INSTRUCTIONS: [Technical field to which the invention pertains] i The present invention mainly shows a variable pump with a cooling system cycle, especially a preferred combination of a variable pump and a gear pump. [Prior Art] ...The energy output by the hydraulic pump, through various control valves and piping to the liquid helium cylinder or hydraulic motor, is the hydraulic fluid for the media to convey the amount, the pressure required in the supply loop, so that the machinery It works. At the same time, after various conditions in the test, hydraulic fluids are the most commonly used hydraulic fluids. However, when the oil is pressed, the heat is generated by the mechanical guard. When the temperature of the tank rises, the precision of the operating machinery will decrease, the life of the parts will be reduced, the number of repairs will be increased, and the service life of the machine will be reduced. θ 苍奴图 and Figure 1 are three-dimensional and three-dimensional exploded views of a conventional variable pump with a cooling system circulating pump 9 . The variable-flow variable cooling system circulation pump 9 includes a variable pump 91 and a cooling wheel pump 92, wherein the cold gear pump 92 is coupled to the rear of the variable pump 91, the variable $91 is screwed, and the σ has a pump. After that, the cover 911 is closed, and the cooling gear pump 92 is screwed: the connection port 93' is twisted and the connection block 93 is screwed to the variable pump. The two sides of the cooling gear pump can be respectively connected with the oil pipe (the cooling gear pump is required for maintenance) First remove the tubing, no), although the millet 'can not be kissed quickly, the combination of Silin unloading h shot cooling the sauce wheel makes the length longer, this county is money H. The two pumps are on the phase, and when the length is 200918755, the length is long, and because the length of the chestnut is long, the & Therefore, the present inventors have lost the conventional knowledge, and have designed a combination of a view and a cooling gear pump that is easy to be piped and easy to install and disassemble, and is indeed a better design. SUMMARY OF THE INVENTION In the present invention, the variable pump is connected to the cooling system, and the known pump is only combined with two reductions. The volume of the pump after the combination of the volume A is not related to the two chestnuts. The design does have a lot of inconvenience. The inventor of the present invention is directed to the above-mentioned front-by-side method, and it is hoped that the solution can be surely solved by == and =: the cover book ====,", including: - even dry % text loading a change , $, strong = private gear pump. Among them, the _he# wheel material includes the body, the gear and the wire, and the _ time cover is combined with the two to be installed. By connecting 34 = this is easy to install and disassemble, and (4) equipped with a safety valve, it can avoid damage to the (four) # wheel pump. Attached to the other purpose, advantages and the description of the present invention. Excerpt (4) will be detailed from 200918755 [Embodiment] The relevant functions of this book are taken, the effect of the hand, and the wire case and the details of the figure are as follows. This is for illustrative purposes only. The limitation of this structure of the fork. The road distribution=Fig. is the oil of the circulating pump 1 of the variable pump with the cooling system of the present invention. The variable cooling system circulating pump i of the present invention comprises a ^, 10 and - internal spray gear pump 2, wherein the inner fitting gear 20 J uses the (4) 2 to cool the hydraulic oil. The hydraulic pressure of the present invention is said to be hydraulic hydraulic work, the hydraulic oil is sent to the oil phase via the oil pressure block 3, and the internal '(four) gear pump 2 () sends the hydraulic oil inside the oil tank 4 to the cold portion. 2 Cooling is performed, and the cooled hydraulic oil is sent to the inside of the tank 4. The cooler 2 is used to fully cool the internal pressure test oil of the fuel tank 4, and the hydraulic oil is cooled. * When the liquid raft inside the oil tank 4 is repeatedly operated by this cycle, the temperature of the hydraulic oil in the oil tank 4 is inevitably lowered. . Referring to Figure 4 and Figure 5, a perspective view and an exploded perspective view of the cycle fruit 1 of the variable chestnut cooling system of the present invention are shown. The variable pump attached cooling system circulation system 1 of the present invention includes a variable pump 1 () and a (four) combined gear | (9), wherein the two pumps 10, 20 are connected by a joint cover 30. The connection cover 30 has multiple functions. At the same time, it has the effect of closing behind the variable fruit 10 and connecting the inner spit gear pump 2 . Even the moss 2, the anchor 32, wherein the set of fixing holes 31 is fixed by a number of screws 33, and the connecting cover 30 is fixed to the variable pump 1〇. The variable pump 10 is provided with a drive connection shaft u that passes through the connection cover. The two ends of the connecting cover 30 are respectively provided with a communicating oil hole material and an inlet hole, and an external oil pipe (not shown) is provided in 200918755. The inner spray gear pump 20 includes a body 21, a driven gear 22 and a drive gear 23. The driving gear 23 is placed on the variable pump 10 to drive the connecting shaft 11, and the driven gear 22 is further placed on the driving gear 23. The variable pump 10 drives the connecting shaft 11 to drive the internal gear pump 20 to rotate the two gears 22, 23. The main body 21 simultaneously covers the two gears 22 and 23 and is coupled to the connecting cover 30. The main body 21 is provided with a plurality of through holes 211, and the plurality of fixing screws 212 are screwed through the through holes 211 to the fixing holes 32 of the connecting cover 30. One end of the body gear 21 of the internal gear pump 20 is provided with a pressure chamber 213, and a set of safety valves 40 are disposed in the pressure chamber 213 to selectively allow hydraulic oil to form a circuit between the internal gear pump 20 and the safety valve 40. The safety valve 40 includes a steel ball 41, a spring 42 and a spring retainer 43 which are sequentially loaded into the pressure chamber 213. The internal gear pump 20 is coupled to the variable displacement pump 10 through the connection cover 30 to allow the variable pump to be attached to the cooling system circulation pump 1 to be reduced in size, and it is possible to save space, and since the length of the internal gear pump 20 is shortened, the piping can be relatively neat. Even when the internal gear pump 20 is damaged or abnormal and needs to be repaired, the internal gear pump 20 can be directly disassembled and separated from the connecting cover 30 without disassembling the external connection of the oil outlet 34 and the oil inlet hole 35 of the connecting cover 30. Tubing, whether installed or disassembled, can be done quickly and easily. At the same time, the cooling pump of the present invention has the effect of avoiding damage of the internal gear pump 20 because of the design of the safety valve 40. The variable pump attached cooling system circulating pump of the present invention comprises a variable pump and an internal coupling gear pump, wherein the inner fitting gear pump is mounted on the variable 8 200918755 pump by the connecting cover to avoid internal engagement, the piping is neat and the installation and disassembly are easy. Advantages, the same use of the internal gear 5 gear pump mounted on the safety valve gear pump damage. As far as the above is concerned, the invention has the following advantages: The variable pump is connected to the cooling system, and the variable pump is combined with the inner part, and the transmission connection shaft and the connection cover are connected between the two to reach the space of Lang. the goal of. 2 jInvented "variable pump with cooling system circulating pump", because the connection cover is easy to disassemble and has the advantage of maintenance materials. The invention relates to a variable pump with a cooling system, wherein the _ toothed wheel pump is provided with a safety valve to avoid damage to the gear. The above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, so that the numerical value is changed or the equivalent element is replaced, or the equivalent of the scope of the patent application of the present invention. Changes and modifications should still be covered by the patents of the present invention. "
