conducted toward the outside in accordance with the interconnection of the piezo electrical bodies 11 and 12 as a group a the external connections d and f on the one hand and the external connection c and e on the other hand are connected to one another as a ground terminal the terminals c and e are also connected to the terminal a of the piezo electrical body 10 to be operated in anti phase manner the external terminal be of the piezo electrical body 10 which forms the group b is electrically separated from the common external terminal f of the piezo electrical bodies 11 and 12 of the group a in the case of the variation of fig2 described above on page 10 fig2 a in which instead of only one body 10 a plurality of inside bodies are to be operated in the same phase these form the group b which together like group a likewise consist for example of two piezo electrical bodies fig4 and 5 show respective connection diagrams for an operating circuit of an inventive positioning element the capacitance referenced a in fig4 and 5 represents the piezo electrical bodies of the one group and the capacitance b represents the piezo electrical bodies of the other group whereby the piezo electrical bodies of the one group are to be operated in push pull with respect to those of the other group for the embodiment according to fig3 with outer piezo electrical bodies the capacitance a consists of the parallel connection of two capacitances of the piezo electrical bodies 11 and 12.
