Description

本发明涉及一种用于从容器(例如一个柔性容器)中排放流体并且防止污物通过它进入容器的阀组件。 The present invention relates to a discharge fluid from the container (e.g., a flexible container) and prevent contaminants from entering the container through the valve assembly which is. 阀组件包括一个细长的阀体,阀体上有一个从侧面封盖阀体外表面的弹性包皮。 The valve assembly includes an elongated body, the valve body has a closure on an outer surface of the elastic sheath from the side of the valve body. 流体流经过阀体进入阀体外表面与弹性包皮之间的空间。 Fluid flow through the valve body into the space between the outer surface of the elastic sheath. 接着,流体流朝内返回阀体并通过输出或排放通道流出阀体。 Next, the body fluid return flow inwardly through the output or discharge passage and the outflow valve.

在从一个容器(容器的使用寿命还要延续一段时间)中向外分配无菌流体时,很重要的一点是防止污染流在分配操作中或之后回流到容器中。 When dispensing a fluid from a sterile container (a container life to continue for some time) outward, it is important to prevent contamination of the flow back into the container during the dispensing operation or after. 源于阀组件和容器之外的污染物包括微生物,大气成分、湿气、灰尘等等。 Outside of the valve assembly from the container and contaminants including microorganisms, atmospheric composition, moisture, dust, and the like. 如果无菌流体被污染,就会使它的质量、效力、甚至安全性受到影响。 If the sterile fluid is contaminated, it will be the quality, effectiveness, or even safety is affected.

如果一个无菌流体容器使用一次后在一个较长时间内不再使用,流入容器的污染问题一般不存在。 If a sterile fluid container after a single use in a long period of time is no longer used, contamination into the container is generally not present. 在Frick的美国专利2,715,980中公开的一种公知的液体处置容器中,阀机构包括一个有穿过阀体的中央孔和从中央孔延伸到其外表面的若干支孔的阀体。 In one known liquid disposal container of Frick U.S. Patent No. 2,715,980 disclosed, the valve mechanism comprising a valve body through the valve body central bore and a plurality of branch bore extending from the central hole to the outer surface . 一个可膨胀的套,例如橡胶类材料的套,包住阀体的外表面阻止流体从支孔流出。 An inflatable sleeve, such as sleeve of rubber-like material, encase the outer surface of the valve body to prevent fluid flow out from the support hole. 当要分配流体时,流体流过中央孔,然后通过支孔使套膨胀,流体就可从套的一端流出。 When the fluid to be dispensed, the fluid flows through the central bore, then through the branch aperture so that the expansion sleeve, the fluid can flow out from one end of the sleeve. 在这一流动中,污染物可能流入套的膨胀端,并接着通过支孔和中央孔,回流到容器。 In this flow, the contaminants may flow into the expansion end of the sleeve, and then through the branch hole and the central hole, back to the container. 不能有效地阻止污染流进入容器。 Can not effectively prevent contamination of the flow into the container.

另一种配有弹性管或套的阀公开在Kulle的美国专利4、346、704中。 Another feature of the elastic tube or sleeve of the valve disclosed in U.S. Patent No. 4,346,704 Kulle. 一种母溶液被通过中央管或通道分配到把流体传送到弹性套或管内表面的支孔。 A master solution was through a central tube or channel assigned to the fluid to support an elastomeric sleeve or inner bore surface of the tube. 当流体受到压力时,使弹性管位移,允许从流体支管孔向外流到套端。 When the fluid under pressure, so that the displacement of the elastic tube, to allow fluid to flow from the sleeve end branching outwardly hole. Kulle的装置最初是为一次性使用设计的,例如分配麻醉剂。 Kulle apparatus originally designed for one-time use, for example, dispensing anesthetic. 由于一次性使用,因此不存在污染物回流到容器的问题。 Since disposable contaminants back to the container so there is no problem. Kulle的装置的意图是高速低压传送麻醉剂以便能精确地分配之。 Kulle device intended low-pressure high-speed transfer of anesthetic in order to allocate accurately.

因此,本发明的主要任务是提供一种既能容易地分配液体又能防止任何污染物通过它回流到装有剩余液体的容器中的容器用阀组件。 Therefore, the main object of the invention is to provide a liquid dispensing both easily through it can prevent any contamination back to the vessel containing the remaining liquid in the container with a valve assembly.

