Document Type and Number:
WIPO Patent Application WO/2015/160178
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a variable oil pump, which comprises one chamber·two-way valve·three-way solenoid valve and enables pressure changes in two stages under two preset setting pressures, so as to supply a proper flow rate required for an engine and the like, at a high speed according to a speed (rotational speed) of the oil pump, thereby preventing an overload applied thereto and stably supplying oil. Particularly, another purpose of the present invention is to provide a variable oil pump, which enables the pressure thereof to be adjusted in two stages through one chamber·two-way valve·three-way solenoid valve capable of being manufactured using a normal technique, thereby having a simple structure, enabling pressure to be correctly adjusted in two stages, and being easily manufactured and used at a low cost.
