Embodiment
See also Fig. 1 to Fig. 3, can know in figure and find out that hydraulic pressure installation of the present utility model comprises housing 1, transmission shaft 2, unilateral bearing 3, rotor 4 and a plurality of blades 5, wherein:
This housing 1 is cylindrical body, its inside has the flowing space 11, housing 1 is provided with to be communicated with the feed pathway 12 and liquid outlet channel 13 of the flowing space 11, feed pathway 12 and liquid outlet channel 13 are arranged at housing 1 both sides, and feed pathway 12 is arranged on housing 1 with tangent direction, allow the flowing space 11 of fluid in this housing 1 form annularly flow, wherein, the above-mentioned flowing space 11 defines pressure stage 111 in feed pathway 12 towards the direction of liquid outlet channel 13, and the flowing space 11 defines decompression section 112 at liquid outlet channel 13 towards the direction of feed pathway 12.
This transmission shaft 2 is arranged in housing 1, and is positioned at the place, axle center of housing 1 flowing space 11.
This unilateral bearing 3 is sheathed with transmission shaft 2, in order to according to the unidirectional turn of transmission shaft 2.
This rotor 4 is sheathed on unilateral bearing 3, and rotor 4 external annulus are arranged with a plurality of grooves 41.
This blade 5 is located at the groove 41 of rotor 4, the accommodating blade 5 of each groove 41, blade 5 radially is free state along this rotor 4, blade 5 one distal process stretch out groove 41, the other end is near groove 41 bottoms and mineralization pressure space 7, and each end of blade 5 that stretches out the groove 41 of rotor 4 tiltedly is provided with inclined-plane 51.
see also Fig. 2 to Fig. 4, before the utility model uses, in advance with the transmission shaft 2 connection for transmission system (not shown) of hydraulic pressure installation of the present utility model, and feed pathway 12 and liquid outlet channel 13 are connected respectively to use and carry and the oil pressure that produces circulation produces the machine (not shown) for fluid, when the utility model when using, because feed pathway 12 is arranged on housing 1 with tangent direction, therefore when fluid enters the flowing space 11 by feed pathway 12, (fluid flow direction is as shown in Fig. 3 filled arrows) can form an annularly flow, fluid characteristics can produce thrust to each blade 5 near feed pathway 12, because of groove 41 width of rotor 4 greater than blade 5 thickness, allow fluid produce thrust to each blade 5, promote blade 5 one sides and form towards groove 41 1 sides the state that supports, and allow the side surface of blade 5 opposite sides form runner 6 with the side surface interval of groove 41 opposite sides, allow fluid enter pressure space 7 along runner 6, in order to improve the hydraulic pressure of pressure space 7, can form thrust (as shown in Fig. 3 solid arrow) to blade 5 bottoms, promote again blade 5 and move and form towards housing 1 inwall the state of supporting, allow fluid produce hydraulic pressure to blade 5 side surfaces that stretch out groove 41, can be in pressure stage 111 place's drive rotor 4 turns of the flowing space 11, produce kinetic energy.
wherein, when rotor 4 continues turn, partial blade 5 enters the decompression section 112 of the flowing space 11, because of the close liquid outlet channel 13 of this partial blade 5, the fluid of making way for these blade 5 peripheries enters in liquid outlet channel 13 immediately, make the hydraulic pressure that acts on these blade 5 side surfaces ineffective and produce release of pressure immediately, at this moment, fluid in pressure space 7 namely flows out (as shown in Fig. 4 dotted arrow) by runner 6, and then the interior hydraulic pressure of reduction pressure space 7, to allow blade 5 move towards groove 41 bottoms, simultaneously, blade 5 breaks away from housing 1 inwall the state that supports, in order to reduce the frictional force of blade 5 and housing 1 inwall.
