摘要： A plunger pump including an airtight bellows surrounding a portion of a drive shaft to protect the drive shaft and associated seals and/or bearings from harmful fluids that are being pumped. No counter-pressure fluid exists inside the bellows, other than air, and the bellows is sufficiently rigid to withstand the pressure of the pumped fluid without collapsing. The interior of the bellows is in fluid communication with the atmosphere, negating the need for a reservoir to accommodate varying quantities of counter-pressure fluid as the pump operates.

摘要： Apparatus and methods of their use are described for engaging a pumping cartridge with a pump drive. In certain embodiments, the cartridge, comprising a cylinder and a movable piston assembly, is initially assembled or subsequently positioned so that the distance between the attachment point on the piston assembly for coupling to a drive assembly, and a reference point on the cylinder, is greater than the maximal distance that will be encountered during normal oscillation of the piston during use. The cartridge, in certain embodiments may be pressed into a drive assembly having means for immobilizing the cartridge and means for coupling the piston assembly to the driveshaft. In certain embodiments, when the cartridge is fully inserted into the drive assembly, the piston is pressed into the cylinder sufficiently to establish a selected distance so that the piston shaft is in the proper position to engage with a coupling mechanism carried on the driveshaft.

摘要： A pump system for delivering cryogenic liquids is proposed that is suitable, for example, for refueling motor vehicles with H2. It consists of a container for receiving the cryogenic liquid, in which at least one pump is arranged that is designed as a reciprocating pump with connecting rod actuation and spring recover. Pump cylinder (10) of the reciprocating pump is divided by means of plunger (24, 37) into two chambers (a and b) that are arranged on the pressure side or the induction side. By exerting tensile forces on connecting rod (29), in the pressure stroke the cryogenic liquid that is located in the container is initially trapped in chamber (b). When connecting rod (29) is returned to its starting position by return spring (23), the liquid that is trapped in chamber (b) is then hurled without pressure into chamber (a). In the subsequent pressure stroke, the liquid is finally released via a gap (d) to a pressure housing and from there to the consumer by exerting tensile forces on connecting rod (29).

摘要： Pumping cartridges useful for medical and surgical pumping and infusion procedures are disclosed. Methods for manufacturing and utilizing such pumping cartridges and methods for pumping or infusing liquids for delivery to the body of a patient or a surgical or medical instrument for performing a medical treatment are also described. The invention includes, in one aspect, a series of pumping cartridges comprising cylinders and pistons constructed and arranged for sliding or reciprocating motion within the cylinders. The pistons and/or cylinders can comprise a sealing component including a circumferential, flared sealing flange and can be configured to enable the pumping cartridge to generate high liquid pumping pressures, for example above 1,000 psig. Many of the pumping cartridges disclosed can be relatively easily manufactured at a low cost per unit and can be configured to be detachable from a pump drive unit and disposable after a single use. Various compact flow path configurations are provided in the several pumping cartridge embodiments described, including a Y-shaped configuration, a T-shaped configuration, and an axial configuration. Some pumping cartridges disclosed include pistons including or at least partially forming a valve and/or pistons that are relatively movable with respect to a piston rod to which they are connected. Valve including a valve seat and a movable sealing element able to create a seal capable of withstanding differences in fluid pressures thereacross of at least about 1,000 psi, and in some cases up to in excess of 10,000 psi, without substantial fluid leakage therethrough are disclosed. In some of the disclosed valves, the movable sealing element is concave in shape, and can be curved, to create a mechanical advantage for improved sealing performance. Methods for manufacturing axially-configured pumping cartridges from thin-walled tubing are also disclosed, as well as a series of methods for pumping or infusing a liquid for delivery to the body of a patient or a surgical or medical instrument for performing a medical treatment using the above-mentioned pumping cartridges and devices.

摘要： A rod-driven, downhole pump is disclosed, the pump including a traveling barrel contained within a pump housing, a central pump rod extending axially within the barrel, a valve ball located at the lower end of the pump rod, a valve seat near the barrel lower end, the pump rod including a rod shoulder for engaging the upper end of the barrel, the barrel containing annular passageways for the flow of fluid through the barrel, the pump rod reciprocable within the barrel, and the barrel reciprocable within the pump housing. The downward stroke of the pump rod causes the rod shoulder to engage the barrel upper end and concurrently displaces the valve ball below the valve seat, thereby allowing environmental fluid to flow through the barrel annular passageways. On the up stroke of the pump rod, the valve ball engages the valve seat and pushes the pump barrel upward within the pump housing. The sealing of the valve ball on the valve seat and the upward movement of the barrel displace columnar fluid upwardly.
