DESCRIPTION OF THE INVENTION: TECHNICAL FIELD This application relates to fluid extraction techniques and, more particularly, to a palm-type pump that manually withdraws fluid from a reservoir. DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the invention will be directed to a manual fueling gun that is used in conjunction with a universal oiler that dispenses lubricating fluid to a workpiece during pipe drilling and thread cutting and the like. However, it is to be understood that the preferred embodiment of the present invention is suitable for use in a wide range of industrial lubrication applications such as chemical processing applications, food service applications, and applications where it is required to manually extract fluid from a reservoir to a desired area. field. [Prior Art] Many metal working processes require some kind of lubricating fluid that is delivered to the workpiece and/or tool by a pump or similar source from a supplemental source. Examples of manual thread cutting applications, such as a tool that rotates around a fixed pipe, typically uses a ratchet head to cover the tool. Other examples include automatic and semi-automatic thread cutting operations in which the power-driven cutting device is rotated relative to one or more, the tweezer's head-tubular workpiece, such as a pipe or the like, which is loaded on the cutting 6 and prepared. Carrying one or more cutters or reamers for cutting metal from the workpiece as it rotates relative to the cutting tool. Of course: 胄 - a sufficient amount of cooling and / or lubricating fluid to prevent cutting equipment to impart high quality and precision to the workpiece is important. Providing - Flushing of work areas with fluids that can be selectively delivered under moderate pressure. Fillers, fillers and the like are also important. Oil dispensers have heretofore been provided for use with, for example, pipe threading devices for use with I27530.doc 200902156. Such an oil dispenser is available from The Ridge T〇〇1 c〇mpany 〇f Elyria, Ohio Catalogue No. 418 oiler, which contains a barrel for storing thread cutting oil; one for the barrel a removable drip tray for receiving a debris spear from the thread cutting device; separating and separating the oil for return to the oil reservoir in the tub; and a f-type plate system through The hose is connected to the barrel and can be operated by a threaded machine operator to distribute the oil to the threaded work #. Typically, the tub includes a reservoir that fluidly communicates the storage area of the tub with a manually operated pump and, preferably, a screen that filters oil extracted from the storage area during its extraction to prevent metal debris Or other materials into the manual fruit. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of a prior art pump 1 , which is well accepted and well known in the art. As indicated, the pump 1 includes a handle 12 through which the pump can be held and operated by the user; a grease nipple or tube 14, and a trigger 16, which can be manually operated through the grease nipple 14 from an associated bucket The storage oil (not shown) is distributed to a workpiece. Typically, the dish also includes an upper hook 18' through which the pump can be anchored adjacent to the work area. A soft g 20 is coupled to the component by a suitable thread. Connected to the pump, the oil is delivered to the pump 1 via the hose 20 as a response to the trigger drive. Figure 2a*2b is a cross-sectional view of the chestnut of Figure 1 in the state of the trigger "in the loose (Figure 2a) and only (Figure 2b). It can be seen in the figure that the chestnut 〇 contains - the outer casing 24 'The shape forms a handle i2 at a bottom end and a hook 18 at an upper portion. The outer casing 24 defines a fluid passage % extending between the thread 22 and the grease nipple 14. A piston member "is Within the fluid passage k26 (7), the piston member is urged generally toward the handle 12 by a spring member 30 that is urged toward the 127530.doc 200902156 as shown in the proximal end of the piston member 28. Continuing with the reference to the drawings, prior art pumps of the type described above typically include first and second one-way check valve devices 32 and 38 that can be operated in a manner well known in the art for connection via a hose 2 An oil reservoir (not shown) draws the lubricating fluid to the fluid passage 26 and sprays it through the grease nipple 14 to the workpiece. In the illustrated prior art pump 10, the check valve assemblies 32 and 38 each include a steel check valve ball 34 and 4, respectively offset from the end of the piston member 28 and the threaded coupling member 22 opposite the hose. Suitable check valve seats 36 and 42 are formed on one side of the 2 〇. The prior art pump 1 shown in the figures has the disadvantage of reducing the passage efficiency of metal debris and other particles from the reservoir and to the fluid channel to a certain extent. The metal particles are either interposed between the steel check valve balls 34, 40 and their respective ball seats 36, 42 to prevent a complete and effective fluid seal between them. It is worth observing that