Problems solved by technology

But this natural cooling is not always sufficient in exhaust systems with high thermal loads
This causes premature aging and corrosion of temperature-sensitive parts, especially piston rods, guide sleeves and diaphragms
this is unsatisfactory

Embodiment Construction

[0023] The drawing shows a thermal pulse gas silencer in a sectional view, in which only a section of the housing wall 0 is shown. An exhaust valve is assembled in the opening of the housing wall 0 through an assembly 15. This exhaust valve has a pressure nozzle 1 with a diaphragm 10, a spring 2, a piston 7 and a piston rod 3, in which a pressure connection pipe 4 is integrated. A closing member 5 in the form of a valve disc is fitted on the free end of the piston rod 3. The closing member 5 opens or closes the cross section of the air duct 9 integrated into the silencer.

[0024] Once the exhaust gas enters the pipe 9, the high pressure generated therein is transmitted to the pressure side of the diaphragm or piston 7 through the pressure connecting pipe 4 integrated into the piston rod 3. The diaphragm is open to the spring 2 and atmospheric external pressure, and the external pressure acts on the low pressure side of the piston 7 through the opening 6 in the pressure nozzle 1. ...

Abstract

A muffler with variable acoustic properties. A pressure cell with a diaphragm, a spring, a piston, a piston rod, a closing element on the piston rod, and a pressure connection line are integrated into a housing. The diaphragm is thermally insulated against the piston rod. Another layer of thermal insulation is provided between the closing element and the pressure cell.

Description

Technical field [0001] The present invention relates to a muffler with variable acoustic characteristics for pulsed gas. It at least includes a housing in which a pipe and an exhaust valve with a pressure nozzle are integrated. The nozzle has a diaphragm, a spring, The piston, the piston rod, the closing part on the piston rod and the pressure connecting pipe one, and a guide sleeve for the piston rod; the closing part more or less closes one of the pipes. Background technique [0002] From DE 195 03 322 C, a muffler with variable attenuation characteristics for pulsed gas is known. It includes a housing, an air duct leading to the housing, a pipe integrated therein, a diaphragm, a spring, The high-pressure nozzle of the piston rod and the pressure joint, in which the low-pressure side of the diaphragm is loaded by ambient pressure and spring, a pressure pipe that conducts gas pressure to the high-pressure side of the diaphragm, and a closing component for opening and closing the...