按照本发明,阀组件包括一个轴向细长的阀体,它有沿长度方向隔开的一个进口端,一个出口端。 According to the present invention, the valve assembly includes an axially elongated body, which has an inlet end spaced in the longitudinal direction, an outlet end. 阀体有一个外壳面,其上套有一个弹性包皮,从侧面封住和向内压贴在外表面上。 The valve body has a housing surface on which an elastic sleeve foreskin, and inwardly from the side seal pressed against the outer surface. 一个输入通道从进口端沿细长方向延伸一段距离。 An input channel extending from the inlet end a distance along the elongated direction. 一个或多个孔或支通道从输入通道相对于细长方向径向向外延伸到阀体的外表面。 One or more holes or passages branched from the input channel with respect to the elongate direction extending radially outwardly to the outer surface of the body. 在朝向阀体出口端的方向上,一个或多个孔或支通道从外表面基本径向向内地向沿细长方向延伸的输出通道延伸。 In the direction toward the outlet end of the valve body, the one or more holes or branched passage extending substantially radially from the outer surface to the interior output channel extending along the elongate direction. 输出通道的另一端位于阀体的出口端。 The other end of the output channels at the outlet end of the valve body.

当阀组件不使用时,弹性包皮紧包在阀体外表面上,阻止任何通过输出通道回到容器的回流。 When the valve assembly is not used, the elastic foreskin tight valve body outer surface to prevent any back into the container through the output channel reflux. 如果把压力作用在容器上迫使流体进入输入通道,流体从输入通道流进向外通到弹性包皮的孔中。 If pressure is applied to force fluid into the container on the input channels, the input channel from the fluid flow into the elastic sheath outwardly through the aperture. 流体的压力使弹性包皮向外径向张开,使阀体外表面和包皮之间的流体流到与输出通道连接的孔中。 The elastic pressure of the fluid radially outwardly flared sheath, the pores outside the body and the fluid flow channel between the surface and the output connected foreskin. 作用在流体上的压力和弹性包皮的反作用力迫使流体流出输出通道。 Fluid pressure acting on the reaction force and the elastic force fluid out of the foreskin output channel. 一旦流体流入与输出通道相连的孔,弹性包皮就恢复原状,紧紧地包住阀体并且阻止任何从与输出通道相连的孔进入阀体和包皮之间的空间的流体流动。 Once the fluid inflow hole connected to the output channels, the elastic restitution to the foreskin tightly encloses the valve body and prevent any flow of fluid into the space between the valve body and the foreskin from the hole connected to the output channel. 因此,能防止向容器的回流,确保污染物不进入容器而影响流体的质量、效力或菌性。 Thus, the container can be prevented to reflux, to ensure that contaminants do not enter the container and affect the quality of the fluid, or bacterial efficacy.

在一个优选实施例中,阀体在从容器流出的方向上是细长的。 In a preferred embodiment, the valve body is elongated in a direction flowing out from the container. 其一端,阀体有一个沿细长方向延伸并基本位于阀体中心的输入通道。 One end thereof, a valve body extending along the elongate direction of the valve body and substantially at the center of the input channels. 在大多数应用中,只有一个输出通道,而按照被分配的流体的特性,可以有多个输入通道。 In most applications, only one output channel, and in accordance with the characteristics of the fluid being dispensed, there may be a plurality of input channels.

在输入通道的阀体的一端,即与从容器接受流体的那一端相对的一端,有一个或多个与阀体细长方向成角度径向向外延伸到阀体外表面的孔。 In the end of the input channel of the valve body, i.e. the end opposite that end receive fluid from the vessel, one or more elongated valve body extending radially outwardly at an angle to the outer surface of the bore of the valve body. 虽然可以只用一个孔,但最好有多个孔按一定角度间隔分布,以便使向外流到弹性包皮内充胀包皮的流体均匀公布。 Although only one hole can be used, but preferably a plurality of angularly spaced holes, so that a uniform flow of fluid out of the inflatable elastic foreskin circumcision released.

在细长方向上与那些把流体传送到弹性包皮内的孔相隔开的位置上,还有另外一些孔,(通常它们的数量相同),用于使液体向内流到沿阀体细长方向延伸的输出通道并且流出阀体上向外离开容器的那一端。 In the elongated direction of the fluid to the position of those holes within the elastomeric sheath spaced apart, there are other holes (usually the same number of them), for the liquid to flow inwardly along the elongated body extending in a direction that output channel and the outflow end of the valve body outwardly away from the container. 换言之,离开孔的输出通道的一端形成阀体的排放端。 In other words, one end of the output channels away from the aperture formed in the discharge end of the valve body.

