摘要： Exemplary two chamber foam pumps, refill units and dispensers utilizing the same are disclosed herein. An exemplary refill unit includes an inverted container having a neck located at the bottom of the container and a foam pump secured neck. The foam pump includes a first air pump chamber, a liquid pump chamber and a second air pump chamber. In addition, the pump includes a piston. The piston has a hollow central portion. A first air inlet aperture is located through a wall of the piston between the first air pump chamber and the hollow central portion. A liquid inlet aperture is located below the first air inlet aperture and between the liquid pump chamber and the hollow central portion. A second air inlet aperture is located through the wall the piston located below the liquid inlet aperture and between the second air pump chamber and the hollow central portion.

摘要： An automatic oil pump includes a drive chamber, having a reciprocal driving device, and an oil chamber, having a sucking device, located on two sides of a main body. The reciprocal driving device has a piston unit having a valve chamber at its center and a balance valve and is pushed by a spring. The drive chamber has grooves on its inside wall. The piston unit has two channels, allowing air to flow into the valve chamber past two sides of the piston unit. On the piston unit is a driving rod. The driving rod penetrates into the main body and reaches into the oil chamber. A hermetic cover and a movable piston are attached to an end of the driving rod. On the wall of the piston are pluralities of through holes. The reciprocal driving device drives the piston in the oil chamber to move reciprocally, so oil is sucked into and out of the oil chamber continuously. Thereby, oil sucking speed and volume are upgraded to save time and labor, and oil pumping efficiency is enhanced.
摘要翻译：自动油泵包括具有往复驱动装置的驱动室和具有位于主体两侧的吸入装置的油室。往复驱动装置具有活塞单元，在其中心具有阀室，并具有平衡阀并被弹簧推动。驱动室在其内壁上具有凹槽。活塞单元有两个通道，允许空气通过活塞单元的两侧流入阀室。在活塞单元上是一个驱动杆。驱动杆穿入主体并进入油室。密封盖和活动活塞安装在驱动杆的一端。在活塞的壁上有多个通孔。往复驱动装置驱动油室中的活塞往复运动，因此油被连续地吸入和排出油室。从而提高吸油速度和体积，节约时间和人力，提高抽油效率。

摘要： A compressed air pump comprising a compressed air piston motor (11) having a cylinder housing (12) and a low pressure piston (22) moveable between first and second end wall parts (13, 14) and a hydraulic piston pump (15) in the second end wall part (14). One side of the low pressure piston and the first end wall part together define a working chamber (21) and the other side of the piston (22) abuts and drives the hydraulic piston (24). A pilot piston (25), which is controlled by the low pressure piston (22) controls the supply of compressed air to the working chamber (21). A spring powers the return stroke of the low pressure piston and the hydraulic piston. The pilot piston (25) is housed in a pilot cylinder (35) incorporated in the first end wall part (13) and is mounted for movement between a first position and a second position. In the first position compressed air can be passed from an inlet (17) in the end wall part to the working chamber. In the second position the supply of compressed air is interrupted and an outlet opening (31) located between the working chamber (21) and an outlet (32) is opened so that return air can be evacuated. The pilot piston (25) has mounted therein a control piston (26) which is connected to the low pressure piston (22) and which controls the pilot piston to cause it to move from the first to the second position by opening a compressed air connection (41) to the pilot piston's working chamber (36).
