A pulse metering valve has a cylindrical body with axial channel and inner threading at one end, separation membrane, two inlet pipe connections placed on generatrix surface of the body and connected to each other through axial channel, outlet pipe connection by one end is tightly fixed in the channel of the end of the other end of the body. The metering valve is mechanically rigidly connected to rotary spring, piezoelectric ceramic element is by one end mechanically rigidly connected to pusher and by the other end is connected with possibility of kinematical motion to pressing nut and connected to source of electric power. To resist high dynamical overloads the end of outlet pipe connection has a gasket with ring-like edge with triangular cross section and conical depression that is connected to the channel of outlet pipe connection. |
