Definitions

  • the invention belongs to daily necessities, and is mainly installed on a bottle cap, and the water agent or the emulsion-like cleaning beauty product in the bottle is pumped out by hand pressing. Background technique
  • the existing bath or lotion pumps are named according to their use or liquid form, and their structures are identical. They are all reciprocating piston pumps.
  • the bath pump has been connected to the cap, and the tube and nozzle are configured to supply the market. It is a general-purpose product that has been widely used for many years, yet it is inefficient, regardless of material utilization or strength.
  • the 3 ml bath pump purchased from the workshop was re-measured.
  • the average height of the bathing pump cylinder was 86 mm, and the connecting section of the guiding tube was 16 mm.
  • the balancing hole of the bathing pump was on the cylinder wall, 12 legs away from the cylinder port.
  • the piston In order to avoid the piston pumping out, the piston must be installed below the cylinder leg 12, so the upper part of the cylinder block is the effective part of the cylinder block, the pump cylinder section should be 70 mm; and the piston height is 10 mm, according to which the piston can be calculated
  • the piston stroke is 14.28%; the piston stroke is 15 mm, and the pump cylinder height is only 21. 4%. It can be seen that the stroke ratio for pumping is very low.
  • the piston needs strict sealing on the inner wall of the pump, which inevitably brings static friction and dynamic friction resistance. Because the pump body is long, in order to facilitate the mold release, a large draft slope is required, which causes the piston to move downward when the piston moves downward. Increase to the maximum at the end of the stroke.
