이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명하며, 이러한 실시예는 일례로서 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 여러 가지 상이한 형태로 구현될 수 있으므로, 여기에서 설명하는 실시예에 한정되지 않는다.DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Since the exemplary embodiments of the present invention may be embodied in various different forms, one of ordinary skill in the art to which the present invention pertains may be described herein. It is not limited to the Example to make.

도 1은 본 실시예에 따른 압력챔버유닛이 적용된 2단 가변오일펌프의 구성도를 나타낸다.1 shows a configuration diagram of a two-stage variable oil pump to which a pressure chamber unit according to the present embodiment is applied.

도시된 바와 같이, 2단 가변오일펌프는 전체적인 형상을 이루는 하우징(5)과, 동력을 전달하는 회전축(1)을 통해 구동되는 베인(3)과, 상기 베인(3)을 감싼 아우터링(4)과, 상기 아우터링(4)의 일측에서 연장된 연결링(4a)쪽으로 위치되어진 가변스프링(10)과, 오일을 토출하는 제1챔버(21)와 떨어져 연결링(4a)쪽으로 형성되어진 제2챔버(22)로 이루어진 압력챔버(20)와, 엔진의 회전수(RPM)상승에 따른 가변스프링(10)의 작용으로 밀려나는 연결링(4a)의 이동으로 상기 제1챔버(21)와 제2챔버(22)간을 서로 연결하거나 차단시키는 압력연동체(30)로 구성되어진다.As shown, the two-stage variable oil pump includes a housing 5 forming an overall shape, a vane 3 driven through a rotating shaft 1 for transmitting power, and an outer ring 4 wrapping the vane 3. ), A variable spring (10) positioned toward the connection ring (4a) extending from one side of the outer ring (4), and the first formed in the connection ring (4a) away from the first chamber 21 for discharging oil The first chamber 21 and the first chamber 21 are moved by the pressure chamber 20 formed of the two chambers 22 and the connecting ring 4a pushed by the action of the variable spring 10 according to the increase in the engine speed RPM. The second chamber 22 is composed of a pressure interlock 30 to connect or block each other.

상기 가변스프링(10)은 아우터링(4)을 수용하고 일측으로 상기 아우터링(4)에서 연장된 연결링(4a)을 위치시키는 수용챔버를 형성한 하우징(5)에 설치됨으로써, 상기 가변스프링(10)이 엔진의 회전수 상승에 연동되어 연결링(4a)부위를 밀어내 아우터링(4)의 궤적을 변화시키게 가해주게 된다.The variable spring 10 is installed in the housing 5 which accommodates the outer ring 4 and forms a receiving chamber for positioning the connection ring 4a extending from the outer ring 4 to one side. 10 is linked to the increase in the rotational speed of the engine to push the connection ring (4a) to change the trajectory of the outer ring (4).

상기 압력챔버(20)를 이루는 한쌍의 제1챔버(21)와 제2챔버(22)는 하우징(5)부위로 형성되어진 오일공급유로(23)로 연결되어진다.The pair of first chambers 21 and the second chambers 22 constituting the pressure chamber 20 are connected to an oil supply passage 23 formed at a portion of the housing 5.

상기 제1챔버(21)는 오일을 토출하는 아우터링(4)과 하우징(5)부위로 형성되고, 상기 제2챔버(22)는 아우터링(4)의 연결링(4a)과 하우징(5)부위로 형성되며, 상기 제1챔버(21)와 제2챔버(22)는 아우터링(4)을 이용해 서로 분리되어진 상태로 이루어진다.The first chamber 21 is formed of an outer ring 4 and a housing 5 for discharging oil, and the second chamber 22 is a connection ring 4a and a housing 5 of the outer ring 4. And the first chamber 21 and the second chamber 22 are separated from each other using the outer ring 4.

본 실시예에 따른 압력연동체(30)는 아우터링(4)에서 연장된 연결링(4a)에 일체로 형성되어 내부 구조를 형성하게 된다.The pressure interlock 30 according to the present embodiment is integrally formed with the connection ring 4a extending from the outer ring 4 to form an internal structure.

상기 압력연동체(30)는 오일압이 작용하는 빈공간인 챔버(31)와, 상기 챔버(31)를 구획하도록 수용되고 오일경로(32a)로 내부가 관통되어진 피스톤(32)과, 상기 피스톤(32)을 탄발지지하는 스프링(33)과, 상기 챔버(31)로 유입된 오일이 아우터링(4)의 연결링(4a)의 외부로 빠져나가도록 상기 챔버(31)에 연통된 연통홀(34)로 구성되어진다.The pressure interlock 30 includes a chamber 31 which is an empty space in which oil pressure acts, a piston 32 accommodated to partition the chamber 31 and penetrated therein by an oil path 32a, and the piston. The communication hole communicated with the chamber 31 so that the spring 33 which supports the 32 32 and the oil which flowed into the said chamber 31 escape to the exterior of the connection ring 4a of the outer ring 4; It consists of 34.

