Suction device

A suction device, comprising:

• a suction channel body defining a suction channel, the suction channel body including a first suction portion and a second suction portion disposed opposite one another in a transverse direction;
• the first suction portion including:
• a first guide cage having a closed end and an open end;
• and
• a first valve including (i) a first valve seat connected to the open end of the first guide cage and (ii) a moveable first valve body disposed in the first guide cage and configured to interact with the first valve seat to seal a first end of the suction channel;
• the second suction portion including:
• a second guide cage having a closed end and an open end;
• and
• a second valve including (i) a second valve seat connected to the open end of the second guide cage and (ii) a moveable second valve body disposed in the second guide cage and configured to interact with the second valve seat to seal a second end of the suction channel;
• wherein the first valve and the second valve are configured such that:
• when a transverse acceleration is equal to or greater than a predefined transverse acceleration, one of the first valve and the second valve closes while the other one of the first valve and the second valve remains open;
• and
• when the transverse acceleration is less than the predefined transverse acceleration, the first valve and the second valve are both open;
• wherein, via the transverse acceleration, the first valve body is movable within the first guide cage and the second valve body is movable within the second guide cage;
• wherein the first guide cage includes a plurality of elongated first openings longitudinally extending transverse to a first central axis of the first valve seat;
• wherein the second guide cage includes a plurality of elongated second openings longitudinally extending transverse to a second central axis of the second valve seat;
• wherein the first guide cage further includes a first cage half and a second cage half that are connected to one another to define the first guide cage;
• wherein the first cage half includes (i) a first base body, (ii) a plurality of first ribs projecting from the first base body, and (iii) a first end wall projecting from the first base body;
• and
• wherein the second cage half includes (i) a second base body, (ii) a plurality of second ribs projecting from the second base body and contacting the plurality of first ribs, and (iii) a second end wall projecting from the second base body and contacting the first end wall.

• when the transverse acceleration is in a first direction and is equal to or greater than the predefined transverse acceleration, (i) the second valve is closed and (ii) the first valve is open;
• and
• when the transverse acceleration is in a second direction opposite the first direction and is equal to or greater than the predefined transverse acceleration, (i) the first valve is closed and (ii) the second valve is open;
• wherein the first guide cage includes a first cage half and a second cage half that are connected to one another to define the first guide cage;
• wherein the first cage half includes (i) a first base body, (ii) a plurality of first ribs projecting from the first base body, and (iii) a first end wall projecting from the first base body;
• and
• wherein the second cage half includes (i) a second base body, (ii) a plurality of second ribs projecting from the second base body and contacting the plurality of first ribs, and (iii) a second end wall projecting from the second base body and contacting the first end wall.