  • the bead check valve is often used, because of its simple structure and reliable use, but the fluid resistance is very large. If a larger diameter bead is used, the annulus is limited by the diameter of the tube; if a smaller diameter bead is used, the diameter of the orifice that forms a seal with the bead is smaller, which also increases the fluid resistance.
  • the resistance of the fluid is proportional to the square of the flow velocity, and the flow velocity is inversely proportional to the square of the pipe diameter. Therefore, the resistance is proportional to the fourth power of the pipe diameter, so the small diameter and small annular gap have a great influence on the resistance. It can be seen that the existing bath pump has the bead check valve installed at the smallest diameter of the pressure rod outlet, which is a big drawback.
  • the maximum diameter of the plunger is at the coupling end with the piston and is therefore the preferred position for the outlet check valve.
  • the inlet check valve should also not be installed in the inlet pipe.
  • the resistance of the inlet check valve is too large, resulting in an increase in the negative pressure in the pump body. Therefore, a larger elastic force is required to overcome the fluid resistance, and a spring with a larger wire diameter is required. Therefore, the inlet check valve should be installed in the open position of the bottom of the tank, and the larger diameter check valve should be used.

Description

弹性构件泵 技术领域
本发明属于日常生活用品, 主要安装于瓶盖上, 通过用手按压将 包装瓶内的水剂或乳液状的清洁美容用品泵出。 背景技术
现有的沐浴泵或乳液泵, 是按其用途或液体形态来命名的, 其结 构完全相同, 都属往复式活塞泵。
沐浴泵已联接在瓶盖里, 再加引管和喷头配置好供应市场, 是通 用的产品, 广泛使用多年, 然而它却是低效率的, 不管从材料利用率 或力量的使用。
由坊间购买的 3毫升沐浴泵, 经重新测量,沐浴泵的缸体平均总 高度 86毫米, 引管的联接段 16毫米; 沐浴泵的平衡小孔在缸壁上, 离缸口 12腿处, 为避免活塞抽空, 活塞必须安装于缸口 12腿以下, 因此缸体上部的联接段是缸体的有效部份, 泵缸段应为 70毫米; 而 活塞高 10毫米, 据此可算出活塞约占泵缸段高的 14. 28%; 活塞行程 是 15毫米, 以泵缸段高度计只为 21. 4%, 可见用于泵液的行程比例 很低。
按压沐浴泵还需要较大的力, 经测定, 按压至行程最底端将液体 排出, 随按压速度不同, 用力 2. 5-2. 8千克, 不打液时按压需 2. 3千 克力, 单压弹簧至 20毫米处要 1. 3-1. 5千克力。 耗如此大力却只排 3毫升液至瓶高 200-300毫米高度, 能量效率太低了。
