摘要： A pump unit (la) comprising a cavity (6a) defined by an immobile part (17), a reciprocating part (16), and a top element (18) sealing the cavity to define a chamber. The top element is fixedly attached to a scrolling piston wall (5a), slidably disposed within the cavity to move perpendicularly relative the chamber, dividing it in two sealed subchambers, the chamber following the reciprocating parts component of the piston wall, along the immobile part. Each subchamber has inlets and outlets on the immobile part, that are alternately exposed and covered as the reciprocating part and the piston wall moves.

摘要： During a pressurization stroke of a high-pressure pump, a cylinder inner wall and a plunger receive a fuel pressure from the pressurization chamber. Meanwhile, an upper housing does not receive the fuel pressure from the pressurization chamber, so that its thickness can be made thin. A cylinder is comprised of a bottom portion, a cylindrical portion and a large-diameter cylindrical portion. When inserting the large-diameter cylindrical portion into a large engaging hole, the bottom portion and the cylindrical portion are not brought into contact with a lower housing. A high liquid-tightness between the bottom portion, the cylindrical portion and a small engaging hole can be ensured.

摘要： A pump, which generally includes a pump housing and a pump piston. The pump housing defines a central longitudinal bore, a transverse bore communicating with the central bore for conveying a liquid through the pump housing, a liquid reservoir communicating with the central bore and the transverse bore for retaining an amount of the liquid conveyed through the transverse bore and a pressure relief slot extending from the transverse bore to the liquid reservoir. The pump piston is axially and rotatably slidable within the central longitudinal bore for pumping the liquid through the transverse bore.

摘要： A fluid infusion device includes a fluid pump mechanism having a rotor and a stator. The rotor includes an optically detectable feature, a reference surface, and a cam element rising from the reference surface. The stator includes a cam element having a stator cam surface. The cam elements cooperate to axially displace the rotor as a function of angular position of the rotor, wherein the detectable feature rotates and axially translates as a function of angular position of the rotor. A biasing element provides force to urge the rotor cam element toward the stator cam element and toward the reference surface. A drive motor actuates the rotor to pump medication fluid from a fluid cartridge module to a body, via a subcutaneous conduit. An optical detection circuit interrogates the detectable feature during operation of the fluid pump mechanism to determine an operating condition of the fluid pump mechanism.

摘要： A well pump assembly has a barrel, a standing valve at an upper end of a standing valve chamber, and a plunger. A travelling valve admits well fluid into the barrel during a fill stroke. The travelling valve closes during a power stroke so that the plunger pushes well fluid from the barrel into the standing valve chamber. A gas release port extends from the standing valve chamber to the exterior of the pump assembly. A check valve in the gas release port has an outward flow blocking position for blocking liquid well fluid in the standing valve chamber from exiting through the gas release port while the plunger is in the power stroke. The check valve has a gas release position that enables gas present in the standing valve chamber to flow out the gas release port while the plunger is in the power stroke.

摘要： A vibratory cavitation pump is provided that includes a working cylinder having an fluid inlet and a fluid outlet, a rod extending into the cylinder, a piston fixed to the rod, a plate fixed to the rod and spaced from the piston, an activator slidably mounted to the rod between the piston and the plate and an oscillating pumping mechanism operably connected to the rod to move the rod with respect to the working cylinder. The sliding activator creates cavitation in the fluid being pumped to increase the ease of pumping the fluid, such as high viscosity fluids. The pump can also include an external cylinder disposed around the working cylinder to impart rotational motion to the incoming fluid, thereby enhancing the cavitation created in the fluid by the pump, rendering the fluid easy to displace.
