Embodiment
Below, use Fig. 1 ~ 4, just the 1st example of the present invention is described.In the hydraulic pressure installation of Fig. 1, valve component is inner valve group 13 and external valve group 14, is configured in storage tank 12 side respectively.This hydraulic pressure installation, such as, as shown in Figure 4, the driving oil sucked from storage tank 12 by an oil hydraulic pump 20 is linked cylinder 101,102 through inner valve group 13 and external valve group 14, an above-mentioned oil hydraulic pump 20 drives by motor 11 and is used as pressurised oil to be supplied to the hydraulic power in 2 cylinders 101,102, above-mentioned inner valve group 13 has bleeder valve 38 and switching valve 35 etc., further, said external valve group 14 has the supply of subtend 2 cylinders 101,102, discharges the oily switching valve 34,36,37 carrying out switching of driving.These inner valve groups 13 are connected by pipe arrangement 15 with external valve group 14.In addition, in order to governing speed, be provided with floater controlled valve 39 and throttle valve 40, and bleeder valve 38 makes driving liquid return storage tank 12 and arrange.
Further, inner valve group 13, with motor 11 and oil hydraulic pump 20 in the lump as internal structure part, is surrounded with enclosing cover 16,16-1,16-2 by storage tank 12.And external valve group 14 is fixed on storage tank 12.Further, connect the pipe arrangement 15 of inner valve group 13 and external valve group 14, as shown in FIG. 2 and 3, be disposed in storage tank 12 inner, ining succession two valve groups 13,14 respectively in its two ends, also can connect storage tank 12 and two valve groups 13,14 with pipe arrangements such as flexible pipes.And as shown in Figure 3, external valve group 14 also can be surrounded by sheet material 17 and enclosing cover 18, and is fixed on storage tank 12, and pipe arrangement is also formed at sheet material 17.
About the making method of this storage tank 12, be produce the storage tank main body 12 and storage tank lid with pipe arrangement 15 respectively by die casting after, fixing and form storage tank 12 with bolt etc.And, while the pipe arrangement 15 driving liquid is set, the wiring hole 19 of distribution is set equally, can through the distribution of the electronic signal of the switching valve and motor for driving inner valve group 13.In addition, while being provided with pipe arrangement 15 and wiring hole 19, also on the mating face of storage tank main body 12A side and storage tank lid 12B side, be provided with the sealing materials such as O type ring, drive oil to prevent from being mixed into.
Secondly, when driving above-mentioned hydraulic pressure installation, if make contactor 31 work, then motor 11 rotates, and the oil hydraulic pump 20 connecting motor 11 and rotatingshaft rotates.Oil hydraulic pump 20 sucks liquid from storage tank 12, and is supplied by liquid to inner valve group 13 and external valve group 14.If oil hydraulic pump 20 switches switching valve 34 while rotating, then externally the A port conveying of valve group 14 is by hydraulic fluid, and the cylinder 101 be connected by flexible pipe is thus expanded.Secondly, if oil hydraulic pump 20 switches switching valve 36 while rotating, then externally B, C port conveying of valve group 14 is by hydraulic fluid, and the cylinder 102 that the relation flexible pipe due to pressure difference is connected is expanded.
And if oil hydraulic pump 20 switches switching valve 37 while rotating, then to B port feed drive liquid, the cylinder 102 be connected by flexible pipe is thus shunk.Further, if switch switching valve 35, then cylinder 101 shrinks because of deadweight, drives liquid to turn back to storage tank 12 from A port through floater controlled valve 39.
In addition, in the above-described embodiments, as shown in Figure 3, the pipe arrangement 15A of storage tank main body 12A side and the pipe arrangement 15B of storage tank lid 12B side passes through O type engagement of loops at respective end face, as shown in Figure 5, also can use the pipe arrangement 15C for connecting in addition, pipe arrangement 15A, 15B are joined to one another.
In addition, the present invention also comprises variant embodiment as shown in Figure 6, makes inner valve group 13 integrated with external valve group 14, and its feature is that valve is combined as 1.Even if in such an embodiment, the pipe arrangement of connecting fluid press pump 20 and valve group, the same with shown in Fig. 2, Fig. 3 and Fig. 5, is located at storage tank 12 inner, thus can the miniaturization of implement device and lighting, thus reduce costs, further, owing to not exposing pipe arrangement, so can not pipe arrangement be damaged, and do not need unnecessary space, therefore can obtain what is called and the special effect being applicable to the hydraulic pressure installation be arranged on vehicle can be provided.
