Embodiment Construction

[0010] The specific implementation will be described in detail below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, this embodiment consists of a split housing (1), a filter element (20) arranged inside the housing (1), a filter element support (3) and a check valve (4). The check valve (4) ) is arranged on the upper end of the inner cavity of the filter element holder (3), the check valve (4) includes a base (41), a hemispherical valve cover (42), a return spring (43) and a spring seat (44), the The hemispherical bonnet (42) is arranged on the central hole (45) of the base (41), the spring seat (44) and the base (41) are detachably threaded and the return spring (43) is pre-compressed The rear is arranged between the spring seat (44) and the base (41), and the spring seat (44) is a closed type. During use, the pressure oil overcomes the spring force of the return spring (43) to push back the hemispherical valve cover (42), and flows from ...

Abstract

The invention discloses a combined oil filter, which relates to an oil filter. In order to solve the problem that a check valve and the oil filter are fixed into a whole in the prior art, the invention provides a combined oil filter, which comprises a split shell (1), a filter element (20) arranged in the shell (1), a filter element bracket (3) and a check valve (4); the check valve (4) is arranged at an upper end of an inner cavity of the filter element bracket (3); the check valve (4) comprises a base (41), a hemispherical valve cap (42), a return spring (43) and a spring seat (44); the hemispherical valve cap (42) is arranged on a centre hole (45) of the base (41); the space between the spring seat (44) and the base (41) are removable threaded connection, and the return spring (43) after precompression is arranged between the spring seat (44) and the base (41); and the spring (44) is a closed type spring. In breakdown maintenance, the check valve of the oil filter only needs to rotate the spring seat (44) to the opposite direction to open the threaded connection between the spring (44) and the base (41).

Description

technical field [0001] The invention relates to an engine oil filter. Background technique [0002] The function of the oil filter is to filter the oil entering the main oil passage of the engine, so that the oil can reach a certain degree of cleanliness, and prevent the early abrasive wear of the moving parts in the engine due to impurities. If the oil filter is installed upside down, it is necessary to install a check valve for the oil filter to ensure that the oil in the main oil passage reaches the normal working pressure as soon as possible after the engine is started. The check valve of the oil filter is connected in series with the filter in the lubricating system. When the engine stops working, the check valve closes to prevent the loss of engine oil from the oil inlet of the filter and ensure that the main The oil in the oil circuit reaches the working pressure. In the existing oil filter, the check valve is fixed with the filter as a non-detachable integrated str...