活塞对泵体内壁需要严格密封, 就必然带来静摩擦和动摩擦阻 力, 由于泵体较长, 为了便于出模, 就需要较大的拔模斜率, 这就造 成活塞往下运动时阻力进一部增大, 至行程末端达到最大值。
考察沐浴泵的单向阀, 较多使用珠子单向阀, 因具有结构简单、 使用可靠的优点, 但流体阻力很大。 若用较大直径的珠, 受管径的限 制, 环隙就小; 若用较小直径的珠, 与珠子形成密封的管口直径就更 小, 也使流体阻力加大。 流体的阻力与流速的平方成正比, 而流速又 与管径的平方成反比,因此阻力与管径的 4次方成正比,因而小管径、 小环隙对阻力的影响非常大。可见现有的沐浴泵将珠子单向阀安装于 压杆出口直径最小处, 是很大的弊端。
压杆直径最大处是在与活塞的联接端,因此是出口单向阀的优选 位置。
进口单向阀也不应安装于进口管内,特别是进口单向阀的阻力太 大, 造成泵体内负压增大, 就需要更大的弹力来克服流体阻力,就需 要较大线径的弹簧, 因此, 进口单向阀应优先安装于缸底开阔处, 并 取用较大直径的单向阀。 发明内容
为了克服现有的沐浴活塞泵的不足,本发明人提出了二项中国发 明专利, 分别是申请号为 201210153053. 8 的〈〈往复式弹性膜泵〉〉和 申请号为 201210458655. 4的〈〈按压式弹性囊泵〉〉, 其能提高泵的容 _ 积效率, 节省原材料, 使用时较省力。
为避免繁复, 在下文的引用中, 〈〈往复式弹性膜泵〉〉称专利 1 ; 〈〈按压式弹性囊泵〉〉称专利 2。
二项专利实际上都使用了现有的活塞沐浴泵的外部构件,包括瓶 盖、泵体、泵盖、压杆、喷嘴及密封圈, 构件的联接关系也大体相同; 弹性膜和弹性囊都因压下而使沐浴泵排液, 利用其反弹而吸液; 弹性 膜和弹性囊同样替换了活塞和复位弹簧的功能, 克服了因活塞的 "动 态密封 "所带来的摩擦。 因此若将弹性膜和弹性囊视为弹性构件, 则 二种沐浴泵结构的同一性便大于其差异性。弹性囊可视为较厚的弹性 膜, 差别只在弹性膜是利用了薄弹性体的拉伸及其反弹特性,弹性囊 是利用对厚弹性体的压迫、 曲折弹性及其反弹特性。实际上对弹性囊 进一歩施力也能实现拉伸变形。
弹性构件在拉伸变形或压迫变形时,与泵体内壁的关联可按设计 的需要选择接触或不接触泵体内壁。 在外部构件上二项专利都作了相同的优化:
1.将平衡小口移至瓶盖上, 弹性构件就能安装于泵体口上, 大致 能减少 10mm的泵体高度。 由于泵口直径较大, 因此可用较大直径的 弹性构件, 原泵体的内径是 15mm, 而泵体口部内径为 19mm, 若仍然 为 3ml的排液量, 行程就只需 9. 4mm, 合共约减少 19mm的高度。
2. 出口单向阀改为活页式单向阀, 安装于压杆直径最大处即在 弹性构件的联接端。 3. 进口单向阀改为活页式单向阀, 安装于缸底开阔处, 并取用 较大的直径。而活页式单向阀具有几乎全开全闭的属性, 具有最小的 阻力特性。
4.弹性构件是弹性膜或弹性囊大多不需要弹簧,或者使用锥形弹 簧, 综合能减少 39mm的高度, 即节省近 50%的缸体材料。
5.将瓶盖和泵盖或者瓶盖和泵体一次注塑而成,以减少模具费用 和生产、 装配成本。
二项专利采用了同样的物理原理及相同的、优化的外部构件, 类 似的联接及密封方式, 因此为方便在结构上的描述, 就将弹性膜和弹 性囊统称弹性构件。
本发明通过以下技术方案来实现:弹性构件泵包括:引管、泵体、 进口单向阀、 弹性构件(弹性膜或弹性囊) 、 压杆、 出口单向阀、 瓶 盖、 泵盖、 喷头、 密封圈组成。 瓶盖有圆孔, 缸体外有圆盘, 可从瓶 盖下端插入, 泵体口伸出瓶盖成为结合部, 弹性构件置于缸体内,其 口部外延置于泵体口结合部, 泵盖压迫泵口并将弹性构件固定和密 封,同时固定瓶盖和泵体的联接; 缸体圆盘在瓶盖内与其盖底圆环重 合, 缸体与瓶盖的环隙内塞入密封圈; 引管插入泵体底部管口, 泵体 内开阔处设置进口单向阀; 弹性构件在泵体内, 压杆的一端口和弹性 构件相嵌合, 形成密封,压杆空腔内有出口单向阀, 压杆的另一端联 接喷头。
泵体圆盘和瓶盖上分别有平衡小孔,两平衡小孔相对; 在正对两 平衡小孔中心的密封圈的两侧加刀口, 就形成单向活页, 瓶子的内压 降低时, 瓶外的空气经平衡小孔推开单向活页进入瓶内; 对瓶内的液 体却能保持关闭。 为便于安装, 三者还应有定位标识。
