Detailed Description
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Fig. 1 schematically shows the overall structure of a fuel supply system 11 for a vehicle. The fuel supply system 11 has a fuel pump module 12 according to an embodiment of the invention. The pump housing 13 of the fuel pump module 12 is formed in a cylindrical shape having a central axis Cn. An inlet 14 is defined at one end in the axial direction of the cylindrical shape. An outlet port 15 and a return port 16 are defined at the other end in the axial direction of the cylindrical shape. The inlet 14 is formed by a pipe connection 17. A fuel pipe 19 connected to a fuel tank 18 is combined with the pipe joint 17. The outlet 15 is likewise formed by a pipe connection 21. For example, a fuel pipe 23 connected to the fuel injection device 22 is coupled to the pipe joint 21. The fuel injection device 22 faces an intake passage 26 connected to an intake passage of an engine (ENG in the drawing) 25, for example. The return port 16 is also formed by a pipe joint 27. A return pipe 28 connected to the fuel tank 18 is coupled to the pipe joint 27. The return port 16 sends fuel to a fuel tank 18. The fuel supply system 11 is mounted on a saddle-ride type vehicle such as a motorcycle.
In the fuel pump module 12, a fuel pump 31 is housed in a pump housing 13. The fuel pump 31 has a metal cylinder 32. A 1 st end surface member 33 is fitted into the 1 st end of the cylindrical body 32. A press-fit pipe (2 nd connection pipe) 35 defining the suction port 34 is integrally formed with the 1 st end surface member 33. The 1 st end surface member 33 may be molded from, for example, a hard resin material. The press-fitting pipe 35 is fixed by press-fitting to a connection passage 36 defined in the pump housing 13.
A 2 nd end surface member 37 is fitted into the 2 nd end of the cylinder 32. A connection pipe 39 defining a discharge port 38 is integrally formed with the 2 nd end surface member 37. The 2 nd end surface member 37 may be molded from, for example, a hard resin material. The connection pipe 39 is accommodated in a connection passage 41 defined in the pump casing 13. The connection pipe 39 is slidably inserted into the connection flow path 41. A seal member 42 is fitted to the outer periphery of the connection pipe 39. The seal member 42 allows the sliding operation of the connection pipe 39 and establishes the liquid-tightness of the connection pipe 39 in the connection flow path 41.
The fuel pump 31 has an impeller 43. The impeller 43 is housed in an impeller chamber 44 in contact with the 1 st end surface member 33. The impeller 43 is coupled to a rotary shaft 45. The rotor 46 of the electric motor is connected to the rotary shaft 45. The rotor 46 is surrounded by a stator 47. Rotation of the rotating shaft 45 is caused by the interaction of the rotor 46 and the stator 47. When the rotation shaft 45 rotates, the impeller 43 rotates around the axis of the rotation shaft 45. The discharge pressure is generated based on the rotation of the impeller 43.
The 1 st end surface member 33 has an air release hole 48 formed therein. The deaeration hole 48 connects the impeller chamber 44 and the housing space outside the fuel pump 31. The gas mixed in the fuel introduced into the fuel pump 31 is discharged from the degassing hole 48.
The rotor 46 describes a cylindrical orbit about the rotation axis 45. The stator 47 is arranged along a cylindrical shape in accordance with the orbit of the rotor 46. The cylinder 32 is thus formed in a cylindrical shape coaxial with the rotation shaft 45. The press-in pipe 35 and the connection pipe 39 each have a central axis parallel to the rotation axis 45. The connection passage 36 of the press-fitting pipe 35 is formed by a cylindrical space coaxial with the press-fitting pipe 35. The connection flow path 41 of the connection pipe 39 is also formed by a cylindrical space coaxial with the connection pipe 39. The "fitting direction" is defined as being parallel to the rotation axis 45.
