Be applied under the situation that fluid pressure energy is converted into mechanical energy, as shown in Figure 1, provide annular cavity by cylinder body 1 and rotor 2, be provided with dividing plate 3 in the chamber, working medium inlet 4 and sender property outlet occupy the both sides of dividing plate 3 in 5 minutes, cam 6 is a disc cam, be arranged at annular cavity inside, the same by two plate shapes, be symmetrically distributed in the thin plate 61 of annular cavity on axially, 62 form (as shown in Figure 2) with the outer side wall (being the madial wall of the circumferencial direction of cylinder body 1) of the circumferencial direction of annular cavity, the purpose that two blades 7 are set symmetrically is in order to be applied to the force balance at blade 7 axial two ends, and at thin plate 61, groove 67 between 62, under 68 the effect, blade 7 can't be separated annular cavity, and forms the pressure reduction of both sides.The center of rotation of cam 6 and rotor 2 axis coincidings, the cylinder diameter that its stroke directly makes progress more than or equal to annular cavity, in the near angle of repose 8 of cam 6 was included in more than or equal to the angle in the thickness of dividing plate 3 and axle center and with dividing plate 3, the blade that moves in this angle can be dodged dividing plate fully.Motion angle for actuating travel 10 occupy dividing plate 3 both sides in 11 minutes with motion angle for return travel, and working medium inlet 4 is contained in the motion angle for actuating travel 10, and sender property outlet 5 is contained in the motion angle for return travel 11, and far angle of repose 9 pairing profiles overlap with the annular cavity outer wall.Two blades 7 distribute symmetrically at the annular cavity inner circumference, the far angle of repose 9 of cam 6 greater than the angle between two blades 7 (and consider the influence that blade 7 thickness cause angle and might occur rise the influence of jumping phenomenon).When only having a blade 7 to be in the far angle of repose 9, annular cavity is separated into two chambers by dividing plate 3 and this blade 7, and what working medium entered the mouth 4 sides is inlet 14, and the sender property outlet side is room of outlet 15.When two blades 7 were positioned at far angle of repose 11 simultaneously, annular cavity was divided into three chambers, is respectively: inlet 14, room of outlet 15, sealing chamber 16 (as shown in Figure 3).
As shown in Figure 1, when pressure fluid working medium is entered by working medium inlet 4, under the effect of inlet 14 and room of outlet's 15 both sides pressure reduction, the blade 7 in the far angle of repose 9 is done rotary-piston motion drive rotor 2 and is rotated counterclockwise acting.As Fig. 3, when two blades 7 all were in the far angle of repose 9, sealing chamber 16 formed, in a part of pressure working medium is closed in.When blade 7 runs to cam 6 backhaul sections, under the effect of cam 6, blade 7 is along radially indentation of the guiding groove on the rotor 2, breaks away from the sealing with the annular cavity outer wall, and sealing chamber 16 is finished the pressure release operation because of disappearing with room of outlet's 15 conductings.When blade 7 enters near angle of repose 8,, dodged dividing plate 3 by complete radial compression.At the actuating travel section of cam 6, blade 7 extends radially out under the elastic force effect of spring 12.When reentering far angle of repose 9, contact driving fit, once more acting with the annular cavity outer wall.Similar with existing blade type swing cylinder, remain driving fit between the side of dividing plate 3 and the rotor 2, in the embodiment shown in fig. 1, thin plate 61,62 and dividing plate 3 driving fits or integrally formed, the end of blade 7 is embedded with Sealing, blade 7 is driving fit between dividing plate and the rotor when crossing dividing plate 3 equally, and fluid working substance can the left chamber from Fig. 1 not flow into right chamber.
As shown in Figure 3, two blades 7 of cause are when one-in-and-one-out far angle of repose 9, all the time there is a blade 7 in far angle of repose 9, to do work, structural feature (being that cross-section area, shape of cross section are identical everywhere) according to the annular piston chamber, described herein all the finger under this assumed condition under the assumed condition that the pressure working medium flow is constant in the source, load is constant, ignore influences such as cam change in resistance, pressure releasing chamber residual voltage, the rotation of rotor 2 uniform angular velocities waits moment of torsion, constant power output continuously.
Be appreciated that from Fig. 1 to Fig. 3, under the situation of having only a blade 7, and be in far angle of repose 9 when outer, working medium inlet 4 and sender property outlet 5 conductings, blade 7 both sides do not have pressure reduction, keep continuous rotation can only rely on inertia or the series connection of multistage misphase.Its output torque, output work are discontinuous, and energy loss is excessive, but also can realize continuous rotation.
Be applied under the situation that mechanical energy is converted into fluid pressure energy, as shown in Figure 4, rotor 2 is rotated counterclockwise under the situation of external power, and inlet 14 is under the effect of the blade 7 that is positioned at far angle of repose 9, volume enlarges and forms negative pressure, and normal pressure working medium is inhaled into this chamber.When two blades 7 entered cam far angle of repose 9 simultaneously, sealing chamber 16 formed, in partly normal pressure working medium is closed in; Be rotated further, blade 7 enters in the motion angle for return travel 11, and sealing chamber 16 disappears with room of outlet's 15 conductings, and the normal pressure working medium of sealing is pressed in the room of outlet 15, and this moment, the pressure of fluid can increase, and present embodiment can be as pump or compressor.
What more than set forth is that cam 6 is the cloudy cam of disc type, and driven member is the working principle of blade 7 when being located on cylinder body 1 at the cam internal motion and with dividing plate 3.