使用时用手按压喷头, 带动压杆向下运动, 就压迫弹性构件在 泵体内发生弹性变形, 压到末端, 弹性构件的下端接近泵体的底部, 在此过程中弹性构件下的泵体内容积变小, 泵体内压增大, 进、 出口 单向阀在压力的作用下自动启闭, 液体经弹性构件出口、 压杆、 从喷 嘴排出。
放开对喷头的按压, 弹性构件将在泵体内发生回弹, 使泵体内压 降低, 进、 出口单向阀在压力的作用下自动启闭而将液体吸入。
上述由泵盖、瓶盖及泵体三个部件构成的外部结构是沿用了常规 活塞泵的结构,实际上幷无必要, 泵盖和瓶盖或泵体和瓶盖都可合并 注塑为一体。
再进一歩, 可以将弹性构件泵装入喷头内, 因一般喷头的截面积 与瓶盖相当。
安装于喷头内的弹性构件泵包括:泵体、进口单向阀、弹性构件、 压杆、 出口单向阀、 泵盖、 喷嘴组成; 泵体和喷嘴一次注塑而成, 喷 嘴其入口管在泵体的底部, 喷嘴内安装出口单向阀; 泵体开口有结合 部, 弹性构件的口部外延置于泵体口结合部, 泵盖固定于缸口并稳定 压杆; 压杆的一端和弹性构件的圆口相嵌合, 形成密封, 压杆空腔内 有进口单向阀; 压杆另一端联接瓶盖接口, 再联接引管, 引管位于瓶 盖内并伸入瓶中。
弹性构件安装于泵体内, 而泵体置于瓶盖里, 泵的外观和功能相 _ 同。 但弹性构件是弹性囊时,还具有外置的功能, 即可外置瓶盖上也 可外置于喷头上; 弹性囊还可以包含喷嘴及包含瓶盖的构造; 外置的 弹性囊还便于美化造型, 大凡能形成半空腔的外形都可利用, 因此有 更大的发挥空间。
综上所述的泵体都有结合部, 指的是泵体的某种结构, 用于实现 与弹性构件的联接和密封, 如泵体口部或泵体园盘, 其表面可以带齿 牙或凹坑或凸圈;弹性构件都有外缘,外缘指的也是某种结构,因应和 泵体结合部的密封、联接关系而设计的构造, 或者只是简单的园环或 者是带嵌合结构的园盘, 不一而足。
进一歩, 若把喷嘴的按压面延长并在喷嘴出口四周加上梳齿, 就 成了能泵液的梳子了, 用手按压梳头就能泵出液体于梳头的梳齿间。
如参照发明专利 200310111947. 1 《异位活塞泵和具有异位活塞 泵的染发梳 》 的结构作相同的改进, 就能用于该发明专利相同的染 发梳结构中。
工业上有薄膜泵, 但其原理不同, 是由电机或其他致动机构使隔 膜往复运动, 因此又叫隔膜泵。 隔膜泵的薄膜只为了隔绝作用, 避免 液体中的有害悬浮物或化学物对构件的侵蚀。
弹性构件是用弹性体材料制造, 随着新材料的不断涌现, 为可用 于食品卫生用品的 TPE、 TPV、 TPR、 TPU等弹性体材料提供了更多 的选择。通过对弹性构件的形状、厚度的设计或者和金属弹簧的配合, 便不难获得理想的弹性构件泵产品。
在弹性构件泵中使用的进、出口单向阀为活页式单向阀, 活页式 单向阀也用弹性体材料制成,由中间的活页、 外侧的定位及折位构成 一体的圆薄板状, 活页的直径较欲密封的管口大; 活页和定位之间有 环隙,折位成凹槽联接活页和定位, 折位凹槽的直线薄处提供了活页 的旋转轴,当活页上下有压力差时, 活页掀动以启闭管口, 用弹性体 材料制造的活页单向阀具有较佳的密封和回弹特性。
折位的截面形状、宽度及厚度可用于设计活页掀动时所需的最小 力度和最大开启角度,前者需考虑单向阀活页在液体中有浮力的影响 而后者需考虑太大的角度不再显著的降低阻力却可能造成活页的回 弹迟缓。
在使用中的折位,随着掀开角度的增大,需要的力矩也增大,但缸 内的负压在减少,因此活页实际的开启角度和掀动活页的力矩及形成 的负压、 流体的阻力等相关联。
出口单向阀与进口单向阀的结构相同。
需要考虑进口单向阀的活页在液体中也有浮力的影响,除外 还 要预计当瓶子倾倒时单向活页仍可抵御液柱高度,避免液体泄漏的可 能,就需设计成活页对管口、 对液柱的常闭状态, 因此出口阻力就会 加大, 但对于人手按压来说增加的力道有限。若在进口单向阀加大对 液柱的密封, 将使吸入阻力加大, 增加缸体内的负压, 所以对液柱的 密封宜用出口单向阀。
以下对弹性构件泵的结构作进一部的说明。
需要指出两项专利的的相同构件使用了不同的名称,如缸体和泵 体、 泵盖和缸口塞等, 实为一物; 还有部分构件的标注也有不同。 因专利 2弹性囊的实施例引用较多,为便于比较及避免歧意或误 判, 因此有关专利 1弹性膜的图例和标注都作了改变, 统一于专利 2 弹性囊的标注。
