Abstract (en)
The buffer is held at least in the main thrust direction at a distance from the walls of a chamber (6) in the housing accommodating the transmitter (14). The transmitter is embedded in the buffer. The buffer has a larger diameter than the transmitter. One buffer is positioned at each end of the transmitter. The buffers have ring grooves, and are fixed to the transmitter by means of at leat one pin engaging in a hole (18) in the buffers. A rear cut (19) is provided in the hole. The buffer has externally a longitudinal groove (22), in which engages a projection (23) on the housing (2) accommodating the transmitter as securement against rotation. At the other end of the transmitter is a slot (24) accessible through the hole in the buffer for positioning by means of a tool.
