Abstract: With reference to FIG. 3, the present invention provides a fluid injector (10) which functions as a positive displacement pump and comprises: a housing (12) in which a piston chamber is formed; a piston (11) which reciprocates in the piston chamber to define therewith a variable volume fluid pumping chamber; a one-way inlet valve (32) which allows flow of fluid into the pumping chamber from a fluid inlet; and a one-way outlet valve (25, 26, 27, 28, 29) which allows flow of fluid out of the pumping chamber to a fluid outlet (31).

The hollow spaces are sealed off relative to each other by a sealing ring which is arranged on the piston member. The piston member is secured in place by a cover member which is bolted to one end member associated with the second housing component. Similar bolt secure the end members associated with the second housing component together.

Abstract: An oscillating piston compressor characterized by a spherically contoured piston chamber in which a wedge-shaped disk-like piston is journaled for oscillating motion on an axle journaled in the housing and coinciding with the juncture of a pair of semi-circular sectors forming the piston.

Abstract: A pumping device whose functioning resembles the action of the natural four chambered heart is constructed as a total cardiac replacement unit. An internal electrical drive motor adapted to be powered by radio frequency induction across intact skin drives an eccentric rotary element which in turn causes oscillation of pivoted vanes whose movements cyclically compress a pair of blood compatible sacs which simulate the left ventricle and right ventricle of the natural heart by pumping blood through the aorta and pulmonary artery, respectively. As in the natural heart, stroke volume of each ventricle is independent of the other and is a function of right atrial and left atrial pressure and volume. Additional embodiments of the invention feature modified driving means for the pumping vanes.
