417481000 | Oscillating pumping member | 11 |
20090148320 | Fluidic Energy Transfer Devices - A fluid energy transfer device, including a chamber for receiving a fluid, at least a portion of the chamber comprising a movable portion relative to another portion of the chamber, the movable portion being adapted to change the volume of the chamber from a first volume to a second volume by movement of the movable portion. The device further includes an actuator attached to the movable portion, wherein the displacements of the movable portion can be larger than the displacement of the actuator. | 06-11-2009 |
20100196181 | Pump Device - A pump that enhances the flow of liquids in a system according to the movement of one or more generally planar oscillating members within a fluid flow chamber, as directed by rotation of a simple crank member. | 08-05-2010 |
20110038744 | SYSTEM FOR CONSTRUCTION OF PUMPS, COMPRESSORS AND ROTARY ENGINE COMPOSED OF TWO ROTORS WITH ONE, TWO OR MORE DISPLACER'S EACH, THAT MOVE THEMSELVES IN THE SAME DIRECTION AT SPEEDS THAT ARE VARYING AND ALTERNATIVLY OPPOSITE EACH OTHER - The new system is characterized by the fact that the displaced volume and the relative position of the intake, exhaust ports ( | 02-17-2011 |
20110081267 | PUMP - A fluid pump comprising a chamber which, in use, contains a fluid to be pumped, the chamber including a main cavity having a substantially cylindrical shape bounded by first and second end walls and a side wall and a secondary cavity extending radially outwards of the main cavity, one or more actuators which, in use, cause oscillatory motion of the first end wall in a direction substantially perpendicular to the plane of the first end wall, and whereby, in use, the axial oscillations of the end walls drive radial oscillations of the fluid pressure in the main cavity, and wherein the secondary cavity spaces the side wall from the first end wall such that the first end wall can move relative to the side wall when the actuator is activated. | 04-07-2011 |
20130017109 | FLUID COMPRESSOR OR PUMP APPARATUSAANM Flenche; GeorgeAACI Elizabeth DownsAACO AUAAGP Flenche; George Elizabeth Downs AU - The present invention relates to an apparatus which may be in the form of a pump or compressor and which can function to compress or accelerate a fluid such as air, gas, gaseous mixtures and/or liquid. In particular, the invention provides a mechanism in which fluid can be admitted and then discharged continuously from each of the radial compartments that make up the compressor chamber. | 01-17-2013 |
20130236343 | COMPRESSOR WITH LOW FRICTION SEALING - The invention relates to a compressor comprising a rotatable portion where the active volume is divided by transverse wings ( | 09-12-2013 |
20140234145 | ARRANGEMENT OF COMPONENTS OF A LINEAR COMPRESSOR - The present invention refers to the arrangement of components comprised in a linear compressor ( | 08-21-2014 |

20120063939 | HIGH PRESSURE PUMP INCLUDING HOLLOW STUD - A high-pressure fluid pump is operable to pressurize a fluid and includes a hollow stud including a first end, a second end, and a cylindrical space extending between the first end and the second end and a housing fixedly coupled to the first end of the hollow stud. A high pressure cylinder is disposed within the cylindrical space of the hollow stud. The high pressure cylinder includes a bore that extends from a first end to a second end of the high pressure cylinder. A seal head is engaged with the first end of the high pressure cylinder to define a seal therebetween and an end cap is coupled to the second end of the hollow stud and the seal head. The end cap is operable to apply a compressive force to the seal head to compress the seal head against the cylinder and to apply a tensile load to the hollow stud. A plunger is movable within the bore to pressurize the fluid in a space defined by the piston, the seal head, and the high pressure cylinder. | 03-15-2012 |
20120107161 | Pumping Device that is Operated Easily and Safely - A pumping device includes a barrel, a top cover mounted on the top of the barrel, a first switching valve mounted on the top cover, a base mounted on the bottom of the barrel, a second switching valve mounted on the base, a cylinder connected between the top cover and the base, a piston movably mounted in the cylinder, a plurality of check valves mounted on the piston, an operation unit connected with the piston, and a conduit connected between the barrel and the base. Thus, a user has to pull or push the first switching valve and the second switching valve simultaneously to extract or suck the fluid in the barrel so as to deflate or inflate the barrel so that the pumping device has a security process and is operated in a safer manner. | 05-03-2012 |