为了方便地制造阀体和提高流体流过阀体的效率,这些通道和孔的截面最好是完整的。 In order to facilitate manufacture of the valve body and improving the efficiency of fluid flow through the valve body, the cross section of these channels and apertures preferably are intact. 它们的截面可以是圆形或是椭圆形的。 Their cross section can be circular or elliptical.

根据包皮的弹性特性和要分配的流体流过阀体时的压力,可以在弹性包皮外面配一个刚性圆筒形零件,以限制包皮从阀体外表面向外位移的程度。 The elastic properties of the sheath to be dispensed and the pressure fluid flows through the valve, can be equipped with a rigid cylindrical element outside the elastic foreskin, the foreskin from the valve body to limit the extent of the outer surface of the outer displacement.

阀组件可用于多种容器,最适用于一种可压缩的柔性容器,如塑料袋、一个可折迭的打褶的塑料容器,一个炉风箱形容器等等。 The valve assembly can be used in a variety of containers, most suitable for a compressible flexible container, such as a plastic bag, a foldable plastic container pleated, a bellows-shaped furnaces and the like. 一个波纹管式容器公开于Rauh等的美国专利3,506,163,和Berger等的美国专利4,526,296。 U.S. Patent a bellows-type container is disclosed in U.S. Patent No. 3,506,163 and the like Rauh, and 4,526,296 to Berger et al. 这些分配容器与本发明明显相关处仅在于能对流体施加压力程度,这种压力使流体通过阀体充胀弹性包皮以使流体通过阀体到达出口端。 The dispensing container of the present invention can be significantly correlated only in the degree of pressure applied to the fluid, the pressure of the fluid through the valve body to the inflatable elastomeric sheath fluid through the valve body to the outlet end.

本阀组件可用于分配各种粘度的物质,包括液体、洗剂、胶滞体、粉末、气体等等。 This material dispensing valve assembly may be used in a variety of viscosities, including liquids, lotions, gel stagnation, powders, gases and the like. 分配容器可贮存和提供多种产品,如食品、药制剂、化装品、工业化学品、显影液、粘接剂、颜料等等。 Storage and dispensing container may provide a variety of products, such as food, drug preparations, cosmetics, industrial chemicals, developer, adhesive agents, pigments and the like.

本发明的一个显著特点是在弹性包皮和阀体或与阀体连接的部件之间有密封。 A significant feature of the invention is a sealing sheath and the valve body between the elastic member and the valve or connected to. 需要密封以保证从输入通道到通往阀体外表面和弹性包皮之间的液体流进输出通道的输出孔以实现流体的分配。 Need to be sealed to ensure that the liquid output aperture between the valve body and the outer surface of the elastomeric sheath from flowing into the input channel to output channel leading to effect dispensing of the fluid. 如果包皮的一端或两端是自由的,被分配的液体就会流失,并且污染物会进入孔和通道并最终进入容器。 If one or both ends of the foreskin is free, liquid is dispensed will be lost, and the contaminants will enter the pores and channels and ultimately into the container. 包皮的端部可用多种方式密封,如:用O形环、粘接剂、或用热固接或化学固接把套固定在阀体上,或与之连接的部件上。 End sealing foreskin variety of ways, such as: the upper O-ring, an adhesive, or bonding with a thermosetting or chemically fixed to the body member is fixed to the sleeve, or attached thereto. 包皮两端与阀体密封接合,通到包皮和阀体外表面之间的流体流只能通过输出孔和输出通道流出。 Sealing engagement with the valve body at both ends of the foreskin, the foreskin pass between the outer surface of the body and the only fluid flow out through the output aperture and the output channel. 因此,在分配操作中不会有流体损失。 Thus, during the dispensing operation will not have fluid loss. 此外,包皮的弹性特性也确保在通向包皮内表面的孔口上提供一种封闭,从而阻止污染物流通过与输入通道相连的孔和输入通道进入容器。 In addition, the elastic properties of the sheath also ensures that on the surface of the aperture leading to the inner sheath to provide a closed, preventing contamination from entering the container through the aperture and the stream input channel connected to an input channel.

