Description

Fluid adjustment structure

This invention is a fluid throttling structure. Specifically, it is a fluid regulating structure used in motorcycles.

Figure 1A is an exploded schematic diagram of a learned throttle valve and an electric idle motor. Figure 1B is an exploded schematic diagram of a learned throttle valve and a manual idle motor. The only difference between Figures 1A and 1B is that Figure 1A uses an electric idle motor, while Figure 1B uses a manual idle motor. The electric idle motor in Figure 1A is used as an example for illustration. Referring to Figure 1A, the idle motor 200' has a truncated tapered portion 210' that is used to move back and forth through a flow port 130' between a first chamber 110' and a second chamber 120' of the throttle valve 100', thereby controlling the flow rate (or flow velocity) of a fluid (e.g., oil) from the first chamber 110' to the second chamber 120' through the flow port 130'.

Figure 3 is a cross-sectional diagram of the learning throttle valve and the electric idle motor in Figure 1A in a high flow state. Figure 4 is a cross-sectional diagram of the learning throttle valve and the electric idle motor in Figure 1A in a low flow state. As shown in Figure 3, when the truncated conical portion 210' of the idle motor 200' is away from the flow port 130', a large amount of fluid (e.g., oil) can flow from the first chamber 110' through the flow port 130' to the second chamber 120' according to the path P1'. This represents a high flow rate. As shown in Figure 4, when the truncated conical portion 210' of the idle motor 200' partially passes through the flow port 130', the fluid (e.g., oil) is partially blocked at the flow port 130'. Consequently, only a small amount of fluid can flow from the first chamber 110' through the flow port 130' to the second chamber 120' according to the path P2'. This represents a low flow rate.

Due to the tapered design of the truncated conical portion 210' of the idle motor 200', it is easy for the truncated conical portion 210' to completely block the flow port 130', rendering the idle motor 200' inoperable and preventing fluid flow, thereby affecting the engine's operation and the motorcycle's driving. Furthermore, as shown in Figures 1A (and 1B) and 2, since the idle motor 200' and the throttle valve 100' are connected by only a single sealing ring (e.g., O-ring 300'), fluid can easily squeeze the O-ring 300', causing deformation or slippage, leading to oil leakage.

Based on the above reasons, one objective of this invention is to disclose a fluid regulation structure. By configuring a flow inlet, a flow space, and a flow outlet, fluid can be directed from a portion of the flow inlet and/or the flow outlet into the flow space, and then out through another portion of the flow outlet. By adjusting the first area of the flow outlet in the first chamber and the second area of the flow outlet in the second chamber, the flow rate of fluid flowing out of the second area of the flow outlet can be stably regulated, thereby preventing blockage of the flow port and affecting the engine's ignition and driving of the motorcycle. The structure is applicable to both manual and electric idle motors.

Another objective of this invention is to disclose a fluid conditioning structure that securely seats a sealing ring (e.g., an O-ring) in an annular groove on the idle motor's retaining platform, preventing excessive fluid pressure from causing the sealing ring (e.g., O-ring) to deform or slip, leading to oil leakage.

To achieve the above objectives, the present invention provides a fluid regulating structure comprising a throttle valve having a first chamber and a second chamber interconnected, with a flow opening defined between the first and second chambers; and an idle motor movably disposed within the first chamber. The idle motor comprises at least one fluid regulating member movably disposed through the flow opening. The fluid regulating member comprises a body, a flow inlet, a flow space, and a flow outlet. The flow inlet is disposed at an end of the body proximate the first chamber. The flow space is disposed within the body and communicates with the flow inlet. The flow outlet is disposed on a side of the body and communicates with the flow space. The relative position of the flow outlet and the flow opening regulates the flow rate of a fluid flowing from the first chamber to the second chamber.

In some embodiments, the idle motor is a manual idle motor or an electric idle motor, and the idle motor further has a stop platform that is blocked at an end of the second chamber away from the flow port.

In some embodiments, an annular groove is provided on an outer periphery of the stop platform for receiving an O-ring plug.

In some embodiments, the body of the fluid conditioning member is a hollow cylinder, the flow inlet of the fluid conditioning member is an open end of the hollow cylinder, the flow guiding space of the fluid conditioning member is a hollow portion of the hollow cylinder, and the flow guiding outlet of the fluid conditioning member is an opening disposed on the outer side of the hollow cylinder.

In some embodiments, the opening is in the shape of an elongated strip, and an axial direction of the opening is parallel to an axial direction of the main body.

