Description of Invention (ί) The present invention relates to a short joint of an oil pump installed in the suction port or first-class outlet of a lubricating oil pump. More specifically, the present invention relates to a short joint * of an oil pump, which prevents the short joint from moving relative to the pump housing. In order to understand the present invention, the typical conventional oil pump that feeds lubricating oil to the engine, and the twelfth to eighteenth figures are described below. Figure 12 is a cross-sectional view of a conventional oil pump that feeds lubricating oil to an engine (not shown), and Figure 13 is a cross-sectional view of the oil pump along line A-A in Figure 12. A cylinder 2 is formed inside a pump casing 1 and a plunger 3 is provided in the cylinder 2 to rotate and reciprocate linearly. A single suction port 4 and two outlets 5 communicating with the cylinder 2 are formed on the pump casing 1, and a short joint 6 with a curved portion of the wheel gallery at an appropriate angle is installed at the suction port 4 at an intermediate position With such outflow 5. When the plunger 3 rotates and reciprocates linearly, lubricating oil is introduced into the pump casing 1 from the suction port 4, and then discharged to the outside through the outflow ports 5. As shown in the twelfth and thirteenth figures, when the plunger 3 makes one revolution, it will reciprocate linearly twice. However, the plunger 3 is not limited to this type. The short joints 6 are here pseudo-made of a material of gold, such as brass or the like. Due to the recent need to gradually reduce the size of the engine oil pump, the size of the pump housing 1 is reduced, resulting in the distance between the suction port 4 or the outlet port 5 and the cylinder 2 being forced to be reduced. This creates a problem. When the short joints 6 made of gold alloy are pressed into the pump casing 1 * the cylinder 2 will be deformed, resulting in the rotary movement of the plunger 3 and linear reciprocation Poor movement. In practice, if the size of this paper is between the center of the cylinder 2 and the center of each first-class export 5, the Chinese National Standard (CNS) A4 specification (210X297 mm) is applicable ---------- ^ Shiyi-- (Please read the precautions on the back before filling in this page) Order m305909 A7 B7 Printed by the Ministry of Economic Affairs Central Bureau of Customs and Industry Beigong Consumer Cooperatives 5. The distance D (as shown in Figure 13) of the invention description (z) is equal to or When the short joints 6 made of metal material are pressed into the pump housing 1, the cylinder 2 will be deformed so that the plunger 3 does not move well. Therefore, the distance d between the center of the suction port 4 and the end face of the cylinder 2 (as shown in the twelfth figure) is shorter than the distance D, and when the short joints 5 made of the material of gold are pressed together When entering the pump casing 1, the cylinder 2 will undergo significant deformation. In order to solve the above-mentioned problem that the cylinder 2 is greatly deformed, it may be considered that the short joint 6 is made of synthetic resin instead of a metal material. The short joint 6 made of synthetic resin is also in the same way as the short joint made of metal material. • There is a vertically curved wheel bend in the middle. In order to maintain the closed state of the short joint 6 made of synthetic resin when it is installed in the suction port 4 or the outflow port 5, an O-ring 7 is surrounded on the joint body. In addition, a ring-shaped engaging claw 8 protruding outward is formed on the outer side wall of the joint body near the foremost end, and the foremost end is pseudo-inserted into the suction port 4 or the outflow port 5. In addition, most of the grooves 9 are pseudo-formed on the short joint 6 and extend axially across the engaging claw 8 from the insertion end of the suction port 4 or the outlet port 5. In this way, the grooves 9 are formed in such a way that the diameter of the engaging claw δ can be elastically reduced when the short joint 6 is inserted into the suction port 4 or the outflow port 5, and then the short joint 6 is completely inserted into the When the suction port 4 or the discharge port 5 is engaged, the engaging claw 8 can be elastically opened. On the other hand, a stepped wall 10 is formed on the bottom side of the suction port 4 or the outflow port 5. When the engaging claw 8 of the short joint 5 is inserted into the suction port 4 or the outflow port 5 of the pump body 1, the engaging claw δ is engaged with the stepped wall 10 of the pump housing 1, so It is possible to prevent the short joint 6 from being separated from the suction port 4 or the outflow port 5.

