PURPOSE:To quickly and smoothly drive a pintle and keep discharge flow rate at 0 when an input shaft is in an idle rotation speed area and effectively avoid the transient excessive system pressure generated in a load circuit in a variable displacement pump. CONSTITUTION:The initial eccentricity of a pintle 1b is prevented extending over a fixed range by a springs 9 and 10. In addition, sub-control pistons 7 and 8 activated by system pressure DELTAP are antagonized against main control pistons 4 and 5. |
