Actuator module

Abstract

The invention relates to an actuator module (1) with a hermetically sealed module housing (3), which extends longitudinally in an axial direction (RAX), with at least one piezo actuator (2) arranged in the module housing (3) and with electrical terminals (6a, 6b) at least for the piezo actuator (2), which terminals (6a, 6b) are fed through a module housing wall (3w), wherein a module housing interior space (3i) between the piezo actuator (2) and the module housing wall (3w) comprises a potting compound (4), which electrically insulates the module housing wall (3w) from the piezo actuator (2) and which is formed in a heat-conducting manner, in particular with a heat-conducting auxiliary substance, wherein the module housing wall (3w) of the module housing (3) has a bellows (10, 20, 30, 40) with a wave contour (10, 20, 30, 40), wherein at least one section (14, 34l, 34r, 44l, 44r) of the wave contour (10, 20, 30, 40) is formed in a helix-shaped manner in the axial direction (RAX). The invention further relates to a metering system (50) with such an actuator module (1).