Invention Description (5) A flange portion 11 protruding outward from the outer side wall of the pump housing 1 is formed on the short joint 6 and is located between the engaging claw 8 and the bent portion of the joint body. The flange portion 11 acts as a stopper for preventing the short joint 6 from being further inserted into the suction port 4 or the outflow port 5. Because the positional closure between the short joint made of synthetic resin and the pump housing 1 cannot be maintained (as shown in the twelfth and thirteenth figures), when the short joint 6 is subjected to a strong external force, the short joint 6 will not be able to position on the pump shell skull 1. For this reason * it is necessary to provide a device to hold the short joint δ on the pump housing 1 in a proper direction. Figures 14 to 16 show a short joint with a device for maintaining the proper positional relationship between the pump casing 1 and the short joint. The same accessories in the fourteenth to sixteenth figures as in the twelfth and thirteenth figures are indicated by the same reference symbols. A pipe connecting portion 13b is formed on the outer peripheral surface of a short joint 12 made of synthetic resin, and is located near the opening portion on the opposite side of the engaging claw 8 for connecting an oil pipe 13a to the pipe connecting portion 13b. As shown in the fourteenth to sixteenth figures, a pin-shaped mounting protrusion 14 extending in the downward direction is integrally formed on the flange portion 11. On the other hand, as shown in FIG. 17, a hole 16 is formed on the end face 15 of the opening of the outflow port 5 formed on the pump casing 1 so that the mounting protrusion 14 can be mounted on the hole 16 Inside. When the short joint 12 is inserted into the outflow port 5, the mounting protrusion 14 and the short joint 12 are mounted in the hole 16 of the pump housing 1. When the mounting protrusion 14 is mounted in the hole 16 in this way, the tube connection portion 13b of the short joint 12 is held at a position relative to the pump casing 1 in a predetermined direction. One tube connection part 13b of the short joint 12 is inserted into the suction -7-This paper · Standard is applicable to China National Standard (CNS) A4 specification (21〇x297mm) (Please read the precautions on the back before filling this page ) \ | Installed. Booked, printed by Ai B7 in the Beigong Consumer Cooperation of Central Bureau of Standards of the Ministry of Economy V. Invention description (Ping) Port 5 is held in a proper direction in the same way as above. Therefore, its description is omitted. Of it. Fig. 18 is a perspective view showing another structure of a pipe connecting portion 13b holding a short joint 17 in a predetermined direction. An engaging protrusion 18 with a radial protrusion is integrally formed on the short joint 17. On the other hand, two protrusion-like engaging members 19 are integrally formed on the pump housing 1 to hold the opposite side surface of the engaging protrusion 18 between the two protrusion-like engaging members 19. When the short joint 17 is inserted into the outflow port 5, the engaging protrusion 18 of the short joint 17 is clamped between the two engaging members 19. This causes the tube connection portion 13b of the short joint 17 to be held in a predetermined direction. As shown in the fourteenth to seventeenth figures, due to the short joint 17, the width of the annular end face 15 at the opening of the suction port 4 or the outlet port 5 will be smaller due to the design of the pump housing 1 Shrinkage causes the diameter of the hole 16 to shrink accordingly. In addition to this, the diameter of the pin-shaped mounting protrusion 14 mounted in the hole 16 is also reduced. In this way, when the oil pipe 13a is connected to the pipe connecting portion 13b of the short joint 12 in a press-fit manner, if the short joint 12 is subjected to a great rotational force, there will be a problem that the pin-shaped mounting protrusion 14 will be damaged due to the rotation force, so that the tube connection portion 13b of the short joint 12 cannot be held in a predetermined direction. In addition, since the pin-shaped mounting protrusion 14 is formed on the short joint 12 in one piece, another problem arises, that is, the hole 16 is the required direction on the pipe connection portion 13b of the short joint 12 each time When changing, it is necessary to re-boring the ring end face 15 with the narrower opening. The short connector 17 of the blue in the eighteenth picture, because it can be integrated into the sudden paper size, is suitable for the Chinese National Standard (CNS) Α4 specification (210Χ297 mm) (Read the precautions on the back first and fill in this page) Installed, ιτ appealed to A7 _ B7_____ printed by the Beigong Consumer Cooperative of the Central Department of Economics of the Ministry of Economic Affairs. 5. Description of Invention (Dead) The width of the connecting protrusion 18 on the edge 11 becomes larger, so the short joint 17 has enough The strength can resist the rotation force received by the short joint 17. However, * when the required direction of the tube connecting portion 13 changes, a new mold needs to be manufactured * to keep the short joint 17 in the direction corresponding to the extension of the engaging protrusion 18. This leads to high manufacturing costs for new molds. The present invention is made based on the background described above. An object of the present invention is to provide a short joint * of an oil pump which can ensure that when a great rotational force is applied to one of the joints of the short joint, the joint of the short joint will not be damaged and malfunction. Another object of the present invention is to provide a short joint of an oil pump, which can ensure that a pipe connection portion of the short joint can be correctly held in a predetermined direction at low cost. According to the present invention, it provides a short joint of an oil pump made of synthetic resin * The short joint of the oil pump includes a mounting device provided at one end of the pump for the short joint to be installed in the suction port or outflow port, here, The short joint is composed of two members, one is like a directional member, the directional member has a mounting hole and an engaging protrusion formed on the other, and the other is a joint body * The joint body has a mounting wall The part can be installed in the installation hole, the installation device is provided on the joint skeleton * A flange part is formed to hold the orientation member between the pump casing skeleton and the joint body in a clamped state, and A pair of engaging members are formed on the pump housing to hold the engaging protrusion. When the mounting hole formed in the orienting member pivots about its center at a predetermined angle equal to or less than 100 degrees * The position of the mounting hole before rotation and the position after rotation are consistent.

