2. Design casing right-hand member face cross-section is left side concave arc, when guaranteeing casing diapire self intensity, accessible casing right-hand member face retraction reduces the shared space of whole pump case again, reduces its requirement to installation space to improve the practicality of pump case.
3. Strengthen the strip both can be used to strengthen cell body diapire intensity, can strengthen registration arm intensity again, that is to say, strengthen the strip and possess a dual-purpose effect of thing, strengthen like this under the prerequisite of pump case installation stability, still possess simple structure's advantage.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in figure 1, the pump shell of the automobile brake pump comprises a barrel-shaped shell 1, and the left end and the right end of the shell 1 are respectively in an open shape and a closed shape. Two oil inlets 1a and two oil outlets 1b are arranged on the side wall of the shell 1, the oil inlets 1a and the oil outlets 1b are both communicated with the inner cavity of the shell 1, and the oil inlets 1a and the oil outlets 1b alternate along the axial direction of the shell 1.
As shown in fig. 2 and 3, an annular seat 1c is integrally formed on the outer side wall of the left end of the housing 1, and the annular seat 1c and the housing 1 are coaxially arranged. The annular seat 1c is provided with bolt holes 1c1 penetrating along the axial direction of the shell 1, and at least two bolt holes 1c1 are uniformly distributed along the circumferential direction of the shell 1. Preferably, the number of bolt holes 1c1 is 4.
