    • A simplified, economical, noise-abating mode of securing a unit embodied for instance as a valve. For securing the unit, the unit has a housing with a first portion having a first encompassing outer face and at least one second portion having at least one second encompassing outer face, wherein a first sealing ring can be mounted on the first outer face, and the first portion and first sealing ring can be introduced into a recess of an installation wall. A second sealing ring can be mounted on the second outer face of the second portion, and the second portion and second sealing ring can likewise be introduced into the recess, so that the support of the unit in the recess is effected by means of the first and second sealing rings without the first and second outer faces of the unit resting on inner faces of the recess. The installation wall has a tubular protruberance, into which the recess extends and which is subdivided, for retaining the unit, into a plurality of bendable ring-snap elements, into which the second sealing ring can be snapped when the unit is introduced into the recess. The unit according to the invention and the snap device for the unit are intended in particular for valves for metered introduction of evaporated fuel into an intake conduit of the internal combustion engine.

    • In a method and an arrangement for checking the tightness of a vessel (10), especially of a tank-venting system of a motor vehicle, the vessel (10) is charged with a pressure generated by a motor-driven pressure source (30) and the motor current is determined. A reference leak (36) is selectively driven by a switchover valve (32) and is charged with a corresponding pressure and the motor current is determined. The determined electrical characteristic quantity and the determined reference characteristic quantity are compared and a conclusion is drawn therefrom as to the presence of a leak. To prevent the entry of moisture into the pressure source (30), it is provided that at least the pressure source (30) is heated intermittently. The heating takes place preferably by driving the switchover valve (32) at a suitable pulse duty factor. To prevent the entrance of moisture into the pressure source (30), a check valve (44) is provided and is suitably mounted in the connecting part of the pressure source (30).
    • 在用于检查船舶(10)的密封性的方法和装置中,尤其是机动车辆的排气系统的容器(10),容器(10)被由马达驱动的压力源(30)产生的压力充满, 并确定电动机电流。 参考泄漏(36)由切换阀(32)选择性地驱动,并对其施加相应的压力并确定电动机电流。 比较确定的电特性量和确定的参考特征量,并从中得出关于泄漏的存在的结论。 为了防止水分进入压力源(30),至少压力源(30)被间歇加热。 加热优选地以适当的脉冲占空因数驱动切换阀(32)。 为了防止湿气进入压力源30,设置止回阀44并适当地安装在压力源30的连接部分中。
