Embodiment Construction

[0014] Below, refer to figure 1 as well as figure 2 One embodiment of a double tank type oil pan will be described.

[0015] Such as figure 1 As shown, a cylinder block 1 of an internal combustion engine is provided with a crankshaft 2 and an oil discharge passage 3 . In addition, an oil pan 4 is assembled to a lower portion of the cylinder block 1 . The oil pan 4 has a shape in which the distance between the opposing inner walls 10 becomes narrower toward the lower portion. A box-shaped spacer 5 with an upper opening is assembled inside the oil pan 4 . The spacer 5 is formed of resin.

[0016] The interior of the oil pan 4 is divided by a partition 5 into an inner tank 6 and an outer tank 7 . The inner tank 6 is provided with an oil filter 8 for absorbing accumulated oil. In addition, the inner tank 6 communicates with the outer tank 7 through a communication hole 9 provided on the side wall of the spacer 5 . In addition, the spacer 5 is provided with a flange 11 pro...

Abstract

The present invention provides an oil pan. The double-slot type oil pan includes: a resin-made spacer which divides the inside of the oil pan into an inner tank and an outer tank; a plate; and an elastically deformable sealing member, The sealing member is provided on the plate, and is in close contact with the inner wall of the oil pan to seal the outer groove. The plates and spacers are fastened together.

Description

technical field [0001] The present invention relates to a double-slot oil sump having an inner tank and an outer tank. Background technique [0002] Conventionally, there is known a double-slot type oil pan that includes a spacer assembled inside and has an inner tank and an outer tank divided by the spacer. For example, refer to Patent Document 1. In such an oil pan, after the engine is started, only the engine oil stored in the inner tank is circulated to rapidly increase the temperature of the engine oil, thereby reducing friction at the lubricating parts. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2011-226394 [0004] However, lubricating the internal combustion engine and the temperature-raised engine oil flows down the inner wall of the cylinder block. And, if the engine oil that flows down in this way flows into the outer tank, the amount of the engine oil that returns to the inner tank decreases. Therefore, the temperature rise of the engine oil in...
