Abstract

本发明涉及用于内燃机的机械式冷却剂泵(10)。所述用于内燃机的机械式冷却剂泵(10)包括向包括出口阀(20)的出口通道(16)中泵送冷却剂的叶轮(18)。出口阀(20)包括可移动的扁平阀板(22),该阀板(22)穿过出口通道壁(26)中的通道切口(24)在出口通道(16)的横截面内可移动。

Description

机械式冷却剂泵
技术领域
本发明涉及用于内燃机的机械式冷却剂泵,其带有用于泵送冷却剂进入出口通道的叶轮,其中出口通道包括出口阀。
背景技术
机械式冷却剂泵是一种由燃式发动机驱动的冷却剂泵,例如通过使用驱动带驱动泵的驱动轮。只要燃式发动机是冷却的,就仅需要最小的冷却剂流。因此,采用设置有用于控制冷却剂循环流的出口阀的机械式冷却剂泵。只要燃式发动机是冷却的,出口阀就关闭,使润滑剂的循环最少化,从而使燃式发动机暖机时间减少。
通常,出口阀采用枢轴封盖(pivoting flap)的形式,由此枢轴封盖位于润滑剂出口通道中。枢轴封盖能够受到控制,以旋转封盖到开启或者关闭的位置,由此该位置确定了冷却剂循环流。这种枢轴封盖在润滑剂出口通道内的布置,即使在封盖开启位置也会限制冷却剂流,并引起流阻(flow resistance)。此外,这种枢轴封盖会由于磨损、变形、以及处于附着在封盖上的润滑剂中的和封盖的凹部中的颗粒而被卡住。
发明内容
本发明的一个目的是提供出口阀得到改善的机械式冷却剂泵。
本发明的目的通过具有以下特征的机械式冷却剂泵得以实现。
根据本发明的一方面,用于内燃机的机械式冷却剂泵包括向包括出口阀的出口通道中泵送冷却剂的叶轮。出口阀包括可移动的扁平阀板,该阀板穿过出口通道壁中的通道切口在出口通道的横截面内可移动。
出口通道中的可移动的扁平阀板能够实现对燃式发动机的冷却剂流进行控制,以便在冷起动阶段提供最优的冷却剂量。在燃式发动机的冷起动阶段中对冷却剂流的控制能使暖机更快,因此改善了燃式发动机的能量效率。阀板穿过出口通道壁中的通道切口在出口通道的横截面中的可移动性允许使用驱动器。由于板与板导引之间的滑动摩擦低,并且冷却剂作用于阀板的压力并不显著地影响使阀板移动进入开启或关闭位置所需的致动力,所以致动器具有相对低的致动力。因此,冷却剂流在冷却剂循环中不受限制。
根据本发明一优选实施例,阀板在开启位置时位于流体密封的阀板套中,并且阀板套从出口通道径向地延伸。流体密封的阀板套保持阀板始终处于润滑剂空间内,使通道切口无需密封。
优选是,阀板套形成为主泵体的独立部件。阀板套单独安装到主泵体,改善了阀板套的形式和材料的灵活性,使阀板套能够由不同于主泵体的材料制成。
或者,阀板套为主泵体的集成部件。这种结构允许更快且更有成本效率的生产。
主泵体优选设置有用于可移动的扁平阀板的通道切口。
根据本发明一优选实施例,主泵体在出口通道设置有用于可移动的扁平阀板的导向切口,阀板被导引在导向切口中。导向切口为阀板提供附加的支撑,以对抗持续冲击于未开启位置的阀板的冷却剂流的压力,并确保阀板在出口通道中的横向可移动性。
优选是,阀板由致动器驱动。
根据本发明一优选实施例,致动器直接连接到阀板套,从而无需齿轮或杠杆或者其它装置来转变致动器的运动为阀板的运动。
优选是,阀板由气动致动器驱动。阀板也可由其它致动器致动,如电致动器或恒温致动器等。气动能源可从燃式发动机的不同位置进行利用,以使气动致动器的使用简单且成本有效。
气动致动器优选设置有膜和垂直于膜的驱动杆,其中驱动杆直接连接到阀板,并且轴向地与阀板成一直线,这样就无需齿轮或杠杆等装置。
附图说明
以下是本发明实施例参考附图的详细说明,其中:
图1示出了机械式冷却剂泵的透视图,
图2示出了机械式冷却剂泵的纵向部分,
图3示出了图2的机械式冷却剂泵沿线III-III的截面,
图4示出了机械式冷却剂泵的仰视图。
具体实施方式
在图1中,示出了用于内燃机的机械式冷却剂泵10。该机械式冷却剂泵10包括主泵体11,由此,主泵体通过法兰12直接安装到发动机缸体上或者可具有盖板(未示出)。
主泵体11容纳可旋转的叶轮18,叶轮18沿轴向吸入冷却剂、并把冷却剂沿径向朝外泵入涡室(volute)15。叶轮18由燃式发动机通过使用驱动带(未示出)来驱动,驱动带驱动机械式冷却剂泵10的驱动轮38。冷却剂由于离心力从涡室15流入出口通道16,并穿过出口阀20到出口开口14。出口阀20位于出口通道16的终端。
出口阀20包括可移动的扁平阀板22,阀板22穿过出口通道壁26的通道切口(passing slit)24在出口通道16的横截面内可移动。阀板22位于流体密封的阀板套28中时处于开启位置,阀板套28从出口通道16在通道切口24处径向地延伸出来。可移动的阀板22由气动致动器32驱动,其中,阀板22被引导在导向切口30中,并且导向切口30设置在通道壁26中。
致动器32设置有位于膜壳35中的气动膜34和垂直于膜34的致动杆36,其中,致动杆36轴向地与阀板22成一直线。致动器32直接连接到阀板套28。在开启位置,阀板22完全位于阀板套28内,因此冷却剂流不受限制。只要燃式发动机是冷却的,出口阀20就可由气动致动器32完全地或部分地关闭。
图2示出了机械式冷却剂泵10的纵向截面。机械式冷却剂泵10包括主泵体11。在主泵体11的顶部,设置有阀板套28,其中,阀板套28从出口通道16沿径向并相对于机械式冷却剂泵10的法兰12垂直地延伸。
在图3中,示出了图2的机械式冷却剂泵10的截面III-III。可移动的阀板22由气动致动器32经由气动膜34和驱动杆36驱动。驱动杆36轴向地与阀板22成一直线,并且垂直于膜34。膜34由预紧弹簧37预紧,使出口阀20进入关闭位置。或者,预紧弹簧37可相反地配置成预紧出口阀20到开启位置,从而得到失效安全的结构。
