Description

Drain valve for engine lubricating oil filter

The present invention relates to a vehicle oil strainer drain valve to allow the oil to be automatically discharged when the element is removed from the filter of the engine oil lubricating and cooling while circulating inside the engine of the vehicle.

The drain valve of a conventional engine oil filter consists of a case having an oil inlet and an oil outlet through which the filtered oil exits, an element housed inside the case, and a lid screwed to the case.

The case is made of aluminum die-casting, the outlet body connecting the oil outlet and the oil gallery and the inlet passage having an inlet passage for connecting the oil inlet and the oil pump, and is installed at the inlet end of the inlet passage, If foreign substances are caught in the filter medium by using the non-return valve and the element for long time prevention, the oil filtration performance of the filter medium decreases, and the oil discharge to the oil outlet is significantly reduced compared to the oil inlet of the oil inlet. It is composed of a relief valve to prevent it, especially in the case of an element exchange type vehicle oil filter, since the oil remains in the case when the element is replaced, the large amount of oil is buried together with the element. Causing waste of oil and inserting elements Edo oil overflowed from the case, it was inefficient during replacement work, wasted oil, and inconvenient for the operator. One part of the pressurizes the drain valve to block the drain inlet, and upon removal of the element, the drain valve opens to allow oil to flow out into the oil tank.

However, in the case of the conventional drain valve, it consists of two stoppers for limiting the movement distance of the protrusion and the stopper for limiting the movement distance of the sealing seat, and its function is complicated. In the case of the primary spring and the secondary spring, the element is inserted at the time of insertion. When the primary spring is pressed, touches the stopper, the secondary spring is pressed, and when the lid of the case is opened, only the secondary spring acts to push the element, so that the inertia force of the spring is not completely transmitted to the element. The element is missing, there was a problem that the weak side occurs.

Therefore, the present invention for solving the above problems is that when the replaceable element 70 is inserted, the primary spring 50 and the secondary spring 51 are pressed at the same time, the seating portion 30 in contact with the sealing sheet 20 When the drain inlet 23 through which the oil is discharged should be blocked, and the lid of the case is opened, the primary spring 50 and the secondary spring 51 of the primary spring 50 and the secondary spring 51 are automatically pushed out. The elastic force is exerted on the exchangeable element 70 at the same time, the element 70 is automatically raised up at the same time the oil through the drain pipe 80, to provide a drain valve for a vehicle oil filter for the action of the oil is discharged.

Features of the present invention for achieving the above object,

The seating portion 30 and the protrusion 40 are fastened in the sealing sheet 20 so that the oil moves along the drain pipe 80, and between the seating portion 30 and the stopper 41 extending below the protrusion 40. The secondary spring 51 is fastened to, and the primary spring 50 is fastened to the protrusion jaw 42 and the sealing seat 20 on the outer side of the stopper of the protrusion 40. And the elastic tension of the primary spring 50 is weaker than the secondary spring 51, so that the protrusions 40 simultaneously press the two springs, but in fact the primary spring 50 is pressed before the secondary spring 51, When the lid of the case is opened, the elastic force of the primary spring 50 and the secondary spring 51 is applied to the element 70 at the same time, so that the tension of the spring is automatically maintained without the action of the other force exerted by the exchangeable element 70 at this part. It is characterized by being pushed up.