상기 피스톤(32)의 내부를 관통하는 오일경로(32a)는 제1챔버(21)쪽의 오일압을 제2챔버(22)쪽으로 공급하거나 차단하며, 피스톤(32)에 "┏" 단면으로 형성되어진다.The oil path 32a penetrating the inside of the piston 32 supplies or blocks the oil pressure of the first chamber 21 toward the second chamber 22, and is formed in the piston 32 in a "┏" cross section. It is done.

즉, 피스톤(32)의 상하면중 한쪽면에 수직하게 뚫리고 좌우측면중 한쪽 측면에 수평하게 뚫려 서로 연결되는 구조로 이루어진다.That is, it consists of a structure that is vertically drilled on one side of the upper and lower surfaces of the piston 32 and horizontally drilled on one side of the left and right sides.

도 2는 본 실시예에 따른 압력챔버와 압력연동체의 연결 상태를 나타낸다.2 shows a connection state of the pressure chamber and the pressure interlock according to the embodiment.

도시된 바와 같이, 압력챔버(20)의 제1챔버(21)에 인접된 제2챔버(22)는 아우터링(4)에서 연장된 연결링(4a)부위에 형성되고, 압력연동체(30)는 상기 연결링(4a)에 형성되어 연결링(4a)과 함께 움직여 제1챔버(21)와 제2챔버(22)를 연결하는 오일공급유로(23)를 개폐함으로써 제1챔버(21)쪽의 오일압이 제2챔버(22)쪽으로 공급되거나 차단시켜주게 된다.As shown, the second chamber 22 adjacent to the first chamber 21 of the pressure chamber 20 is formed on the connection ring 4a extending from the outer ring 4, and the pressure interlock 30 Is formed in the connecting ring 4a and moves together with the connecting ring 4a to open and close the oil supply passage 23 connecting the first chamber 21 and the second chamber 22 to the first chamber 21. The oil pressure of the side is supplied to or blocked by the second chamber 22.

즉, 상기 오일공급유로(23)가 피스톤(32)의 "┏" 단면 오일경로(32a)와 일치되면, 상기 오일경로(32a)를 통해 챔버(31)로 들어온 후 챔버(31)에 연통되도록 아우터링(4)의 연결링(4a)에 뚫린 연통홀(34)을 통해 제2챔버(22)쪽으로 빠져나가게 된다.That is, when the oil supply passage 23 coincides with the "┏" cross-sectional oil path 32a of the piston 32, the oil supply path 23 enters the chamber 31 through the oil path 32a and then communicates with the chamber 31. Through the communication hole 34 bored in the connecting ring (4a) of the outer ring (4) is exited toward the second chamber (22).

도 3은 본 발명에 따른 2단 가변오일펌프의 작동도를 나타낸다.Figure 3 shows the operation of the two stage variable oil pump according to the present invention.

도 3(가)는 가변스프링(10)이 아우터링(4)의 연결링(4a)을 밀어 낼 정도로 엔진 회전수가 증가되지 않아 아우터링(4)의 궤적을 변화시키지 않음으로써, 상기 연결링(4a)에 형성된 압력연동체(30)와 압력챔버(20)가 서로 차단된 상태를 나타낸다.3 (a) shows that the variable speed 10 does not change the trajectory of the outer ring 4 since the engine speed does not increase to the extent that the variable ring 10 pushes the connecting ring 4a of the outer ring 4. The pressure interlock 30 and the pressure chamber 20 formed in 4a are blocked from each other.

즉, 상기 압력연동체(30)의 피스톤(32)에 형성된 "┏" 단면 오일경로(32a)가 제1챔버(21)에서 이어진 오일공급유로(23)와 일치되지 않고 빗겨남으로써, 제1챔버(21)에 형성된 오일압이 제2챔버(22)로 전달되지 않게 된다.That is, the "┏" cross-sectional oil path 32a formed in the piston 32 of the pressure interlock 30 is deviated from the oil supply flow path 23 which is continued from the first chamber 21 and is combed. The oil pressure formed in the chamber 21 is not transmitted to the second chamber 22.

이로 인해 오일펌프는 제1챔버(21)를 통해서 유량을 토출시켜주게 된다.As a result, the oil pump discharges the flow rate through the first chamber 21.

도 3(나)는 엔진 회전수 상승에 따른 가변스프링(10)의 작용으로 아우터링(4)의 연결링(4a)이 밀려남으로써, 아우터링(4)의 궤적이 변화되어진 상태이다.3 (b) shows a state in which the trajectory of the outer ring 4 is changed by pushing the connection ring 4a of the outer ring 4 by the action of the variable spring 10 according to the increase of the engine speed.

