    • A body (2) of an oil jet (100) is provided with: an oil supply port (6) which opens into an oil passage (62) in a cylinder block (60) of an internal combustion engine; a cylinder (4) one end of which is communicated with the oil supply port (6) and the other end of which is closed; and an oil injection port (10) which opens on a side surface of the cylinder (4). A piston valve (20) is accommodated in the cylinder (4). The piston valve (20) forms in the cylinder (4) a differential pressure room (8) which is a closed compartment. Moreover, an orifice (22) which makes the differential pressure room (8) being communicated with a side of the oil supply port (6) is formed in the piston valve (20). The piston valve (20) is biased toward a position at which the oil injection port (10) is closed by a spring (14). Furthermore, a leak hole (42) which allows oil to be leaked outside of the body (2) from the differential pressure room (8) is formed in the body (2).
    • 油喷射器体(2)设置有:通向内燃机的气缸体(60)内的油路(62)的供油口(6); 一个气缸(4),其一端与供油口(6)连通,另一端关闭; 和在气缸(4)的侧面开口的注油口(10)。 活塞阀(20)容纳在气缸(4)中。 活塞阀(20)在气缸(4)中形成作为封闭隔室的差压室(8)。 此外,在活塞阀(20)中形成有使差压室(8)与供油口(6)的一侧连通的孔口(22)。 活塞阀(20)被朝向油注入口(10)被弹簧(14)关闭的位置偏压。 此外,在主体(2)中形成有允许油从压差室(8)泄漏到主体(2)外部的泄漏孔(42)。

    • A piston cooling jet includes a housing, a nozzle, a valve, a pressure chamber, a pressure adjusting passage, and a filter. The nozzle is provided to project outward from the housing, and capable of spraying oil toward a piston. The valve is capable of moving reciprocally inside the housing, and configured to receive a load due to a hydraulic pressure in an engine-side oil passage applied from a front side of the valve. The valve includes a valve-side oil passage that communicates with the engine-side oil passage. The pressure chamber communicates with the valve-side oil passage. The pressure adjusting passage is disposed between the pressure chamber and a space outside the housing. The filter is disposed in the valve, and configured to remove foreign matter that cannot pass through the pressure adjusting passage from oil passing through the valve-side oil passage.
    • 活塞冷却喷射器包括壳体,喷嘴,阀,压力室,压力调节通道和过滤器。 喷嘴设置成从壳体向外突出,并且能够向活塞喷油。 阀能够在壳体内往复运动,并且构造成由于从阀的前侧施加的发动机侧油路中的液压受到负载。 阀包括与发动机侧油路连通的阀侧油路。 压力室与阀侧油路连通。 压力调节通道设置在压力室和壳体外部的空间之间。 过滤器设置在阀中,并且构造成从通过阀侧油路的油除去不能通过压力调节通路的异物。
