Embodiment
Core of the present utility model is to provide a kind of pressurized machine, reliability when this pressurized machine can improve the motion of exhaust gas bypass valve.Another core of the present utility model is to provide a kind of automobile that comprises above-mentioned pressurized machine.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further detailed.
As in Figure 2-4, the utility model embodiment provides a kind of pressurized machine, it comprises volute 21, final controlling element, push rod 22, lining 23, crank 24 and exhaust gas bypass valve 25, on volute 21, there is suction port, relief opening and bypass air outlet, between suction port and relief opening, be communicated with exhaust passage, between exhaust passage and bypass air outlet, be communicated with bypass air flue, exhaust gas bypass valve 25 is arranged on bypass air flue, and the connected sum of controlling bypass air flue with this is closed.Final controlling element and push rod 22 are fixing, and one end of push rod 22 and crank 24 are rotationally connected, and crank 24 is set in lining 23, has matching gap between the two, and lining 23 is fixed on volute 21, and crank 24 fixes with exhaust gas bypass valve 25.During pressurized machine work, when needs are communicated with or close bypass air flue, final controlling element can drive push rod 22 to move, and then driving crank 24 is in the interior rotation of lining 23, exhaust gas bypass valve 25 can rotate in bypass air flue, with this, realizes the connection of bypass air flue or closes.
One of improvement of the present utility model is, on the internal surface of volute 21, there is waste gas diversion division 211, this waste gas diversion division 211 is with respect to outstanding setting of internal surface of volute 21, along exhaust gas flow direction, the top of waste gas diversion division 211 is higher than one end of the internal surface of close volute 21 in aforementioned matching gap, and waste gas diversion division 211 is positioned at the upstream of exhaust gas flow direction, exhaust gas flow direction herein refers to the flow direction of the waste gas that can contact with waste gas diversion division 211 while flowing, for example, along the mobile waste gas of the internal surface of volute 21.
Waste gas in volute 21 is when flowing in the matching gap between lining 23 and crank 24, a part of waste gas wherein will act on mutually with waste gas diversion division 211, this waste gas diversion division 211 can stop that waste gas further flows in the matching gap between lining 23 and crank 24, and then minimizing enters the exhausted air quantity in above-mentioned matching gap.Obviously, than the content of introducing in background technique, the pressurized machine that the utility model embodiment provides has slowed down the corrosion to lining 23 and crank 24 of waste gas in volute 21, so that crank 24 is not easy to occur catching phenomenon while rotating, so raising be connected with crank 24 25 motion of exhaust gas bypass valve time reliability.
While specifically arranging, the face contacting with waste gas on above-mentioned waste gas diversion division 211 can extend along the normal direction of waste gas diversion division 211, but under this kind of mode, after waste gas and 211 effects of waste gas diversion division, can there is larger collision, cause waste gas diversion division 211 to be subject to larger impact force.The impact force being subject in order to reduce waste gas diversion division 211, with this, extend the life-span of waste gas diversion division 211, the face that flows into a side towards waste gas on the waste gas diversion division 211 that the utility model embodiment provides is guide surface, this guide surface is with respect to the normal direction of waste gas streams Inbound, to the downstream inclination of waste gas streams Inbound.Visible, after waste gas contacts with above-mentioned guide surface, under the effect of guide surface, striking force between the two can be decomposed in different directions, then reduces the impact force that waste gas diversion division 211 is subject to.
On waste gas diversion division 211, towards the surface of a side of aforementioned matching gap, can be arbitrary structures form, but in practical work process, understand some waste gas and directly act on waste gas diversion division 211 towards the surface of a side of aforementioned matching gap, and then enter in above-mentioned matching gap.For this reason, on the utility model embodiment waste gas diversion division 211, towards the surface of a side of aforementioned matching gap, be set to arc shaped surface, one end near lining 23 on this arc shaped surface has water conservancy diversion cambered surface, and the water conservancy diversion direction of this water conservancy diversion cambered surface is away from the matching gap between lining 23 and crank 24.Accordingly, act on waste gas diversion division 211 the lip-deep waste gas towards a side of aforementioned matching gap, will under the effect in water conservancy diversion cambered surface, flow to the side away from above-mentioned matching gap, and then reduce to a greater degree the amount that flows into the waste gas in this matching gap.
Further, the one end that is positioned at volute 21 on lining 23 has water conservancy diversion plane, this water conservancy diversion plane is positioned on the outer surface of institute's lining 23, and the matching gap between lining 23 and crank 24 be positioned at water conservancy diversion plane bearing of trend away from side, should refer to waste gas away from a side of aforementioned matching gap away from side.Above-mentioned water conservancy diversion plane also can flow in the matching gap between lining 23 and crank 24 by stop portions waste gas, while especially thering is above-mentioned water conservancy diversion cambered surface on waste gas diversion division 211, water conservancy diversion plane can be docked with water conservancy diversion cambered surface along the water conservancy diversion direction of water conservancy diversion cambered surface, make waste gas be directed to more reliably the position away from aforementioned matching gap, with this, prevent that to a greater degree crank 24 from catching phenomenon occurring while rotating.
Understandably, lining 23 easily deforms in hot environment, and the position especially contacting with volute 2, when lining 23 deforms, easily cause the matching gap between lining 23 and crank 24 to diminish, there will be equally crank 24 that the situation of clamping stagnation occurs when rotating.The surface coordinating with volute 21 on lining 23 is defined as to outer surface, in order to address the above problem, outer surface comprises first surface and second of being connected with this first surface, second inner side near volute 21, and the distance between the axis of second and lining 23 is less than the distance between first surface and the axis of lining 23, be the external diameter that the external diameter of first surface is greater than second, make to there is deformation gap between second and volute 21.Particularly, the second face can be curved surface, also can be plane, for the ease of processing, and provides uniform deformation space, and the utility model embodiment the second face is set to plane.
Adopt after a upper technological scheme, even if lining 23 deforms, deformation gap between itself and volute 21 also can make the distortion of lining 23 extend into the direction near volute 21, while preventing lining 23 distortion with this, press to crank 24, and then the matching gap between lining 23 and crank 24 is more easily kept.
The automobile that the utility model embodiment provides comprises pressurized machine, and this pressurized machine is the described pressurized machine of above-mentioned arbitrary technological scheme.Because above-mentioned pressurized machine has above-mentioned technique effect, the automobile that comprises this pressurized machine also should have corresponding technique effect, repeats no more herein.
Only by the mode of explanation, some one exemplary embodiment of the present utility model has been described above, undoubtedly, for those of ordinary skill in the art, in the situation that not departing from spirit and scope of the present utility model, can to described embodiment, revise by various mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claim protection domain.
