Problems solved by technology

[0009] However, as described above, the inlet 512 and the inlet space 518 are connected at a relatively small portion, such as the neck, and the inlet space 518 is connected to the side of the inlet 512, so that the inlet resistance of the sucked oil increases and a vortex is generated , and entry resistance and eddy current are the main factors that cause pulse 502 of rotor 504 to generate pulse noise during rotation

Abstract

A variable oil pump includes an inlet connected to supply oil into the housing of the variable oil pump an arc-shaped intake space formed in the housing to be connected to a pumping space between veins mounted on a rotor in the variable oil pump; and a buffer space having a large cross-sectional area than inlet and connected with inlet and intake space, such that it is possible to reduce pulse noise generated in the variable oil pump by reducing intake resistance and vortex which are generated in sucking oil at the intake side of the variable oil pump.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2010-0094806 filed on Sep. 29, 2010, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a variable oil pump, and more particularly, to a passage structure through which oil flows into the variable oil pump, which improves the flow rate of the discharge by adjusting the flow rate of the discharge according to the change of the number of revolutions of the engine. The fuel efficiency of the vehicle's engine and by utilizing the power provided from the engine to prevent unnecessary waste of energy when pumping oil. Background technique [0004] figure 1 with figure 2 The external shape and internal structure of a variable oil pump in the related art are shown, including: a driving gear 500 receiving power from an engine; a rotor 504 rotating by torque from the...
