In addition, a one-piece rocking piston member extends through the two housing components. The piston member carries radially directed wings at one end which are received in the first hollow space while a cylindrical portion is received in the second hollow space for coupling with a crank arm mechanism. The hollow spaces are sealed off relative to each other by a sealing ring which is arranged on the piston member. The piston member is secured in place by a cover member which is bolted to one end member associated with the second housing component. Similar bolt secure the end members associated with the second housing component together. |