由泵盖、瓶盖及泵体三个部件构成的沐浴泵的外部结构, 实施例 不再引用。泵盖和瓶盖或泵体和瓶盖都已合并注塑为一体, 保留其原 名称只为方便描述与其他构件的空间位置及联接关系。 附图说明

泵体圆盘 3. 5和瓶盖 7的圆环上分别有平衡小孔 3. 4和 7. 6相对, 如图 la所示: 在正对两平衡小孔中心的密封圈 10的两侧加刀口, 就 形成单向活页 12. 1, 瓶子的内压降低时, 瓶外的空气经平衡小孔 7. 6 和 3. 4推开单向活页 12. 1进入瓶内, 对瓶内的液体却能保持关闭。
实施例二
如图 2所示, 弹性构件泵内置于瓶盖,弹性构件是弹性膜。 其包 括泵体 3、 弹性膜 4、 瓶盖 7、 压杆 8、 泵盖 9、 喷头 10、 密封圈 12 ; 瓶盖 7和泵盖 9注塑成一体, 泵体 3置于瓶盖 7内; 泵体 3有作为泵 的进口通道的进管口 3. 2, 进管口 3. 2内安装有进口单向阀 2 ; 泵体 _
3上部开口 3. 1为结合部, 弹性膜 4置于缸口内,弹性膜有外缘 4. 1 配合嵌塞入泵体的结合部 3. 1; 泵体圆盘 3. 5可从瓶盖 7下端嵌插, 使泵盖 9压迫弹性膜的外缘 4. 1和泵体的结合部 3. 1,并形成密封,同 时固定泵体 2和瓶盖 7的联接; 弹性膜 4中心有管口 4. 2, 管口 4. 2 上安装有出口单向阀 6,管口 4. 2密封联接压杆 8, 压杆 8底板外延 8. 2和弹性膜 4紧配合并和泵体 3的内壁相关联 (接触或不接触) , 压杆 8—端穿过泵盖 9的孔道 9. 2联接喷头 10, 为泵的出口通道; 孔道 9. 2起垂直引导压杆 8的作用。

比较图 2和图 1不难看出以上两种弹性构件泵的联接关系大多相 同, 只是弹性囊和弹性膜的密封面略有差异,弹性囊的外缘 4. 1和泵 体的结合部 3. 1密封,结合部 3. 1就是园盘 3. 5。
实际上泵体的结合部是能改变的,弹性膜也能用园盘 3. 5为结合 部,例如取消凸出于园盘 3. 5的 3. 1构造。
实际上,图 1和图 2弹性构件的外缘也可开刀口形成活页,那么 密封圈 12就可取消。
泵体 3也可和瓶盖 7注塑成一体,则泵体 3的园盘 3. 5和瓶盖环 隙联成一体,泵体园盘的平衡小孔 3. 4将和瓶盖 7的平衡小孔 7. 6合 二为一, 即瓶盖 7 的环隙上只有平衡小孔 7. 6和密封圈的单向活页 12. 1相对。
泵体 3和瓶盖 7注塑成一体, 其结合部还能有不同的变化, 泵体 还可带喷嘴, 如下例的方式。 实施例三
如图 3所示, 弹性构件泵其泵体外置于瓶盖 7上, 弹性构件为弹 性囊。泵体 3底部为瓶盖 7的一部分,即泵体 3与瓶盖 7注塑成一体, 泵体还带有喷嘴 5 ; 泵体 3的进管口 3. 2在瓶盖 7的中心, 其上安装 进口单向阀 2, 进管口 3. 2下端连接引管 1, 引管 1位于瓶盖 7内并 伸入瓶中, 为泵的进口通道; 出管口 3. 3内安装有出口单向阀 6, 喷 嘴 5和泵体 3的出管口 3. 3联成一体, 为泵的出口通道; 泵体 3上部 开口有结合部 3. 1, 弹性囊 4 (作为弹性构件) 置于泵体外, 其外缘 4. 1可配合嵌塞入泵体 3的结合部 3. 1, 并形成密封, 弹性囊 4成为 按压面。
瓶盖 7上有平衡小孔 7. 6, 环隙内有密封圈 12, 密封圈有单向活 页 12. 1和平衡小孔相对。
泵体和瓶盖也可分离, 如实施例四。 实施例四
如图 4所示, 弹性构件泵, 泵体 3带有喷嘴 5 ; 泵体 3侧壁 3. 3 有出管口 3. 3, 喷嘴 5和泵体 3的出管口 3. 3联成一体, 为泵的出口 通道, 出管口 3. 3内安装有出口单向阀 6; 泵体 3中心有进管口 3. 2 其上安装进口单向阀 2, 泵体的进管口 3. 2下端联接压杆 8, 压杆 8 另一端联接瓶盖接口 7. 3, 再联接引管 1, 引管 1位于瓶盖 7内并伸 入瓶中, 为泵的进口通道; 泵体 3上部开口有结合部 3. 1, 弹性囊 4 (作为弹性构件) 有外缘 4. 1可配合嵌塞入泵体 3的结合部 3. 1, 并 形成密封。 弹性囊 4成为按压面, 一经按压液体就能由喷嘴 5流出, 完全与喷头相同。
泵体 3带有喷嘴 5,与瓶盖 7之间用压杆 8联接,其与喷头无异, 故可视为弹性构件泵安装于喷头中, 喷头的外壳成了泵体。
弹性构件是弹性囊也可内置安装于喷头内, 如实施例五。 实施例五
