Abstract: PURPOSE: A variable oil pump is provided to prevent overloads on an engine by decreasing oil pressure, and expanding an oil discharge space into the space of first and second pressure chamber. CONSTITUTION: A variable oil pump comprises a housing(5), a pressure chamber(20), and a variable spring(10). The pressure chamber discharges oil flowing into an outer ring, which encloses a rotary vane(3) with a rotary shaft. The pressure chamber comprises a first chamber(21), a second chamber(22), and a pressure interlock body(30). The first chamber is formed in between the outer ring. The second chamber is formed near a connection rigng, and connected to an oil supply path(23), which is formed along the housing. The pressure interlock body connects or secludes the oil supply path according to the location of the connection ring. The variable spring is extended toward the connection ring according to engine RPM.

Abstract: PURPOSE: An oil pump driving system for a vehicle engine is provided to vary the driving revolutions per minute according to the revolutions per minute of the engine, thereby improving the power performance and fuel efficiency performance of a vehicle. CONSTITUTION: An oil pump driving system for a vehicle engine includes a pump housing(10), a slider(11), a spring support(12), a relief spring(14), a spring mounting part(13), and a first and a second hydraulic chamber(211,222). The relief spring is mounted on the pump housing, and provides a restoring force to the spring support. The spring mounting part for mounting the relief spring is installed in the pump housing in response to the spring support. The first and the second hydraulic chamber are formed on the outer circumferential surface of the pump housing, and are mutually blocked and partitioned so that the slider is rotated on a pivot(P) by a hydraulic force. A connection between the first and the second hydraulic chamber is selectively opened or closed.