Description of Invention (?) Between 19 pieces. Since the orientation member 22 is held at a position where it will not rotate relative to the joint body 21, it is closed. Therefore, when the engagement protrusion 24 is located between the pair of engagement members 19, the joint skeleton 21 will not face each other. The pump housing 1 rotates. This prevents the joint 20 from rotating around the centerline of the outlet 5. According to the present invention, since the engagement protrusion 24 is wider and the pair of protruding engagement members 19 is thicker> the engagement protrusion 24 or the engagement member 19 will not break when in the engaged state phenomenon. The shape of the mounting hole 23 formed on the orientation member 22 is not limited to the aspect shown in the second and third figures. The mounting hole 23 can be of any type other than circular. For example, the shape of the mounting hole 23 may be a polygonal shape as shown in the fourth to sixth figures, or a cross shape as shown in the seventh figure. The fourth to seventh figures show that the mounting hole 23 has the same shape when the orientation member 22 is rotated around the center point of the mounting hole 23 by 45 degrees, 60 degrees, 90 degrees, etc. In other words > The orientation member 22 is installed on the engagement protrusion. The installation position of the outlet portion 24 can be changed with respect to the joint main skeleton 21. In this way, the tube connecting portion 13b of the short joint 20 can be oriented substantially toward the direction in which the oil pipe 13a is disposed. The shape of the directional member 22 can be as shown in the fourth to tth figures, as shown in the eighth and ninth figures. It can be used for the short joint 20, but the position where the orientation member 22 is installed in the installation hole 23 cannot be changed. According to the present invention, if the positional relationship between the tube connection portion 13b of the short joint 20 and the pump housing 1 can be adjusted and changed, only the orientation member 22 can be replaced with another orientation eaves member. For example, if the positional relationship between the mounting hole 23 and the connecting protrusion 24 is changed from the positional relationship shown in the third figure to the tenth figure-13-This paper scale is applicable to the Chinese National Standard (CNS) A4 specification ( 210X297mm) (Please read the precautions on the back before filling in this page). Binding. Order A7 B7 printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy A synthetic resin is injection molded, or it is manufactured by stamping a gold plate with a stamping machine. In this way, it can be ensured that the orientation member 22 in which the extending direction of the pipe connecting portion 13b coincides with the extending direction of the oil pipe 13a can be manufactured with less cost. As shown in the first figure, there is only one passage for the lubricating oil to pass through, and the passage is pseudo formed inside the joint body 21. However, as shown in Fig. 11, a check valve 27 may be installed in the connector body 22 to prevent the backflow of lubricating oil. Since the check valve 27 has a conventional structure, it will not be described here. The above-mentioned means for preventing the rotation of the joint body around the center line of the outlet 5 is not limited to the structures shown in the first and second figures. For example, the structure may also be a hole penetrating the engaging protrusion 24 formed in the orientation member 22, and the orientation member 22 has a wider width and a pin (not shown) standing on the pump housing 1 so that The pin is inserted into the hole to prevent the joint skeleton 21 from rotating. As described above, since the short joint is composed of the joint body and the orientation member provided separately, if the position of the pipe connection portion of the short joint and the pump housing can be adjusted and changed, only the orientation member can be replaced. It's enough. In this way, the short joint can be adjusted and changed direction with less cost. Since the thickness of the plate forming the directional member and the size of the width of the connecting protrusion are not limited, the directional member can be designed to have greater strength. In this way, when the short joint is connected to the oil pipe, the orientation member may be damaged due to the external force applied thereto, and further, the positional relationship between the short joint and the pump housing can be maintained. According to the present invention, since the short joint is composed of two components, that is, one is the joint skeleton, and g- is the directional component, the directional portable component can be installed on the -14.