the upper end of the fluid passage % adjacent to the piston member 28 and in the region of the spring member 3 is relatively large compared to the remainder of the passage. This can sometimes cause difficulties in pumping the pump during initial use and reduce the ability of the pump to draw the lubricant through the hose 20 to a specific height that is beneficial to the user. More specifically, in operations such as cleaning or disassembling the apparatus, the fruit 10 using the first month's technology may be partially or completely filled with a gas such as air. In this case, the pump's ability to pump oil to a specific height through a hose is very different from the ability to fill a fluid such as an oil pump. When the piston member 28 of the pump moves between positions 127530.doc 200902156 as shown in Figures 2a and 2b, the capacity of the fluid passage 26 is regulated to cause a suction activity. The gripping machine reduces the capacity so that the lubricating fluid is drawn through the bottom check valve 38 to the fluid passage. When the trigger is released 16, the piston will be pushed by the spring 30 from the position shown in Figure 2b to the position shown. Comparing these figures, it can be seen that the capacity excluded between the piston from the fully extended position (Fig. 2a) to the fully retracted position (Fig. 2b) is for the fluid passage 26 between the two opposing check valve assemblies 32, 38. In terms of total capacity, it is comparison

A large amount of air may accumulate here, with great negative consequences for the performance of the pump. Accordingly, it is an object of the present application to provide a fluid pump of a type that is less susceptible to performance degradation caused by particles or the like remaining in the pump during normal use. Another object of the present application is to provide a type of flow that is capable of being used for the first time, regardless of whether it is used under the conditions of "drying" of air or other gases, and for the purpose of providing In normal use, the oil or other fluid can be pulled from an associated storage to a manually operated fluid injection nozzle of at least two degrees of the shoulder or waist of the user.

In addition, as shown, an introduction portion 74 is disposed adjacent to the ball seat in the coupling element % to selectively contact the check ball (10) during the operation of the fueling 50 to cause the ball to be located relative to the ball. The seat is in position to provide a preferred fluid seal between the check ball HM and the ball seat 74a. The lead-in portion 74 provides features that enhance performance. More specifically, the joint 22 of the prior art as shown in Fig. 6a has a valve seat portion 仏 and an introduction portion 23' formed - about 5 相对 with respect to the longitudinal direction thereof. The angle of incidence is eight. However, in accordance with the present invention, as shown in Figure 6b, the threaded coupling member 76 includes a spherical spherical seat 74a and is formed by a tapered surface; the inlet portion - the tapered surface 75 has a defined by the coupling member. Relative = longitudinal axis is large (four). The incident angle B. It has been found that the prior art devices shown in the figure often have the following problem: the returning ball adheres to the knot portion 23 due to the low end of the incident angle of the near ball seat region. Thus, in accordance with the present invention, an introduction portion 74 is provided in the thread, a member 76 adjacent to the ball seat 7 ... by I27530.doc - 14. 200902156 one having approximately 30. The tapered surface 75 of the incident angle B is defined such that a check ball 104 having a hardness of between about 60 D and 70 D and preferably 65 D engages the ball seat 74a in use of the pump 50 without The introduction portion 74 is adhered. Although a preferred form of the lead-in portion 74 is a tapered surface 75, other forms of lead-in portions 74 can be used, such as other structural or surface configurations or combinations of configurations in the region adjacent the ball seat 74a. The use of the check ball 104 causes the check ball 104 to be in a precise position of the ball seat 74a without causing the problem that the check ball sticks to the lead-in portion during use of the tool. Continuing with reference to Figures 3 and 4 and with additional reference to Figures 5a and 5b, the piston member 120 is preferably constructed of a plastic material defining a piston body ι 22 and a fluid output conduit 124 from which the conduit is An end 126 extends through the piston body to a proximal end 128 of the piston body. As mentioned above, a ball seat portion 130 is defined at the end 126 of the piston body 122 to receive the check ball 94 that is biased away from the ball seat by the spring member 92 of the first check valve assembly 90. At the proximal end 12 of the piston member, an outer skirt member 14 is formed, as shown, which is spaced from an inner skirt member 142. Therefore, a slit 144 is formed between the outer skirt member 14A and the inner skirt member 142. 