mechanical servo orifices are to be used only

for fail-safe return to neutral in a case of an electrical failure.

A swash-plate response times table is available for each frame size. Testing should be conducted to verify

the proper orifice selection for the desired response. Typical response times at the following conditions:

∆p = 250 bar [3626 psi]

Charge pressure = 20 bar [290 psi]

Viscosity and temperature = 30 mm²/s [141 SUS] and 50 °C [122 °F]