The pump housing 13 includes a 1 st housing member 51 made of resin and a 2 nd housing member 52 made of resin. The 1 st end of the fuel pump 31 is supported by the 1 st housing member 51. The 2 nd end of the fuel pump 31 is supported by the 2 nd housing member 52. A housing space 53 for the fuel pump 31 is defined between the 1 st case member 51 and the 2 nd case member 52. The 1 st housing member 51 defines the inlet 14 and the connection flow path 36. The outlet 15 and the connection flow path 41 are defined in the 2 nd case member 52. Here, the 1 st case member 51 is formed in a bottomed cylindrical shape. A flange 51a is formed at the open end of the 1 st case member 51, and the 2 nd case member 52 is formed as a lid body overlapping the flange 51 a.
The open end 54 of the 1 st case member 51 and the open end 55 of the 2 nd case member 52 are butted against each other. Thus forming a joint surface. The joint surface has a welding region 56 over the entire circumference of the housing space 53 without interruption. The fusion between the faces forms a seal between the 1 st and 2 nd casing parts 51, 52.
A pressure regulating passage 57 branched from the connection flow path 41 is formed in the 2 nd case member 52 between the connection flow path 41 and the outlet 15. The pressure adjusting passage 57 opens into the housing space 53 at the open end 55 of the 2 nd case member 52. A pressure regulating valve 58 is incorporated in the pressure regulating passage 57. The pressure regulating valve 58 has: a valve seat 59 fixed to the pressure regulating valve body 58a fitted in the 2 nd case member 52; a spherical valve body 61 seated on the valve seat 59; and an elastic body 62 that exerts a force to press the valve body 61 toward the valve seat 59. When the pressure in the connection flow path 41 rises and exceeds the pressing pressure of the elastic body 62, the fuel flows from the connection flow path 41 into the housing space 53 through the pressure regulating valve 58.
The return port 16 is defined in the 2 nd case member 52. The return port 16 is connected to a return passage 63 that opens into the housing space 53. The return passage 63 is connected to a passage 64 defined inside the housing space 53 and outside the fuel pump 31. The 1 st end surface member 33 of the fuel pump 31 faces the end wall 51b of the 1 st housing member 51 with a space therebetween. The space thus defined between the 1 st end surface member 33 and the end wall 51b of the 1 st case member 51 is connected to the passage 64. The degassing holes 48 open into the space. Similarly, the 2 nd end surface member 37 of the fuel pump 31 faces the 2 nd housing member 52 with a space therebetween. The space thus defined between the 2 nd end surface member 37 and the 2 nd case member 52 is connected to the passage 64. The pressure regulating passage 57 opens to the space.
A rib 65 is formed on the inner surface of the 1 st case member 51 in contact with the housing space 53. The rib 65 extends in the longitudinal direction of the fuel pump 31. As shown in fig. 2, the rib 65 is formed along the occupied space of the fuel pump 31. The ribs 65 define the above-described passages 64 therebetween. The pump housing 13 is formed in a cylindrical shape coaxial with the cylinder 32 of the fuel pump 31.
A method of assembling the fuel pump module 12 is briefly described. The 1 st case member 51, the 2 nd case member 52, and the fuel pump 31 are prepared. The pressure regulating valve 58 is assembled in the 2 nd case member 52. The 1 st case member 51 and the 2 nd case member 52 may be molded from a resin material. The press-in pipe 35 of the fuel pump 31 is press-fitted into the connection flow path 36 of the 1 st housing member 51. At this time, the fuel pump 31 is inserted into the 1 st housing member 51 guided by the ribs 65. Therefore, the press-fit pipe 35 of the fuel pump 31 can easily enter the connection flow path 36 of the 1 st housing member 51. The fuel pump 31 thus pressed through the press-in pipe 35 is held in the 1 st housing member 51.
Next, the 2 nd case member 52 is fitted to the 1 st case member 51. The joining surfaces of the 1 st case member 51 and the 2 nd case member 52 may be formed with concave and convex shapes that fit into each other. The 2 nd case member 52 moves toward the 1 st case member 51 in the fitting direction parallel to the rotation shaft 45. The connection pipe 39 enters the connection flow path 41 of the 2 nd case member 52. The seal member 42 is fitted in advance in the connection pipe 39. When the joint surfaces of the 1 st case member 51 and the 2 nd case member 52 are abutted against each other, the joint surfaces are welded around the entire circumference of the housing space 53.