3 and 4 show a biasing spring 110 received in a split 144 between the outer skirt member 140 and the inner skirt member 142. The preferred form of the piston member 120 provides smoother operation, enhanced resistance to wear and reduced manufacturing. In the prior art, since the metal particles contained in the oil are retained between the piston and the piston cavity, viscous or slow piston action often occurs, causing the piston to stick or encounter a large amount of resistance. In the typical prior art pistons of the type described in 127530.doc -15-200902156, the voids are tightly controlled by the process, causing problems with viscous or slow moving pistons. Nevertheless, according to the present invention, the number of times the piston is stuck or the piston is slow can be reduced by increasing the gap between the piston and the piston chamber. As noted above, the piston 120 has a plurality of rib members 136 defining an annular surface to create an effective piston outer diameter that contacts the inner surface of the bore 8. The annular rib member 136 also provides overall enhanced formability for the piston 12A. The preferred piston member 12 of Figures 5a and 5b improves the manufacturing process by using an injection molding technique while maintaining the uniform-cast wall thickness. The piston of the display technology has some dimensional tolerance difficulties. In addition, moving the annular ring seal 132 closer to the spring member (4) helps to eliminate the cutting fluid flowing from the periphery of the piston and the cylindrical cavity 8〇 in which the cutting fluid flows. In its preferred form, the outer skirt member 14() is in the shape of an annular member that generally surrounds the biasing spring no. Further, the inner skirt member 142 is in the form of a cylindrical member within the inner cylindrical hollow region 1丨2 defined by the biasing spring 110. The spring size and the size relationship of the split are specifically selected

Referring again to Figures 3 and 4, it will be appreciated that the outer sugar member 14 and the inner skirt member 142 together form a fluid displacement member that is detachable from the piston member 120 in the released position shown in Figure 3 and shown in Figure 4 Move between locations. Preferably, the fluid displacement member 15 substantially completely fills the chamber 82 when the piston is pressed against the biasing force of the spring (Fig. 4). In this manner, the fluid passage in the pump is substantially greater than the difference in the prior art when the piston is in the snap-on condition of Figure 4 and the release position in Figure 3. The fuel pump that is added to the working fluid, such as a bubble or the like, will adversely affect the efficiency of the fueling. In more detail, the gas can be compressed and the skilled artisan understands that any gas that can accumulate in the refueling process can have a negative impact on the extraction efficiency, particularly the ability to infuse the perfusion and the perfusion height. According to the pump 5 of the present invention, the volume of gas in its chamber can be reduced to an optimistic by providing the fluid displacement member 150 moving together with the piston member 12 to exclude any uncompressed capacity within the piston itself. The lowest value. Preferably, as shown above, the fluid displacement member 150 is formed integrally with the piston member 120. Nonetheless, other forms of fluid displacement members can be used. In addition to the above, as shown, the sealing member 132 is carried within a groove 134 that is moved to the extreme proximal end 128 of the piston member 120 to reduce the uncompressed capacity of the piston itself. After taking care, it should be noted that the split 144 formed between the outer skirt member 14 and the inner guide member 142 is preferably minimized such that the outer skirt member and the guide members (10), 142 are as close as possible to engage the spring. Member 92 is configured to maximize the capacity removed by the fluid displacement member (9) formed by the outer skirt member and the guide member. Continuing to refer to Figures 3-5b' In its preferred form, the cylinder 80 has a smoothing surface adapted to receive-carry the sealing member η on the groove 134: the gutter is formed in the vicinity of the piston member End 128. A plurality of guide rib members 136 are provided on the body member and secured. The length of the main body member is axially spaced. In its preferred form, the 专M M a# & μ specific rib member 13 6 has a uniform cast wall thickness of 127530.doc 17 200902156 to make the piston member easy to manufacture, such as by an injection molding process. Further to the relationship between the piston member 120 and the cylinder 8 ,, in its preferred form, the cylinder has a smoothed surface to allow the sealing member 132 to be easily manually activated therein. A polishing program can be used to smooth the roughened portion of the machining that would normally cause the annular ring seal 132 to drag. This drag tends to hinder the rebound of the piston when the trigger 60 is released. In its preferred form, the sealing member 132 is a low hardness annular ring, such as 5 5 hardness.
