HYDRAULIC TANK AND METHOD OF MANUFACTURING HYDRAULIC TANK Russian patent published in 2020 - IPC F15B1/26 F16N19/00 B29C41/04 B29D22/00 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic tank for storage of hydraulic fluid. Proposed hydraulic tank for storage of hydraulic fluid comprises solid housing (12), which forms plastic hollow body and is made by rotational molding. At that, tank housing (12) has at least one connecting hole (92, 94, 126), in which connection element (100, 109, 110, 132, 134, 136, 138, 140) is located, made with possibility of detachable connection to hydraulic pipeline. At that, connecting element (100, 109, 110, 132, 134, 136, 138, 140) contains plastic body made by means of plastic molding under pressure and welded to tank body (12). In tank housing (12) there is filter system (27). At that, tank housing (12) has hole (36) for filter access, surrounded by edge area (34) of said housing (12), wherein to edge section (34) is welded filter housing (46) inserted into housing (12) of tank through said hole (36). At that, the filter housing is made in the form of a plastic body by means of plastic injection under pressure.

EFFECT: technical result is higher mechanical strength of tank housing, as well as increased reliability and resource of filter operation.