In the fuel pump module 12, the fuel pump 31 is accommodated in the accommodating space 53. In correspondence with the welding, good sealability is established between the open end 54 of the 1 st case member 51 and the open end 55 of the 2 nd case member 52. In forming such a structure, a welding process is used. In the welding process, the fuel pump 31 is held by the 1 st case member 51. Positioning of the fuel pump 31 and joining of the 1 st housing part 51 and the 2 nd housing part 52 are achieved. The manufacturing process is reduced. The manufacturing cost is cut down.
During assembly of the fuel pump module 12, the 1 st housing part 51 and the 2 nd housing part 52 are joined to each other. At this time, when the 2 nd case member 52 is moved in the fitting direction relative to the 1 st case member 51, the open ends 54, 55 are butted against each other, and at the same time, the connection pipe 39 of the fuel pump 31 is inserted into the connection flow path 41 of the 2 nd case member 52. The 1 st and 2 nd housing parts 51, 52 are joined and the 2 nd housing part 52 is fitted to the fuel pump 31 by 1 operation. The manufacturing process is reduced. The manufacturing cost is cut down.
In the fuel pump module 12, a press-fit pipe 35 is formed on the fuel pump 31. The press-fit pipe 35 is fixed to the connection flow path 36 defined in the 1 st case member 51 by press-fitting. The fuel pump 31 is securely fixed to the 1 st housing member 51.
In the fuel pump module 12, a connection pipe 39 is formed in the fuel pump 31. The connection pipe 39 is slidably inserted into the connection flow path 41. Therefore, even if the 1 st casing member 51 or the 2 nd casing member 52 has dimensional accuracy variation or the 1 st casing member 51 and the 2 nd casing member 52 have dimensional variation due to swelling of the fuel, the dimensional variation or variation is absorbed in accordance with the sliding operation of the connection pipe 39 with respect to the connection flow path 41. A seal member 42 is attached to the outer periphery of the connection pipe 39. The sealing member 42 maintains liquid tightness regardless of the sliding action of the connection pipe 39.
A rib 65 is formed on the inner surface of the 1 st case member 51 in contact with the housing space 53. The rigidity of the 1 st case member 51 is enhanced by the action of the ribs 65. Therefore, deformation of the 1 st case member 51 is suppressed to the maximum extent at the time of molding of the 1 st case member 51 or welding of the 1 st case member 51 and the 2 nd case member 52. Further, since the rib 65 extends along the space occupied by the fuel pump 31 in the longitudinal direction of the fuel pump 31, the rib 65 can hold the fuel pump 31 in the 1 st case member 51 during the welding operation. The working efficiency is improved.
In the fuel pump module 12, the housing space 53 sealed by welding is used as a passage 64 for the fuel discharged from the degassing hole 48. The construction of the fuel pump module 12 is simplified. In addition, the vibration and sound of the fuel pump 31 are confined in the housing space 53 sealed by welding. The leakage of vibration and sound is suppressed.
In the above embodiment, the press-fitting pipe 35 of the fuel pump 31 is press-fitted into the 1 st case member 51, and the connection pipe 39 is slidably inserted into the 2 nd case member 52, but the press-fitting pipe 35 may be press-fitted into the cap-shaped 2 nd case member 52, and the connection pipe 39 may be slidably inserted into the 1 st case member 51. In addition, although the suction port 34 of the fuel pump 31 is set to the press-fit pipe 35 and the discharge port 38 is set to the connection pipe 39 in the present embodiment, the suction port 34 may be set to the connection pipe 39 and the discharge port 38 may be set to the press-fit pipe 35 in the opposite manner. Instead of the press-fitting pipe 35, a connection pipe fixed to the connection channel 36 by a method other than press-fitting may be used.