多种材料可用于制造阀体和弹性包皮,这些材料与所分配的流体和对流体的除菌方法是相容的。 Variety of materials can be used to manufacture the valve body and the elastomeric sheath, these materials with the sterilization method of dispensing fluid and fluid are compatible. 如果使用高热除菌法,所选择的材料必须在除菌的温度范围内和除菌所需的时间期间内保持其完整性。 It maintains its integrity during the heat sterilization method if used, the material chosen must be sterilized and the time required for sterilization in the temperature range. 可以用其他方法除菌,如辐照、乙烯氧化物等。 It can be sterilized by other methods, such as radiation, ethylene oxide.

因为本发明的阀组件能防止任何污染流进入分配容器,所以无须添加防腐剂,使用防腐剂提高成本,影响产品效果,或有有害的副作用。 Because the valve assembly of the present invention can prevent any contamination of the flow into the dispensing container, there is no need to add preservatives, preservatives increase costs and affect product performance, or have harmful side effects.

在本发明的改进中,已注意到诸如微生物这样的污染物进入分配容器将在一个较短时间内发展成很大的群体。 In a development of the invention, it has been noted that contaminants such as microbes into the dispensing container in a short period develop into large groups. 对本发明进行了试验并已确定,本阀组件可防止任何这种污染流进入容器,因此被分配的流体在第一次分配后可以贮存较长时间而不会产生由于污染物进入容器而产生的任何有害影响。 The present invention has been tested and has been determined, the valve assembly prevents any contamination of such flow into the container, thus dispensing the first fluid in the dispensing storage for prolonged periods and can not generated contaminants from entering the container produced any harmful effects.

在一种典型的实施例中,可折迭的容器用聚烯烃制成,阀体用聚四氟乙烯制成,其外径为0.5英寸,弹性包皮用合成橡胶制成,其肖氏(Shore)硬度为50,内径为0.375英寸,外径为0.405英寸,弹性包皮外可围绕一钢性包皮,其内径为0.530英寸,当弹性包皮套在阀体上时就被撑开以确保所需的与阀体外表面的紧密接触,以便在不使用时阀组件阻止污染流。 In one exemplary embodiment, a collapsible container made of a polyolefin, the valve body is made of polytetrafluoroethylene, an outer diameter of 0.5 inches, the elastic sheath is made of synthetic rubber having a Shore A (Shore ) hardness of 50, an inner diameter of 0.375 inches, an outer diameter of 0.405 inches and an outer elastomeric sheath may surround a steel sheath, an inner diameter of 0.530 inches, the elastic bag when the leather was stretched when the valve body to ensure the required close contact with the outer surface of the body so that the valve assembly when not in use to prevent contamination stream. 还可以用天然橡胶和古搭波胶(gutta-percha)制造。 It may also take the ancient and natural rubber gum wave (gutta-percha) manufacturing.

图1中,显示了波纹管式柔性容器10和装在容器一端的阀组件12,阀组件12的构造使得当容器10被压缩时,其中的液体可以分出。 In FIG 1, a bellows-type flexible container 10 and a valve assembly mounted on the end of the vessel 12, the valve assembly 12 is configured such that when the container 10 is compressed, wherein the liquid may be separated.

图2显示了阀组件12的一个实施例,它包括一个在进口端16和出口端18之间延伸的细长的阀体14。 Figure 2 shows an embodiment of a valve assembly 12 which includes a valve body at the inlet end of an elongated extending between 1816 and an outlet end 14. 当阀体14被设置在分配容器上,进口端16与容器内部相通。 When the valve body 14 is provided on the dispensing container, the inner container inlet end 16 in communication.

输入通道20从阀体14的进口端16延伸一段长度。 Input channel 20 extends a length from the inlet end 16 of the valve body 14. 如图2所示,进口通道延伸长度大约为阀体的三分之一。 2, the inlet passageway extending a length of about one third of the valve body. 输入通道20的与进口端16相反端分成四个单独的口22,它们等角度地排列并且延伸到阀体14的外表面14a。 Input channels and the inlet end 16 opposite end 20 is divided into four separate ports 22 which are arranged equiangularly and extending to the outer surface 14a of the valve body 14. 口24间隔于阀体出口端18,它们等角度间隔地从外表面14a向内延伸并终止于输出通道26的内端。 Opening 24 spaced from the outlet end of the valve element 18, which extend equiangularly spaced inwardly from the outer surface 14a and terminating at the inner end 26 of the output channel. 输出通道26与输入通道20轴向对准,这两个通道在阀体的纵向互相分隔开。 Output channel 26 is aligned with the axial direction of the input channels 20, two passages spaced apart from each other in the longitudinal direction of the valve body.