In some embodiments, the body of the fluid conditioning member is fork-shaped, the fluid diversion inlet of the fluid conditioning member is an open end of the fork, the fluid diversion space of the fluid conditioning member is located within the fork of the fork, and the fluid diversion outlet of the fluid conditioning member is located on the side of the fork of the fork.

In some embodiments, the body of the fluid conditioning member is a half-cut hollow cylinder, the flow guide inlet of the fluid conditioning member is an open end of the half-cut hollow cylinder, the flow guide space of the fluid conditioning member is the hollow portion of the half-cut hollow cylinder, and the flow guide outlet of the fluid conditioning member is the half-cut open portion of the half-cut hollow cylinder.

In some embodiments, when the fluid regulating member is closer to the first chamber, a first area of the diversion outlet portion in the first chamber is larger than a second area of the diversion outlet portion in the second chamber, with the flow opening as the boundary, and the fluid flows from the first chamber into the second chamber at a relatively low flow rate.

In some embodiments, when the fluid regulating member is farther from the first chamber, a first area of the diversion outlet portion in the first chamber is smaller than a second area of the diversion outlet portion in the second chamber, with the flow port as the boundary, and the fluid flows from the first chamber into the second chamber at a higher flow rate.

In some embodiments, the half-cut hollow cylinder is vertically cut or obliquely cut.

Figure 5B is an exploded schematic diagram of another embodiment of the fluid adjustment structure of the present invention. Figure 6 is a partially enlarged cross-sectional schematic diagram of the idle motor in the fluid adjustment structure of the present invention in Figure 5A. Figure 7 is a cross-sectional schematic diagram of the fluid adjustment structure of the present invention in Figure 5A.

Referring to Figures 5A, 5B, and 7, the fluid regulating structure 10 of the present invention may include a throttle valve 100 and an idle motor 200.

The throttle valve 100 may include a first chamber 110 and a second chamber 120 that are interconnected. In some embodiments, a flow port 130 may be provided between the first chamber 110 and the second chamber 120.

The idle motor 200 is movably disposed within the first chamber 110. In some embodiments, the idle motor 200 may be a manual idle motor (as shown in FIG. 5A ) or an electric idle motor (as shown in FIG. 5B ), but is not limited thereto.

In some embodiments, the idle motor 200 may have at least one fluid regulating member 210. The fluid regulating member 210 may movably pass through the flow port 130.

In some embodiments, the fluid conditioning member 210 comprises a body 211, a flow inlet 212, a flow guiding space 213, and a flow outlet 214. The flow inlet 212 is disposed at one end of the body 211 near the first chamber 110. The flow guiding space 213 is disposed within the body 211 and communicates with the flow inlet 212. The flow outlet 214 is disposed on a side of the body 211 and communicates with the flow guiding space 213. The relative position of the flow outlet 214 and the flow port 130 regulates the flow rate of a fluid (e.g., oil) from the first chamber 110 to the second chamber 120. In some embodiments (i.e., the first embodiment of the fluid conditioning member 210 of the idle motor 200 of the present invention), the body 211 of the fluid conditioning member 210 may be a hollow cylinder, the flow inlet 212 of the fluid conditioning member 210 may be an open end of the hollow cylinder, the flow guiding space 213 of the fluid conditioning member 210 may be the hollow center of the hollow cylinder, and the flow outlet 214 of the fluid conditioning member 210 may be an opening (e.g., an oblong hole, a rectangular hole, etc.) disposed on the outer side of the hollow cylinder.

Figure 10A is a schematic 3D diagram of another embodiment of an idle motor in the fluid adjustment structure of the present invention. Figure 10B is a schematic 3D diagram of another embodiment of an electric idle motor in the fluid adjustment structure of the present invention. Referring to Figure 10A , in some embodiments (i.e., the second embodiment of the fluid adjustment member 210 of the idle motor 200 of the present invention, where the idle motor 200 is a manual idle motor), the body 211 of the fluid adjustment member 210 may be fork-shaped, the flow inlet 212 of the fluid adjustment member 210 may be an open end of the fork, the flow diversion space 213 of the fluid adjustment member 210 may be the interior of the fork's split, and the flow diversion outlet 214 of the fluid adjustment member 210 may be the side of the fork's split. Please refer to Figure 10B again. Its structure is similar to that of Figure 10A. The only difference is that the idle motor 200 in Figure 10B is an electric motor. Therefore, the same structural parts will not be described again.

