Abstract: A valve with a pilot control is provided for a fuel vapor retention system. The valve has a main valve (10) with a valve body (12) for opening and closing a fluid passage, a pilot control valve (20), which is arranged at the valve body (12) for opening and closing a channel (14) arranged in the valve body (12) and has an elastically deformable diaphragm (22), and a plunger (30) for pressing the diaphragm (22) against a mouth of the channel (14) to close the channel (14) thereby and displacing the valve body (12) in the closing direction against a valve seat (11).

Abstract: A valve for limiting the tank pressure in a motor vehicle, comprising a first line (1) and a second line (2) which may establish a flow connection in which at least one body (3, 4) may be moved relative to another body (4, 3), whereby the movable body (3, 4) lifts up from a sealing seat (5), with regard to the object of adjusting the tank pressure using a compact design is characterized in that a first body (3), a second body (4), and the sealing seat (5) as a whole form a movable unit (6).

Abstract: A valve includes a housing having an inlet (3), an outlet (1) and a movable sealing member (2) which allows the inlet (3) and the outlet (1) to be connected in fluid communication with each other, the sealing member (2) having associated therewith effective areas (4b) to which pressure can be applied, and sealing areas (4), and the sealing member (2) further having associated therewith a sealing seat (4a) for sealing the inlet (3) from the outlet (1). In order to provide a valve by which pressure can be relieved in a very short time, the sealing member (2) has associated therewith a conduit (2a) by which the inlet (3) and the outlet (1) can be connected in fluid communication with each other when the sealing member (2) rests on the sealing seat (4a).

Abstract: A valve is provided comprising a housing, said housing containing a channel for a fluid medium, and the channel having associated therewith a sealing element which cooperates with a sealing seat. Said sealing seat is positioned in a chamber with which are associated a particle retention element in order to provide simplicity in construction and ease of installation. Said valve is designed and improved in such a manner that, once installed, it ensures optimal operation at all times while being simple in construction and easy to install.
