20120091159 | VALVE FOR AERATING AND VENTILATING A TANK - To create a valve for aerating and ventilating a tank comprising a closing element, which is fixed against a valve seat in a closed state so as to form a seal and which is lifted out of the valve seat in an open state, wherein provision is made for a blocking element, which can be moved by means of the force of gravity, by means of which the closing element can be fixed at least in the closed state, which overcomes the disadvantages of the state of the art, which ensures a reliable function even in response to a use under rough conditions with impact loads and which is designed in a simple manner, it is proposed for the blocking element to be accommodated on the closing element so as to be movable. | 04-19-2012 |
20120132170 | STARTING DEVICE FOR AN INTERNAL COMBUSTION ENGINE - A starting device for an internal combustion engine includes a pulley mounted rotatably in a housing which can be set in rotation by a tension means to produce a drive torque for a motor shaft by a starter handle and which is connected to an engaging member by a damping spring. The drive torque is transmitted to the motor shaft to start the internal combustion engine, whereby under torsion of the damping spring, a twisting of the pulley against the engaging member is rendered possible until a stop element impacts against a counter-stop to delimit the twisting, which enables a high operational readiness of the starting device. In the case of a defect of the damping spring, the stop element and/or the counter-stop is formed from a material which has a higher strength than the material of the engaging member and/or the material of the pulley. | 05-31-2012 |
