摘要： The invention is a pump adaptable to pump mud and silt or other slurried material. The pump comprises two cylinders. While one is pumping, the other is filling with mud. Each cylinder has a piston (preferably floating) in it which separates the mud from the hydraulic fluid. The hydraulic fluid is oil or is essentially water containing soluble oils for lubrication. The hydraulic fluid is pumped out of one cylinder and into the other. This operation draws the floating piston away from one end of the first cylinder, thereby drawing in the mud under vacuum plus the differential barometric head. At the same time an equal volume of hydraulic fluid is pumped into the other cylinder, causing the piston therein to eject mud through a mud line. At the moment that one piston reaches one extreme of its stroke, the other one reaches the other extreme of its stroke. At this same moment, a switching mechanism changes the direction of flow of the hydraulic fluid between the two cylinders. Also, at this same moment, the positions of the two cylinders relative to a discharge line opening are shifted so that the cylinder which has just filled with mud becomes aligned with the mud line to shore and it begins its exhaust stroke. This fluid reversal and shifting will generally take place several times per minute. To change the relative positions of the cylinders and the mud line, the mud line may be shifted from one cylinder to the other, or the cylinders may be shifted while the mud line remains stationary.
摘要翻译：本发明是适用于泵送泥浆和淤泥或其它浆料的泵。泵包括两个气缸。当一个人在抽水时，另一个人正在灌满泥土。每个气缸在其中具有活塞（优选地是浮动的），其将泥浆与液压流体分离。液压油是油，或者基本上是含有用于润滑的可溶性油的水。液压油从一个气缸中泵出并进入另一个气缸。该操作将浮动活塞从第一气缸的一端拉出，从而在真空下吸入泥浆和差压气压头。同时将等体积的液压流体泵送到另一个气缸中，使其中的活塞通过泥线排出泥浆。在一个活塞达到其行程的一个极限的时刻，另一个活塞达到其行程的另一极限。在同一时刻，切换机构改变两个气缸之间的液压流体的流动方向。此外，在同一时刻，两个气缸相对于排出口开口的位置移动，使得刚刚填充泥浆的气缸与泥线对准，并开始其排气冲程。这种流体反转和移位通常会每分钟进行几次。为了改变气缸和泥浆线的相对位置，泥线可以从一个气缸移动到另一个气缸，或者当泥浆管路保持静止时，气缸可以移动。
