Summary: | The invention relates to a device (6) for pressure-dependent opening of a suction intake (10), comprising a suction jet pump (11), comprising a feed line (12), an outlet line (13) and the suction intake (10); a valve body (15), displaceably arranged inside the feed line (12) in the delivery direction (14) of the suction jet pump (11) and having an effective area (16) exposed to the feed pressure of the suction jet pump (11); and a spring element (17), arranged between the feed line (12) and the valve body (15), for applying a force in opposition to the feed pressure inside the feed line (12); wherein the effective area (16) of the valve body (15), and the spring element (17) are designed so that the valve body (15) closes the suction intake (10) so that it is fluid-tight below a predefined pressure inside the feed line (12) and opens said intake when the predefined pressure inside the feed line (12) is exceeded. The invention further relates to a fuel tank, comprising a device (6) for pressure-dependent opening of a suction intake (10). |
