Detailed description of the invention

Embodiment, with reference to accompanying drawing 1 ~ 5, is connected with fastening bolt 17 lockings between the pump housing 1 of constant acceleration curve low noise vane pump in large discharge capacity and protecgulum 14, and side plate 3 and stator 2 are housed in the pump housing 1 inner chamber. Rolling bearing 11, spacer 12 and valve plate 13 are housed respectively in the inner chamber of protecgulum 14, spacing with hole jump ring 16 between spacer 12 and rolling bearing 11, spacing with alignment pin 8 between side plate 3, stator 2 and valve plate 13. The both sides of side plate oil-in 3-2 on the working face of side plate 3 and side plate oil drain out 3-3 are respectively equipped with damping trough 3-1, and the cross section of damping trough 3-1 is isosceles triangle, and damping trough 3-1 is communicated with side plate oil-in 3-2 and side plate oil drain out 3-3 respectively. Stator 2 is provided with stator oil-in 2-1, between stator oil-in 2-1 and side plate oil-in 3-2, be communicated with, circular curve two 2-5, two sections of easement curve one 2-2 and two sections of easement curve two 2-3 that diagonal angle is symmetry equivalent that diagonal angle is symmetry equivalent that on the border line of stator 2 inner chambers, are respectively equipped with the arc diagonal angle symmetries such as two sections of circular curve one 2-4 that wait arc diagonal angle symmetries and two sections, easement curve one 2-2 and easement curve two 2-3 are constant acceleration curve. Intersection point between circular curve two 2-5 and easement curve one 2-2 is flex point one 2-6, and the intersection point between circular curve one 2-4 and easement curve two 2-3 is flex point two 2-7, between two flex point one 2-6 and two flex point two 2-7, is diagonal angle symmetry.
