Abstract

The pulse generator has a cylinder with an operating pressure inlet (10), an operating pressure chamber (8) and a discharge opening (6) for mounting a valve rod (4) with a valve rod end (3) and a valve head (7). The cylinder is connected in a quiescent state and has a pre-tensioning pressure valve (1) and a pre-tensioning pressure chamber (2). The vale rod, the valve rod end and the valve head form a valve unit, which is displaceably supported in the generator and connects the operating pressure chamber with the pre-tensioning pressure chamber.
