摘要： The invention describes a device for producing pulse-type highpressure liquid jets created by the impact of a piston on the liquid contained in a chamber having a hole for the outflow of the liquid. For this purpose the piston is accelerated in the cylinder by compressed gas and, after producing an impact returns to the initial position compressing the gas by feeding the liquid under pressure into said cylinder.

摘要： The invention describes a device for building-up fluid pressure pulses comprising a cylinder with a piston which divides the cylinder cavity into a high-pressure chamber and low-pressure chamber of which the first one has a hole and is filled with fluid while the second one communicates with a vessel containing compressed gas which accelerates the piston and the latter strikes the fluid contained in the first chamber so that said fluid is discharged under pressure through a hole in the chamber. The piston is of a differential design and its step of a larger diameter is located at the side of the first chamber while the step of a smaller diameter is located at the side of the second chamber, the cylinder between the steps being divided by a partition which, together with the piston steps, forms two hydraulic chambers. One of these chambers, located at the side of the step of a smaller diameter is in constant communication with the pressure line while the second one, located at the side of the step of a larger diameter is put periodically in communication with the first hydraulic chamber and simultaneously with the pressure line, and also with the drain line.
