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
The present invention relates to a kind of oil filter.
Background technology
The effect of oil filter is that the machine oil that enters the engine main oil gallery is carried out filtering, makes machine oil reach certain cleannes, prevents each moving component in the engine because impurity causes early stage abrasive wear.Be inverted under the situation of installing in oil filter, then need fitting machine oil rectifier check-valves, behind engine start, reach normal operating pressure as early as possible to guarantee the machine oil in the main oil gallery.The oil filter check-valves is connected with cleaner in lubricating system, and closure of check ring when engine quits work stops machine oil to run off from the cleaner oil-in, guarantees when engine starts once more that the machine oil in the chien shih working connection reaches operating pressure when the fastest.In the existing oil filter, check-valves all is fixed as the integrative-structure of non-disconnectable formula with cleaner.Though check-valves was still intact when disposable filter was discarded, also can only discard, and caused waste thereupon.
Summary of the invention
For solving in the prior art check-valves and the oil filter existing drawback that is solidified as a whole, the invention provides a kind of combined oil filter.
Technical scheme of the present invention is as follows: it comprises split type housing (1), be arranged on the inner filter core (20) of housing (1), filter core support (3) and check-valves (4), described check-valves (4) is arranged on the upper end of filter core support (3) inner chamber, described check-valves (4) comprises base (41), hemispherical valve gap (42), return spring (43) and spring base (44), described hemispherical valve gap (42) is arranged on the centre bore (45) of base (41), between spring base (44) and the base (41) for removable be threaded and described return spring (43) precommpression after be arranged between spring base (44) and the base (41), described spring base (44) is a closed.
As a further improvement on the present invention, be removable being threaded between described spring base (44) and the base (41).
Further improve as of the present invention, described filter core support (3) comprises that overhead gage (31), sidewall have the newel (32) and the lower baffle plate (33) of oil through, and described base (41) is fixed with one with the lower baffle plate (33) of filter core support (3).
The check-valves of oil filter of the present invention when breakdown maintenance, only needs rotating missile spring abutment (44) and base (41) round about, and spring base (44) can be thrown off with base (41), and is easy to operate.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention;
Fig. 2 is check-valves of the present invention (4) and filter core support (3) assembling schematic diagram;
The specific embodiment
Specify the specific embodiment below in conjunction with Figure of description.
As shown in Figure 1, present embodiment is by split type housing (1), be arranged on the inner filter core (20) of housing (1), filter core support (3) and check-valves (4) are formed, described check-valves (4) is arranged on the upper end of filter core support (3) inner chamber, described check-valves (4) comprises base (41), hemispherical valve gap (42), return spring (43) and spring base (44), described hemispherical valve gap (42) is arranged on the centre bore (45) of base (41), between spring base (44) and the base (41) for removable be threaded and described return spring (43) precommpression after be arranged between spring base (44) and the base (41), described spring base (44) is a closed.In the use, the spring force that pressure oil overcomes return spring (43) backs down hemispherical valve gap (42), from machine oil whorl of base oil return opening flow direction engine.When engine quit work, return spring (43) falls after rise closed hemispherical valve gap (42), and machine oil can be deposited in the oil filter.When engine starts once more,, make the machine oil in the working connection reach operating pressure with the minimum time.
Preferably, be removable being threaded between described spring base (44) and the base (41), described valve gap (42) is a hemispherical.
More preferably, the outer wall of described spring base (44) is provided with the protruding circle of ring-type (47), and the center hole wall of described filter core support (3) is provided with the projection (34) suitable with the protruding circle of ring-type (47).
Still more preferably, described filter core support (3) comprises that overhead gage (31), sidewall have the newel (32) and the lower baffle plate (33) of oil through, and described base (41) is fixed with one with the lower baffle plate (33) of filter core support (3).
By above-mentioned illustrative embodiments as can be known, technical scheme of the present invention is not limited thereto.For the one of ordinary skilled in the art, under the situation that does not break away from flesh and blood of the present invention, use needs as long as satisfy, all in protection scope of the present invention.
