Description

そこで、この発明は、上述不都合を除去するために、エンジンのピストンに向けてオイルを噴射するオイルジェットを備え、このオイルジェットの上流側のオイル通路に連絡するオイル流量調整装置を備えるオイル供給装置において、前記オイル流量調整装置はオイル入口とオイル出口とを備える外筒部と、この外筒部の中を摺動可能に配置され、前記オイル入口と前記オイル出口とを連通させる開放位置と前記オイル入口と前記オイル出口とを非連通させる閉鎖位置とに移動して切り替える可動弁と、この可動弁を開放位置か閉鎖位置のいずれかに付勢する弾性部材と、前記外筒部と前記可動弁との間に配置され、前記エンジンの吸気系に連通する圧力室とを備え、吸気圧力の変化に応じて前記可動弁を開放位置か閉鎖位置のいずれかに作動させて前記オイル通路を流れるオイル流量を調整することを特徴とする。 Accordingly, in order to eliminate the above-described disadvantages, the present invention includes an oil supply device that includes an oil jet that injects oil toward the piston of the engine, and an oil flow rate adjustment device that communicates with an oil passage on the upstream side of the oil jet The oil flow rate adjusting device is provided with an outer cylinder portion having an oil inlet and an oil outlet, and an open position in which the oil inlet and the oil outlet are communicated with each other, and is slidably disposed in the outer cylinder portion. A movable valve that moves and switches to a closed position where the oil inlet and the oil outlet are not communicated, an elastic member that urges the movable valve to either the open position or the closed position, the outer cylinder portion, and the movable And a pressure chamber that communicates with the intake system of the engine, and the movable valve is operated in either an open position or a closed position according to a change in intake pressure. It is allowed and adjusting the oil flow through the oil passage.

エンジンのピストンに向けてオイルを噴射するオイルジェットを備え、このオイルジェットの上流側のオイル通路に連絡するオイル流量調整装置を備えるオイル供給装置において、前記オイル流量調整装置はオイル入口とオイル出口とを備える外筒部と、この外筒部の中を摺動可能に配置され、前記オイル入口と前記オイル出口とを連通させる開放位置と前記オイル入口と前記オイル出口とを非連通させる閉鎖位置とに移動して切り替える可動弁と、この可動弁を開放位置か閉鎖位置のいずれかに付勢する弾性部材と、前記外筒部と前記可動弁との間に配置され、前記エンジンの吸気系に連通する圧力室とを備え、吸気圧力の変化に応じて前記可動弁を開放位置か閉鎖位置のいずれかに作動させて前記オイル通路を流れるオイル流量を調整することを特徴とするオイル供給装置。 An oil supply apparatus comprising an oil jet that injects oil toward a piston of an engine, and an oil flow adjusting device that communicates with an oil passage upstream of the oil jet, wherein the oil flow adjusting device includes an oil inlet, an oil outlet, An open cylinder position that is slidably disposed in the external cylinder section, and that allows the oil inlet and the oil outlet to communicate with each other, and a closed position that does not allow the oil inlet and the oil outlet to communicate with each other. A movable valve that is moved and switched, an elastic member that urges the movable valve to either the open position or the closed position, and the outer cylinder portion and the movable valve. A pressure chamber communicating therewith, and adjusting the flow rate of oil flowing through the oil passage by operating the movable valve in either an open position or a closed position in accordance with a change in intake pressure. Oil supply device, characterized in that. 前記吸気圧力として負圧が印加され、所定の圧力より負圧が大きい時は、前記弾性部材の付勢力に打ち勝って負圧で前記可動弁が作動し、前記オイル通路を閉じ、一方、所定の圧力より負圧が小さい時は、前記弾性部材で付勢されて前記可動弁が作動し、前記オイル通路を開くことを特徴とする請求項１に記載のオイル供給装置。   When a negative pressure is applied as the intake pressure, and the negative pressure is larger than a predetermined pressure, the movable valve is operated with the negative pressure to overcome the urging force of the elastic member, and the oil passage is closed. 2. The oil supply device according to claim 1, wherein when the negative pressure is smaller than a pressure, the movable member is urged by the elastic member and the oil passage is opened. 前記吸気圧力として正圧が印加され、所定の圧力より正圧が低い時は前記弾性部材で付勢されて前記可動弁が作動し、前記オイル通路を閉じ、一方、所定の圧力より正圧が大きい時は、前記弾性部材の付勢力に打ち勝って正圧で前記可動弁が作動し、前記オイル通路を開くことを特徴とする請求項１に記載のオイル供給装置。   A positive pressure is applied as the intake pressure, and when the positive pressure is lower than a predetermined pressure, the elastic member biases the movable valve to close the oil passage, while the positive pressure is increased from the predetermined pressure. 2. The oil supply device according to claim 1, wherein when it is large, the movable valve is operated with a positive pressure by overcoming the biasing force of the elastic member to open the oil passage.