FIG11A is a perspective view of another embodiment of a fluid regulating member for an idle motor in the fluid regulating structure of the present invention. FIG11B is a perspective view of another embodiment of an electric idle motor in the fluid regulating structure of the present invention. Referring to FIG. 11A , in some embodiments (i.e., the third embodiment of the fluid adjustment member 210 of the idle motor 200 of the present invention, where the idle motor 200 is a manual idle motor), the body 211 of the fluid adjustment member 210 may be a half-cut hollow cylinder, the half-cut hollow cylinder being vertically cross-sectioned. The flow inlet 212 of the fluid adjustment member 210 may be an open end of the half-cut hollow cylinder. The flow guide space 213 of the fluid adjustment member 210 may be the hollow portion of the half-cut hollow cylinder. The flow outlet 214 of the fluid adjustment member 210 may be the open portion of the half-cut hollow cylinder. Please refer to Figure 11B again. Its structure is similar to that of Figure 11A. The only difference is that the idle motor 200 in Figure 11B is an electric motor. Therefore, the same structural parts will not be described again.

Figure 12A is a schematic perspective view of yet another embodiment of a manual idle motor in the fluid adjustment structure of this invention. Figure 12B is a schematic perspective view of yet another embodiment of an electric idle motor in the fluid adjustment structure of this invention. Referring to Figure 12A , its structure is similar to that of Figure 11A , differing only in that the body 211 of the fluid adjustment member 210 in Figure 12A can be a half-cut hollow cylinder, with the half-cut hollow cylinder being obliquely cut. Furthermore, the idle motor 200 in Figure 12A is a manual idle motor, so the common structural parts will not be described again. Referring to Figure 12B , its structure is similar to that of Figure 12A , differing only in that the idle motor 200 in Figure 12B is an electric motor, so the common structural parts will not be described again.

The embodiments of the fluid regulating member 210 of the idle motor 200 in the fluid regulating structure 10 of this invention are not limited to the first, second, and third embodiments described above.

Referring back to Figures 5A, 5B, 6, and 7, in some embodiments, the idle motor 200 further includes a stopper 220. The stopper 220 can be positioned against the end of the second chamber 120 away from the flow port 130. In some embodiments, an annular groove 230 is provided around the outer periphery of the stopper 220. This groove 230 can be used to seat a sealing ring (e.g., an O-ring 300), thereby preventing excessive fluid pressure from causing the sealing ring (e.g., O-ring 300) to deform or slip, leading to oil leakage.

Figure 8 is a schematic cross-sectional view of the fluid regulating structure of Figure 5A in a high flow state. Figure 9 is a schematic cross-sectional view of the fluid regulating structure of Figure 5A in a low flow state.

Referring to Figure 8 , when the fluid regulating member 210 is farther from the first chamber 110, the first area A1 of the diversion outlet portion 214 within the first chamber 110, defined by the flow opening 130, is smaller than the second area A2 of the diversion outlet portion 214 within the second chamber 120. At this point, fluid flows from the first chamber 110 into the second chamber 120 along paths P11, P12, and P13, achieving a higher flow rate.

Referring to Figure 9 , when the fluid regulating member 210 is closer to the first chamber 110, the first area A1 of the diversion outlet portion 214 within the first chamber 110, defined by the flow opening 130, is larger than a second area A2 of the diversion outlet portion 214 within the second chamber 120. At this point, fluid flows from the first chamber 110 to the second chamber 120 along paths P21, P22, and P23 at a relatively low flow rate.

In other words, by moving the fluid adjustment member 210, the size of the first area A1 of the diversion outlet portion 214 in the first chamber 110 and the second area A2 of the diversion outlet portion 214 in the second chamber 120 can be changed, thereby adjusting the flow rate of the fluid (e.g., oil) without blocking the flow port 130.

In summary, the fluid regulating structure 10 of the present invention, through the arrangement of the fluid regulating member 210 (including the body 211, the flow inlet 212, the flow guiding space 213, and the flow outlet 214), can direct the fluid from the flow inlet 212 and/or a portion of the flow outlet 214 to the flow guiding space 213, thereby allowing the fluid to flow out from another portion of the flow outlet 214. By adjusting the flow outlet 214 at the first area A1 of the first chamber 110 and the flow outlet 214 at the second area A2 of the second chamber 120, the flow rate of the fluid flowing out of the second area A2 of the flow outlet 214 can be stably regulated, thereby preventing the flow port 130 from being blocked and affecting the engine's operation and the motorcycle's driving. Furthermore, in the fluid regulating structure 10 of the present invention, a sealing ring (e.g., an O-ring) can be securely positioned within the annular groove 230 of the retaining platform 220 of the idle motor 200, preventing excessive fluid pressure from causing the sealing ring (e.g., O-ring) to deform or slip, leading to oil leakage. This structure is applicable to both manual and electric idle motors.
