Abstract
The utility model relates to a single blade oil pump, which is composed of a pump body (1), a rotating shaft (2), and a sliding blade (7), wherein, the inner cavity of the pump body (1) is composed of a circle arc surface (3) with a major diameter, a circle arc surface (4) with a minor diameter, and two transitional arc surfaces (5); the upper part of the pump body (1) is provided with an oil inlet (8) and an oil outlet (9); the rotating shaft (2) is installed on the pump body (1); the sliding blade (7) is installed in a through hole groove (6) which is arranged on the rotating shaft (2). Because only using one sliding blade, the utility model has the advantages of simple structure, big oil supply, higher working pressure, and reliable operation.
Description
The utility model relates to a kind of single vane oil pump, belongs to the oil pump field.
At present, oil pump of the prior art mainly contains two kinds of gear oil pump and vane oil pumps, and the shortcoming of gear oil pump is that complex structure, fabricating cost height, flow are little; And the shortcoming of vane oil pump also is that complex structure and working pressure are little, and because the blade of vane oil pump is many, its blade is easy to stuck and damages.
The purpose of this utility model is: provide that a kind of simple in structure, fuel delivery is big, working pressure is higher, the more reliable single vane oil pump of work.
The utility model is to constitute like this: it is by the pump housing (1), rotating shaft (2) sliding blade (7) is formed, the inner chamber of the pump housing (1) is by large diameter circular arc face (3), minor diameter arc surface (4) and two sections transition cambered surfaces (5) are formed, an oil inlet hole (8) and an oil outlet (9) are arranged on the pump housing (1), rotating shaft (2) is passed the inner chamber of the pump housing (1) and is contained on the pump housing (1), in the rotating shaft (2) of the pump housing (1) inner chamber part, a through-hole groove (6) is arranged, sliding blade (7) is housed in through-hole groove (6), the length of sliding blade (7) is the same with the interior cavity length of the pump housing (1), and its width is the same with the pump housing (1) intracavity diameter.
The utility model compared with prior art, owing to only used a slice sliding blade, and the two ends of sliding blade the time contacts with the inner chamber of oil pump all the time in work, thus the utlity model has simple in structure, fuel delivery is big, working pressure is higher, the reliable advantage of work.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the A-A sectional view of accompanying drawing 1;
Accompanying drawing 3 is the schematic perspective view of the utility model rotating shaft (2).
Embodiment of the present utility model: with the inner chamber large diameter circular arc face (3) of the pump housing (1), minor diameter arc surface (4) and two sections transition cambered surfaces (5) are formed, this four arcs face is when making, it is the same to guarantee that the center of circle by the minor diameter circular arc arrives the length of all straight lines at inner chamber two ends, go up a making oil inlet hole (8) and an oil outlet (9) at the pump housing (1), the inner chamber that rotating shaft (2) is passed the pump housing (1) is contained on the pump housing (1), and make its shaft axis concentric with the center of circle of minor diameter arc surface, in the rotating shaft (2) of the pump housing (1) inner chamber part, open a through-hole groove (6), in through-hole groove (6), put into sliding blade (7), the length of sliding blade (7) is the same with the interior cavity length of the pump housing (1), and its width is the same with the pump housing (1) intracavity diameter.
Claims (1)
1, a kind of single vane oil pump, it comprises the pump housing (1), rotating shaft (2), it is characterized in that: the inner chamber of the pump housing (1) is by large diameter circular arc face (3), minor diameter arc surface (4) and two sections transition cambered surfaces (5) are formed, an oil inlet hole (8) and an oil outlet (9) are arranged on the pump housing (1), rotating shaft (2) is passed the inner chamber of the pump housing (1) and is contained on the pump housing (1), in the rotating shaft (2) of the pump housing (1) inner chamber part, a through-hole groove (6) is arranged, sliding blade (7) is housed in through-hole groove (6), the length of sliding blade (7) is the same with the interior cavity length of the pump housing (1), and its width is the same with the pump housing (1) intracavity diameter.