弹性包皮28包围外表面14a并且基本上紧紧包住外表面。 Flexible sheath 28 surrounds the outer surface 14a and an outer surface substantially tightly wrap. 如图2所示,弹性包皮从阀体的进口端16附近延伸到出口端18附近,包皮28的每一端沿阀体长度向设置都被封在阀体的外表面14a上。 2, the elastic sheath from the inlet end of the valve body 16 extends to near the vicinity of the outlet end 18, 28 of each end of the sheath along the length of the valve body to be sealed are provided on the outer surface 14a of the valve body. 如图3a、3b和3d所示,当包皮28被放在阀体上时被拉紧,以至紧紧包住阀体,从而形成口22、24的通到阀体14外表面的开孔孔封闭物。 FIG 3a, 3b and 3d, when the sheath 28 is placed on the valve body is tightened, as well as tightly wrap the valve body, thereby forming a mouth opening into the through holes 22, 24 of the outer surface of the valve element 14 closure.

如图2所示,包皮被座于阀体14外表面上的槽32中的O形环件30固定在阀体14的外表面上。 The valve body 30 fixed to the outer surface 14 as shown, sheath 14 is the outer surface of the seat body 2 to the O-ring 32 in a groove. 用于密封包皮相对两端的方式可依材料类型和被分配的流体的特性而改变。 A sealing manner to follow the foreskin opposite ends of the material types and properties of the fluid to be dispensed is changed. 除O形环件30外,还可用热或化学固接方法或使用粘接剂来密封住包皮。 In addition to the O-ring outer member 30, may be fixed by thermal or chemical method or using an adhesive to seal the foreskin.

如果图1中的容器10受到挤压或在其长度方向上受到压缩,其中容纳的物质就会先通过输入通道20进入阀体14,然后通过阀组件12流出。 If the container 10 in FIG. 1 is squeezed or compressed in the longitudinal direction thereof, the substance contained therein will enter the first valve element 14 through the input passage 20, and then flows through the valve assembly 12. 当流体流出输入通道20,就进入四个孔22之中的一个孔并且径向向外流到阀体外表面14a。 When the fluid flows out of the input channel 20, enters a hole in the four holes 22 and flows outwardly radially outer surface of the valve element 14a. 流体的压力迫使包皮28向外膨胀,使流体在阀体外表面14a和弹性包皮内表面之间流动,直到到达另一组使流体径向向内流动的孔24中的一个。 Pressure of the fluid forces the sheath 28 to expand outwardly, so that fluid flow between the outer surface of the inner surface 14a of the valve body and the elastic sheath until it reaches the other group to make a hole in the fluid flow 24 radially inwardly. 从孔24来的流体通过输出通道从阀组件排出。 Fluid from the hole 24 is discharged from the valve assembly via the output channel.

当阀组件12中没有流体通过时,弹性包皮28就成为阀体14外表面上孔22、24的封闭物。 When the valve assembly 12 does not flow through the resilient sheath 28 of the valve body becomes the outer surface of the hole 14 of the closure 22, 24. 结果,防止脏物从阀组件倒流入容器。 As a result, to prevent dirt from flowing backward into the valve assembly from the container. 当流体使包皮28膨胀时,流体就能阻止脏物进入容器。 When sheath fluid 28 so inflated, fluid can prevent dirt from entering the container. 一旦流体到达孔24,弹性包皮就会收缩并且封住阀体14外表面14a上的孔24,因而防止流体经过输出通道26向容器回流。 Once the fluid reaches the hole 24, the elastic sheath will shrink and seal the hole 24 on outer surface 14 of the valve body 14a, thereby preventing fluid passage through the output 26 to a reflux.

