摘要： An apparatus for cooling-water extraction for a robot installation plate is characterized by an adjustable extraction volume. The extraction volume is achieved by a sufficiently large extraction cylinder which has a maximum extraction volume, wherein the extraction volume is adjusted by a mechanical stroke limit of a piston located in the extraction cylinder. In at least one embodiment, the mechanical stroke limit is realized by an adjustment screw that is on or in the extraction cylinder. The adjustment screw forms a stop that provides an end position limit or stroke limit of the piston.

摘要： A positive displacement pump for dispensing fluid includes a fluid body sub-assembly including a fluid body and a negating check valve. The negating check valve includes a negating body defining a dispensing opening. The fluid body and the negating body form a flow path for the fluid. The fluid is dispensed through the dispensing opening. The positive displacement pump is primed by allowing trapped air within the flow path to flow out of the dispensing opening. The negating check valve may be fully or partially attached to the fluid body. The trapped air within the flow path flows out of the dispensing opening when the negating check valve is partially attached to the fluid body.

摘要： An adhesive dispensing system includes a pump and at least one sensor positioned to sense movements of a component of the pump and produce signals based on the sensed movements. The dispensing system also includes a controller communicating with the at least one sensor to collect information regarding operational cycles of the pump based on the signals. As a result, one or more diagnostic processes are enabled at the controller during operation of the adhesive dispensing system. These diagnostic processes may include a leak rate test for the dispensing system, an overspeed detection test for the pump, and expected life cycle monitoring of the pump or other components.

摘要： A flow-through filling pump for receiving a liquid supply and discharging a predetermined amount of the liquid therefrom includes a housing defining a supply chamber and a discharge chamber and a reciprocating piston positioned in the housing intermediate the supply and discharge chambers. The piston is movable along an axial liquid flow path defined by the chamber, between a fill position and a discharge position. A drive assembly is operably connected to the piston to drive the piston between the fill and discharge positions. A seal member extends between the piston and the housing to isolate the supply and the discharge chambers and at least a portion of the piston from a portion of the housing at which the drive assembly operably connects to the piston. The pump includes a non-return type inlet valve mounted to the piston. The inlet valve has a biasedly mounted valve element, which is biased to the closed position. The inlet valve is moveable with the piston and the valve element is movable relative to the piston to permit and to terminate flow of liquid through the valve into the discharge chamber as the piston is moved between the fill and discharge positions.

摘要： A gas driven oscillator (10) comprising an engine (11) having a cylinder (12) and a pair of expansion chambers (13, 14) on either side of a floating piston (15) adapted to reciprocate within the cylinder (12). The piston (15) is mounted on a piston rod (16) extending through the cylinder (12) and into a compressor (17). Compressed air is delivered from a tank (20) to the engine (11) via a pair of valves (22, 23) mounted on an adjustment screw and slidably disposed on the piston rod (16). The spacing between the valves (22, 23) can be adjusted in order to vary the amplitude of the piston (15) within the cylinder (12). The piston rod (16) includes spaced slots (24, 25) which alternate align with passages inside the respective valves (22, 23) to deliver a pulse of compressed air to the respective chambers (13, 14) of the cylinder (12). Mercury is added to or discharged from a tank (42) which is rigidly secured to piston rod (16) to vary the inertia of the oscillator (10).

摘要： The invention is a method for producing reservoir fluids from an underground reservoir through the wellbore. The method includes the steps of intaking the gas phase from the wellbore into the wellbore-contained pump drive, powering the pump drive using the gas pressure of the gas phase in the wellbore, pumping the liquid phase from the wellbore towards the surface by a first pump and exhausting the gas phase from the pump drive towards the surface.

摘要： Pumping under the present invention includes movement of material, in a first embodiment fluid and in a second embodiment a piston assembly, between first and second positions including detection of said material at each position. Control circuitry and supporting mechanical and fluid coupling responsive to material position toggles the pump into alternate modes of operation driving the material toward each point. The pump arrangement has fewer moving parts than traditional pumps and enjoys higher reliability for its simplified design.

摘要： Pump units comprising a metering reciprocating pump with adjustable length of stroke are used in packing machines for filling of packing containers with a metered quantity of flowable contents, e.g. yogurt. Adjustments in the length of stroke in order to adapt the amount of filling goods to the volume of the packing container interferes with the breaking sequence at the extreme position of the piston and alters the time for each pumping stroke. These drawbacks are avoided by means of an arrangement which includes a movable braking device for the piston as well as a valve arrangement which is linked to the braking device and serves to adapt the speed of the piston to the length of stroke.
