Description of drawings
Fig. 1 is the plan structure scheme drawing of the band semi-sictional view of the utility model embodiment;
Fig. 2 is the construction profile scheme drawing of the utility model embodiment.
The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
The specific embodiment
In conjunction with illustrated in figures 1 and 2, the novel liquid charge pump of present embodiment comprises a base plate 1, fix a valve pocket 2 on the base plate 2, valve pocket 2 is provided with an inlet point and is the discharging opening (not shown) that a deflection angle is provided with inlet point, be provided with spool 3 in the described valve pocket 2, described spool 3 connects one and drives the rotary cylinder 4 that spool 3 rotates, described base plate 1 is provided with slide rail 5, rotary cylinder 4 is installed on the described slide rail 5, described rotary cylinder 4 connects the screw mandrel 6 that a driven in rotation cylinder 4 slides on described slide rail 5, screw mandrel 6 connects a stepping motor 7, the described valve pocket 2 outer steel bushings 8 that are provided with, described steel bushing 8 be provided with valve pocket 2 on inlet point and corresponding liquid inlet joint 9 of discharging opening and fluid joint 10.In the present embodiment, rotary cylinder 4 comprises exterior fixed part and the rotatable portion of in-to-in, and exterior fixed part is connected with screw mandrel, and it is reciprocating only to be responsible for driving integral body, does not participate in controlling the spool rotation, the rotation of rotatable control of in-to-in spool.
For the ease of the installation of parts, described base plate 1 two ends are respectively equipped with two first adapter plate 11 and second adapter plates 12 perpendicular to base plate 1, and described stepping motor 7 is installed on first adapter plate 11, and described steel bushing 8 is installed on second adapter plate 12.Be connected by a coupler 13 between described stepping motor 7 and the screw mandrel 6.In described herein first adapter plate 11 and second adapter plate 12 first and second nothing specifically refers to meaning, only is used to distinguish a plurality of same parts, is convenient to describe.
Because valve pocket 2 and spool 3 in use need the lubricity that keeps good, for the ease of keeping the lubricated of valve pocket and spool, the described steel bushing of present embodiment 2 is outer to be provided with a profit cup 14 that is used for lubricated valve pocket 2 and spool 3, can be as adding lubricating fluid between valve pocket 2 and the spool 3 by profit cup 14.