图4中,阀组件的结构与图2的相似,然而,在弹性包皮稍外一点,包有一个细长的刚性圆筒件34。 In FIG. 4, a similar structure to the valve assembly of FIG. 2, however, slightly resilient outer sheath that package has an elongated rigid cylindrical member 34. 圆筒件34约束了包皮28的径向向外膨胀运动。 Sheath 34 constrains the cylindrical member 28 expands radially outward movement. 假如包皮的膨胀有失去控制的倾向,则圆筒件34能限制其向外运动。 If the foreskin is a tendency of losing control of the expansion, the cylindrical member 34 to limit their outward movement. 圆筒件34只在特定的场合才需要,它并不是本阀体组件的必不可少的元件。 The cylindrical member 34 is needed only in special circumstances, it is not an essential element of the present valve assembly.

图5和图6显示了本发明的另一实施例。 Figures 5 and 6 show another embodiment of the present invention. 阀组件112有一个阀体114,它有一个进口端116和一个出口端118。 The valve assembly 112 includes a valve body 114, which has an inlet end 116 and outlet end 118 a. 阀体114在进口一出口方向上是细长的。 An outlet valve body 114 in the direction of the inlet is elongated.

阀体有一个输入通道120,它从进口端116延伸的长度大约等于阀体两端间长度的1/4。 The valve body has an input channel 120, which is approximately equal to the length from the inlet end of the valve body 116 extending between both ends of 1/4 of the length. 与图2、3和4的实施例不同,从输入通道120的进口端116只有一个孔122向内延伸到阀体的外表面114a。 Unlike the embodiments of Figures 2, 3 and 4, only one hole 122 extending inwardly from the inlet end 116 of the input channel 120 to the outer surface of the body 114a. 在阀体上径向相对一侧,另一个孔124从外表面径向延伸到输出通道126的内端。 On the diametrically opposite side of the valve body, the other hole 124 extends radially from the outer surface to the inner end 126 of the output channel. 阀体外表面上的孔122,124的开口在细长方向上是隔开的。 Openings 122, 124 in the valve body outer surface spaced apart from the elongated direction. 这种独特的布置可从防止在弹性包皮128和阀体114的外表面114a之间产生流动沟通。 This unique arrangement can generate a flow communication between the resilient sheath 128 and an outer surface 114a of the valve body 114 is prevented from. 因此,在孔122中产生的流体流在外表面114a和包皮128之间绕着阀体流进孔124。 Therefore, the fluid generated in the hole 122 flows around the outer surface 114a and covers the valve body orifice 124 between the inlet 128 flows.

如图5中所示,弹性包皮的两相对端被O形环130封死在阀体114的外表面114a上。 As shown, the two opposite ends of the resilient sheath 130 is sealed by O-rings on the outer surface 114a of the valve body 114. 5.

图6中,孔122介于进口端和出口端之间。 In FIG. 6, the hole 122 is between inlet and outlet ends. 此外,弹性包皮128紧包在阀体114的外表114a上,封住孔122、124。 Further, the elastic sheath 128 tight on the body of the outer 114a 114, 122, 124 to seal the hole. 阀组件112的工作方式与带包皮28的阀组件12的工作方式基本相同,只有当流体被从容器压入输入通道120以便通过和绕过阀体进入输出通道126时,弹性包皮128才向外扩张。 The valve assembly 112 works with the valve assembly 28 with wrapper 12 is substantially the same mode of operation, only when fluid is forced into the input channel from the container into the valve body 120 so as to bypass output channel 126 and through the resilient sheath 128 outwardly until expansion.

一个弹性包皮228在进口端216附近到出口端218附近之间从侧面包住阀体外表面,盖住了阀体外表面上的孔222、224。 A resilient sheath 228 near the inlet end to the outlet end 216 between a side 218 close to enclose the outer surface of the body, covering the outer surface of the bore 222 of the valve body. 和前述各实施例一样,弹性包皮228的两端被O形环230封在阀体214的外表面上。 And as the foregoing embodiments, both ends of the elastic sheath 228 is an O-ring 230 on the outer surface 214 of the valve body. O形环卧入槽232中。 O-ring groove 232 into the horizontal. 如前所述,也可用其他方式固定包皮的端部,以使被通过阀组件分配的流体不绕过通向输出通道226的孔224旁路。 As described above, the end portion can also be otherwise secured foreskin so that the fluid to be dispensed through the valve assembly does not bypass the bypass hole 224 leading to an output channel 226.

从图8可看出,各孔径向相对。 As can be seen from FIG. 8, relative to the respective aperture. 另外的孔224与图中所示的孔相隔90°。 Further bore hole shown in FIG. 224 spaced 90 °.
