Abstract

Thrust and suction pump belongs to a group of capacitative pumps and carries out the function of suction and thrust of fluids. It consists of a pump cylinder i.e. body of the pump (6) wherein, onto a carrying axle (10), is set an upper part of a piston (17) and an upper part of a piston (5) while at the suction part of the pump (1) is set an element (3) that prevents counter flow of fluids. On the upper part of the piston (17) there are openings (16), (13), (12) that are used so as to let the fluid through and provide its flowing away i.e. unloading of the upper part of the piston (17), while in the inside of it there are: an upper tight element (14) that closes i.e. opens openings (16) on the upper part of the piston (17). On the external surface of the upper part of the piston (17) there is a tight element (15). On the bottom part of the piston (5) there are openings (9) and (4) that are used to let the fluid through and enable its flowing away i.e. carry out unloading of the bottom part of the piston (5) while in the inside of the bottom part of the piston (5) there is the bottom tight element (8) that closes i.e. opens the openings (4) on the bottom part of the piston (5). On the external surface of the bottom part of the piston (5) there is a tight element (7). At the suction opening (1) there is an element (3) that prevents counter flow of the fluids through the suction opening (1), and thereon it has openings (2) that make the flow of fluids into the cylinder (6) easy.