이러한 연결링(4a)의 위치 이동은 압력연동체(30)의 위치도 이동시켜줌으로써, 상기 압력연동체(30)의 피스톤(32)에 형성된 "┏" 단면 오일경로(32a)가 체1챔버(21)에서 이어진 오일공급유로(23)와 서로 일치되어진다.The positional movement of the coupling ring 4a also moves the position of the pressure interlock 30 so that the "┏" cross-sectional oil path 32a formed on the piston 32 of the pressure interlock 30 is the first chamber. It coincides with each other with the oil supply passage 23 continued from (21).

상기와 같은 엔진 회전수 상승은 오일펌프의 오일압도 함께 상승시켜 제1챔버(21)쪽 오일압이 오일공급유로(23)로 빠져나가고, 상기 오일공급유로(23)로 빠져나간 오일압이 피스톤(32)에 형성된 "┏" 단면 오일경로(32a)를 통해 챔버(31)로 전달되어진다.The increase in the engine speed also increases the oil pressure of the oil pump so that the oil pressure of the first chamber 21 exits the oil supply passage 23, and the oil pressure exited into the oil supply passage 23 is a piston. It is transmitted to the chamber 31 via the "X" cross-sectional oil path 32a formed in the (32).

상기 챔버(31)로 전달되어진 오일압은 연통홀(34)을 통해 제2챔버(22)쪽으로 빠져나감으로써, 제1챔버(21)와 제2챔버(22)가 오일공급유로(23)를 매개로 서로 연결되어진다.The oil pressure transmitted to the chamber 31 passes through the communication hole 34 toward the second chamber 22, whereby the first chamber 21 and the second chamber 22 open the oil supply passage 23. Are connected to each other by means of

상기와 같이 제1챔버(21)와 제2챔버(22)가 연결됨으로써 오일펌프는 제1챔버(21)의 공간에서 제1챔버(21) + 제2챔버(22)의 공간으로 토출 공간을 확장하게 되고, 이러한 토출공간의 확장은 더 많은 오일을 배출하면서도 오일압은 낮춰주는 작용을 하게 된다.As described above, since the first chamber 21 and the second chamber 22 are connected, the oil pump discharges the discharge space from the space of the first chamber 21 to the space of the first chamber 21 + the second chamber 22. This expansion of the discharge space serves to lower oil pressure while discharging more oil.

그러므로, 본 실시예에 따른 오일펌프는 엔진의 회전수 상승시에 과도한 오일압이 형성되는 것을 방지함으로써 엔진 과부하도 방지될 수 있게 된다.Therefore, the oil pump according to the present embodiment can be prevented from overloading the engine by preventing excessive oil pressure from being formed when the engine speed increases.

도 3(다)는 엔진의 회전수가 더욱 상승됨에 따른 가변스프링(10)의 작용으로 아우터링(4)의 연결링(4a)도 더욱 밀려남으로써, 아우터링(4)의 궤적변화가 더욱 진행되어진 상태이다.3 (c) shows that the connection ring 4a of the outer ring 4 is further pushed by the action of the variable spring 10 as the engine speed is further increased, thereby further changing the trajectory of the outer ring 4. It is a state.

상기 아우터링(4)의 궤적에 변화에 따른 연결링(4a)의 위치 이동은 압력연동체(30)의 위치 이동을 발생시키게 되고, 이로 인해 피스톤(32)의 "┏" 단면 오일경로(32a)와 오일공급유로(23)가 서로 어긋나 챔버(31)에는 더 이상 오일압이 작용하지 않게 된다.The positional movement of the connection ring 4a according to the change in the trajectory of the outer ring 4 causes the positional movement of the pressure interlocking body 30, which causes the "32" end face oil path 32a of the piston 32. ) And the oil supply passage 23 are shifted from each other so that the oil pressure no longer acts on the chamber 31.

그러므로 가변스프링(10)의 초기 상태 복귀로 아우터링(4)의 궤적이 다시 복귀될 때 까지 오일펌프는 제1챔버(21)쪽에서 만 유량을 토출하는 상태를 유지하게 된다.Therefore, until the trajectory of the outer ring 4 is returned to the initial state return of the variable spring 10, the oil pump maintains a state of discharging the flow rate only from the first chamber 21 side.

상기와 같이 본 실시예에 따른 2단 가변 오일펌프는 일정 이상의 엔진 회전수 상승시 오일 토출공간을 제1챔버(21)의 공간에서 제1챔버(21) + 제2챔버(22)의 공간으로 확장하고, 이러한 토출공간 확장을 이용해 더 많은 오일을 배출하면서도 오일압은 낮춰 엔진 과부하도 방지될 수 있게 된다.
As described above, in the two-stage variable oil pump according to the present embodiment, the oil discharge space is increased from the space of the first chamber 21 to the space of the first chamber 21 + the second chamber 22 when the engine speed is increased by a predetermined level or more. By expanding the discharge space, the oil pressure is lowered while the oil is discharged, and the engine overload can be prevented.
