DEVICE FOR PRODUCING HIGH PRESSURE IN DISPERSED FLUID MEDIUM Russian patent published in 2002 - IPC

FIELD: hydraulic engineering. SUBSTANCE: device contains hollow plunger mounted for movement inside cylinder and valve member mounted for axial movement with respect to the hollow plunger and guided by the hollow plunger. The valve member is placed close to the plunger end inside or in front of it. The device is used in mechanical atomizer of high pressure. The atomizer has a housing consisting of two parts. The housing receives pump housing with a nozzle, locking gear, spring housing with a spring, depressed tank for storing the fluid, and mechanical counter built into the spring housing. The valve operates without any additional force, rapidly shut down in response to fluid flow, and strongly isolates from high pressure. The atomizer is safe, convenient in operation and ecological compatibility. The fluid flow rate is measured very accurate. The valve operates under the friction on the walls of the cylinder. Device also has space of high pressure placed inside the cylinder in front of the plunger, stopper- rod device placed in the hollow plunger which stops valve member motion. The valve member is sealed at its inlet. EFFECT: enhanced efficiency. 26 cl, 18 dwg
