| Number | Title | Issue Date |
| 8011906 | Piston pump A piston pump includes a pump mechanism for changing a volume of a pump chamber to move a piston in a housing, and a feed mechanism that has a feed ring attached to a circular groove portion of the piston to be slaved with a movement of the piston. The feed mechanis... | 09/06/2011 |
| 7328748 | Thermal actuated plunger A downhole plunger for a gas/oil well comprises a valve to regulate fluid flow past the plunger and a thermal actuator to control the valve. The thermal actuator of the disclosed device enables the valve to open and close aperatures without relying on the physical i... | 02/12/2008 |
| 7314080 | Slidable sleeve plunger An improved plunger lift mechanism comprises an internal hollow body having bypass orifices that, when exposed, allow fluid to pass through during plunger descent in a downhole tube to the bottom of a production well. A slidable sleeve slides along the hollow body t... | 01/01/2008 |
| 7290602 | Internal shock absorber bypass plunger A bypass plunger having one or more internal shock absorbing elements and a variety of bypass orifice options is disclosed. ... | 11/06/2007 |
| 6945762 | Mechanically actuated gas separator for downhole pump A reciprocating downhole pump has a gas separator located at its bottom end. The separator forms a chamber that is expanded and contracted when the pump is reciprocated. Expansion and contraction of the chamber occurs by either the plunger reciprocating in the chamb... | 09/20/2005 |
| 6655927 | Radial piston pump with piston arrangement for controlling inlet/exit flow The radial piston pump possesses a pump housing in which a plurality of cylinder bores are provided having pump pistons placed therein which can be driven by a cam. Further, an arrangement is provided in each pump piston (3) wherein the inlet or the outle... | 12/02/2003 |
| 6648615 | Inflator A dual-direction inflator has a tube and a cover mounted on the tube. A rod extends through the cover and is inserted in the tube. A piston is received in the tube and mounted on an end of the rod. The piston has an air-in chamber and an air-out chamber d... | 11/18/2003 |
| 6626650 | Cyclically operated fluid displacement machine A displacement machine (10) comprises a housing (11), a reciprocating member (12) reciprocable linearly along an axis of reciprocation (13) in the housing (11) and defining with the housing (11) first (14) and second (15) variable volume chambers. A fluid... | 09/30/2003 |
| 6280162 | Radial piston pump A pump includes a pump housing with a bore, an inlet and an outlet, a piston movable in the bore, and an inlet valve and an outlet valve which are formed by a cup seal. The piston has a portion of a large diameter and a portion of a small diameter, each o... | 08/28/2001 |
| 6065947 | Two-stroke operable pump A pump includes a main body, a piston slidably received in the main body, and a hose having a first end attached to an end of the main body and a second end attached to the piston. A handle is attached to a piston rod, which, in turn, is attached to the p... | 05/23/2000 |
| 5921759 | Liquid metering piston pump and valves capable of being cleaned and sterilized without disassembly An inverted, displacer type piston pump for metering and dispensing liquids in which the cylinder is located beneath the piston and reciprocated via an actuator below the cylinder, and where the piston is held fixed. The liquid ingress and egress to and f... | 07/13/1999 |
| 5577896 | Pump An object of the present invention is to provide a pump which suppresses a decrease in the volumetric efficiency of the pump to a great extent even in case that the kinematic viscosity of a fluid is high with a compact structure of the pump itself. The pr... | 11/26/1996 |
| 5489197 | Bidirectionally pumping air pump An improved pump structure including a shaft tube, a pivot tube, a piston element, a push and pull element and a handle element.