如图 5所示, 弹性构件泵的弹性构件为弹性囊, 泵体 3带有喷嘴 5; 泵体 3侧壁有出管口 3. 3, 喷头的喷嘴 5和泵体 3的出管口 3. 3 联成一体, 为泵的出口通道, 出管口 3. 3内安装有出口单向阀 6; 弹 性构件中心有管口 4. 2, 其上安装进口单向阀 2, 管口 4. 2下端联接 压杆 8, 压杆 8另一端联接瓶盖接口 7. 3再联接引管 1, 引管 1位于 瓶盖 7内并伸入瓶中, 为泵的进口通道; 泵体 3开口有结合部 3. 1, 弹性囊 4 (作为弹性构件) 有外缘 4. 1可配合嵌塞入泵体 3的结合部 3. 1, 有泵盖 9压迫和固定并形成密封, 泵盖的孔道 9. 2起垂直引导 压杆 8的作用。

图 6未画出瓶盖、 瓶盖接口及引管, 可参阅图 4和图 5。
实施例四、 实施例五和实施例六,压杆 8和引管 1可合并为一只 压杆件, 压杆件穿过瓶盖接口 7. 3伸入瓶中。
以上实施例四至实施例六,瓶盖 7的环隙上有平衡小孔 7. 6和密 封圈 12的活页 12. 1相对 (结合图 la) 。 实施例七
如图 7所示, 弹性构件泵的弹性构件是弹性囊 4, 配置了瓶盖 47和喷嘴 45, 三者一次注塑而成; 还包括引管 1、 喷嘴 45、 瓶盖 47、 密封圈 12 ; 其泵体 3中心有进管口 3. 2, 其上安装进口单向阀 2, 进管口 3. 2下端联接引管 1, 引管 1位于瓶盖 47内并伸入瓶中, 为泵的进口通道; 泵体 3上部园盘 3. 5为结合部, 弹性囊 4 (作为 弹性构件) 外置泵体外, 泵体 3园盘 3. 5与弹性构件的瓶盖 47套 合密封;喷嘴 45和泵体 3的空腔相通,喷嘴 5内安装出口单向阀 6, 喷嘴 45为泵的出口通道; 泵体 3的圆盘 3. 5和瓶盖 7的环隙上分 别有平衡小孔 3. 4和 7. 6, 两个平衡小孔和密封圈 12的单向活页 12. 1 (结合图 la所示) 相对。
弹性囊 4也是按压面。 实施例八
如图 8所示,金属弹簧 11套入弹性膜 4中,金属弹簧的外圈 11. 1 和弹性膜 4的外缘 4. 1必须和配合的结合部相适应。金属弹簧优选为 锥形弹簧, 令其从上到下相邻的每圈直径都大于其线径, 则压迫到底 时弹簧 11就成盘状, 其高度即为线径。
金属弹簧也可和弹性构件注塑成一体。显然以上各实施例都可按 需要作相应的配置。 实施例九
如图 9所示, 实施例一至七的进口单向阀、 出口单向阀优选采用 本实施例的活页式单向阀结构。活页式单向阀用弹性体材料制成。 由 中间的活页 21、 外侧的定位 22及折位 23构成一体的园薄板状, 定 位 22包含了定位构造园孔 22. 1; 活页 21的直径较欲密封的管口大; 活页 21和定位 22间有折位 23成凹槽联接, 折位凹槽的直线薄处提 _ 供了活页 21的旋转轴。折位 23的截面形状、宽度及厚度, 需设计成 活页对管口或对液柱的常闭状态。
不难看出单向阀的园环不是必需的,在狭小的管道里可取消园 环; 而用于定位的构造也不限于园孔, 或更进一歩可取消园孔, 改为 边上带插脚的定位构造, 从而为活页留下较大的空间。
以上各实施例有关单向阀和密封面的图示只为叙述其配合关系, 其细部的结构应该是工业设计的内容。
以上各实施例的瓶盖也未画出螺牙。
由以上各实施例中不难看到弹性构件的不同变化。当弹性构件与 压杆有联接关系时,弹性构件会因置入不同的单向阀而改变其作为进 口或出口的功能, 如实施例一和实施例二, 弹性构件 4的管口 4. 2为 出管口; 而实施例五和实施例六, 弹性构件 4的管口 4. 2为进管口。
弹性构件还可包含中间隔膜,泵体也包含相应的结合部, 有此结 构的弹性构件泵便能方便地一次按压, 同时排出两种液体。
瓶盖上的平衡小孔也可配置于瓶盖侧壁,小孔穿过瓶盖环隙与泵 体园盘的平衡小孔相通并与密封圈的单向活页相对,这有利于扩大瓶 盖的可使用的面积, 以便配置更大面积的弹性构件。
弹性构件采用弹性体材料制造,需要适应弹性构件对伸长、压縮、 曲折的弹性要求, 以及和泵体、 瓶盖的配合, 还决定于沐浴泵使用的 便利性及接受市场对美学的审视, 因此必须有更多的研究, 需要对其 进一歩的改进。特别是也不限制其他用途, 比如在梳子内的应用。 有 电机带动的弹性构件, 弹性体的回弹性能不很重要, 但对密封性及耐 疲劳性(耐用性)却有更高的要求, 如家用鱼缸使用的空气泵、 循环 水泵, 还有工业小型往复式活塞压縮机、 活塞式风泵等, 将活塞对缸 壁的动态密封改成弹性构件的密封,将大大减少摩擦损失,节约能耗。 大的压縮比及高温会对弹性构件的实施有一定的限制。
