Embodiment
Below, use Fig. 1～4, narrated with regard to the 1st example of the present invention.In the hydraulic pressure installation of Fig. 1, the valve component is inner valve group 13 and external valve group 14, is configured in storage tank 12 sides respectively.This hydraulic pressure installation, for example, as shown in Figure 4, to link the cylinder 101,102 through inner valve group 13 and external valve group 14 from the driving oil that storage tank 12 sucks by an oil hydraulic pump 20, an above-mentioned oil hydraulic pump 20 is driven by motor 11 and as the hydraulic power that pressurised oil is supplied in 2 cylinders 101,102, above-mentioned inner valve group 13 has bleeder valve 38 and switching valve 35 etc., and said external valve group 14 has 101,102 supplies of 2 cylinders of subtend, discharges the switching valve 34,36,37 that driving oil switches.These inner valve groups 13 link to each other by pipe arrangement 15 with external valve group 14.In addition,, be provided with floater controlled valve 39 and throttle valve 40, and bleeder valve 38 is to drive that liquid returns storage tank 12 and be provided with when circuit pressure makes during more than or equal to specified pressure for governing speed.
And, inner valve group 13, with motor 11 and oil hydraulic pump 20 in the lump as the internal structure part, surround with enclosing cover 16,16-1,16-2 by storage tank 12.And external valve group 14 is fixed in storage tank 12.And, connect the pipe arrangement 15 of inner valve group 13 and external valve group 14, as Fig. 2 and shown in Figure 3, be provided in storage tank 12 inside, its two ends two the valve groups 13,14 of ining succession respectively, also pipe arrangement such as available flexible pipe connects storage tank 12 and two valve groups 13,14.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 in storage tank 12, and pipe arrangement also is formed at sheet material 17.
About the making method of this storage tank 12, be to produce respectively after storage tank main body 12 with pipe arrangement 15 and the storage tank lid by die casting, fixing and constitute storage tank 12 with bolt etc.And, be provided with when driving pipe arrangement that liquid uses 15, the wiring hole 19 that distribution is used is set equally, can pass the distribution of the electronic signal of the switching valve that is used to drive inner valve group 13 and motor.In addition, when 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 sealing materials such as O type ring, drive oil to prevent to sneak into.
Secondly, when the above-mentioned hydraulic pressure installation of driving, as if making contactor 31 work, then motor 11 rotates, and connects oil hydraulic pump 20 rotations of motor 11 and rotatingshaft.Oil hydraulic pump 20 sucks liquid from storage tank 12, and liquid is supplied with to inner valve group 13 and external valve group 14.If when oil hydraulic pump 20 rotates switching valve 34 is switched, then carry and be subjected to hydraulic fluid, thus cylinder 101 expansions that link to each other by flexible pipe to the A of external valve group 14 port.Secondly, when rotating switching valve 36 is switched, then carry to be subjected to hydraulic fluid, because the cylinder 102 that flexible pipe links to each other that concerns of pressure difference is expanded to B, the C port of external valve group 14 as if oil hydraulic pump 20.
And, when rotating switching valve 37 is switched as if oil hydraulic pump 20, then to B port feed drive liquid, the cylinder 102 that links to each other by flexible pipe shrinks thus.And if switching valve 35 is switched, then cylinder 101 shrinks because of deadweight, drives liquid and turns back to the storage tank 12 through floater controlled valve 39 from the A port.
In addition, in the above-described embodiments, as shown in Figure 3, the pipe arrangement 15B of the pipe arrangement 15A of storage tank main body 12A side and storage tank lid 12B side passes through O type engagement of loops at end face separately, as shown in Figure 5, also can use the pipe arrangement 15C that is used to connect 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 and external valve group 14 integrated, and its feature is that valve is combined as 1.Even in this structure, the pipe arrangement that connects oil hydraulic pump 20 and valve group, with Fig. 2, Fig. 3 and shown in Figure 5 the same, be located at storage tank 12 inside, but the miniaturization of implement device and lighting thus, thereby reduce cost, and, owing to do not expose pipe arrangement, so can not damage pipe arrangement, and do not need unnecessary space, therefore can obtain what is called can provide the special effect that is fit to be installed in the hydraulic pressure installation on the vehicle.
