    • PURPOSE:To reduce the current of a motor and permit the efficient operation of the pump by a method wherein a piston ring for a larger piston is expanded forcibly upon the operation of the smaller piston, in order to reduce sliding torque. CONSTITUTION:A plunger 75 is attracted to a core 74a and a movable lever 61 is rotated counterclockwisely about a pin 63. At this time, the second piston ring 12 is separated from the second piston 9b and is expanded toward the outside thereof, therefore, a clearance is produced between the second piston ring 12 and the second piston 9b and the clearance is brought into non-sealed condition. Accordingly, driving torque for the second pump is not necessary substantially upon operating as a compressor, therefore, the driving torque may be reduced.
    • 目的:为了减少电机的电流,并通过一种方法使泵的高效运行,其中在较小活塞的操作时,用于较大活塞的活塞环被强制地膨胀,以便减小滑动扭矩。 构成:柱塞75被吸引到芯部74a,可动杆61围绕销63逆时针旋转。此时,第二活塞环12与第二活塞9b分离并朝向其外侧扩张,因此, 在第二活塞环12和第二活塞9b之间产生间隙,并且间隙处于非密封状态。 因此,在作为压缩机进行动作时,基本上不需要第二泵的驱动转矩,因此,可以降低驱动转矩。

    • A hand pump for inflating rafts or similar inflatables has a first piston with a relatively low pumping volume which is capable of pumping relatively small volumes of air into a raft as the raft becomes full and is approaching its maximum pressure, and a second piston with a larger pumping volume that can pump larger volumes of air into a raft when it is empty or only partially filled. Both pistons are operated with a single plunger. When the plunger is rotated in a first direction to a first position a locking mechanism allows it to operate only the first piston, and when the plunger is rotated in a second direction to a second position the locking mechanism allows it to operate only the second piston.
    • 用于充气筏或类似的充气器的手动泵具有具有相对低的泵送体积的第一活塞,当第一活塞具有相对较小的泵送体积时,其能够在筏充满并且接近其最大压力时将相对较小体积的空气泵送到筏中,并且具有 较大的泵送体积,当空气或仅部分填充时,可将较大体积的空气泵入筏。 两个活塞都用一个柱塞进行操作。 当柱塞沿第一方向旋转到第一位置时,锁定机构允许其仅操作第一活塞,并且当柱塞沿第二方向旋转到第二位置时,锁定机构允许其仅操作第二活塞 。

    • A piston pump which is intended particularly for use in a slip-controlled hydraulic vehicle brake system. To increase a pumping volume of the piston pump at low pumping pressure, the piston pump includes a body embodied preferably as an annular body which is attached axially displaceably to the piston. The body increases a cross- sectional area of the piston and is axially acted upon by a spring element. At low pressure, the piston pump pumps with the entire cross-sectional area of the piston and the body while conversely at a higher pumping pressure, the body is held back counter to the force of the spring element and does not move together with the piston so that then the piston pumps only with its own cross-sectional area. The piston pump of the invention has the advantage of improved pressure buildup dynamics when the pumping pressure at the onset of pumping is low.

    • A piston type pump having a cylinder sleeve mounted in a pump cartridge assembly for insertion and removal with the cartridge assembly from a bore in the pump casing. The cartridge assembly has a head portion extending across the outer end of the casing bore and a sleeve portion integral with the head portion, and the cylinder sleeve is pressed into the sleeve portion to provide a wear liner for the pump piston. Outlet passage means and outlet check valve means are provided in the head portion of the cartridge to control discharge of fluid from the pump, and inlet passage means and inlet check valve means are provided in the pump piston to control intake of fluid.
