WAVE-POWERED INJECTOR AND METHOD TO INJECT FLUIDS WITH ITS HELP Russian patent published in 2016 - IPC F03B13/18 

FIELD: machine building.

SUBSTANCE: invention is related to injectors powered by wave energy. The injector comprises a submersible cylinder 102 fixed to the bottom of the water zone. The cylinder 102 is fitted by a hole 106. The cylinder 102 is affected by a submerged float 114. The submerged float 114 is made so that to hold the cylinder 102 vertically in the water. A surface float 126 is made so that it floats on the water surface in its operating condition in order to move up and down in the water in accordance with the wave movement and tidal movement. An elongated element 118 goes down from the float 126. The element 118 enters the hole 116 in a telescopic way to form a delivery chamber 148 inside the cylinder 102. The volume of the chamber 148 is changed along with the wave movement in delivering cycle in order to suck fluid into the chamber 148 while the element 118 goes up and discharge the fluid from the chamber 148 while the element 118 goes down. The length of the chamber 148 is changed depending on the tidal movement. The element 118 occupies the most of the cross-section area of the hole 116 at the section where the element 118 is drawn into the hole 116.

EFFECT: invention is aimed at design simplification.
