Abstract

The invention provides a fluid pipeline for fluid circulation, which can improve the airtightness of the partition wall without reducing the accuracy of the size and shape of the orifice provided in the partition wall. The partition wall (10) of the fluid line (1) is formed by joining the upper partition wall part (11) and the lower side partition wall part (12) by welding. The lower partition wall part (12) has a joint side part (13) and an orifice side part (wall part 31), and a joint part (19) with the upper partition wall part (11) is provided on the joint side part (13). ), on the other hand, the orifice (32) is provided on the orifice side portion, so that the joint (19) and the orifice (32) are arranged at positions deviated from the joint direction.

Description

technical field

[0001] The present invention relates to fluid lines for communicating fluids. Background technique

[0002] Among the fluid lines, there is a line configured to divide the fluid passage by a partition wall, and restrict the flow of the fluid by an orifice provided in the partition wall. For example, Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2016-114035) discloses a device in which, in an oil separator installed in a vehicle such as an automobile, a section is provided on a partition wall provided in a blow-by gas flow path. The orifice separates the oil from the blow-by gas by blowing the gas accelerated by the orifice to the opposing substrate.

[0003] Patent Document 1: Japanese Patent Laid-Open No. 2016-114035

[0004] However, in the device of this patent document 1, since the partition wall is attached to the fluid line by fitting using the attachment groove, the airtightness of the partition wall (blocking the upstream...
