Abstract
The invention pertains to a three-way valve (1), particularly one intended to be used in an air intake circuit of a motor vehicle, comprising: a body (200) delimiting a first (2), a second (3), and a third (4) conduit, said conduits opening into a shared inner space (201), a first flap (21) capable of being moved to obstruct the first conduit, a second flap (20) capable of being moved to selectively obstruct either the second or the third conduit, a single actuator being arranged to selectively move at least one of the first and second flaps.
Claims10
A three-way valve for an air intake circuit of a motor vehicle, comprising:
- a body delimiting a first conduit, second conduit and third conduit, the conduits opening in a common internal space;
- a first valve member which is capable of being moved in order to close the first conduit;
- a second valve member which is capable of being moved in order to selectively close one or other of the second and third conduits;
- a single actuator which is arranged in order to selectively move at least one of the first and second valve members;
- a first transmission wheel, which is arranged in order to carry the first valve member;
- and
- a second transmission wheel, which is arranged in order to carry the second valve member,
- wherein the actuator comprises an actuation wheel that is arranged in order to directly engage one of the first and second transmission wheels and indirectly engage the other of the first and second transmission wheels, such that either the actuation wheel directly engages the first transmission wheel and the first transmission wheel directly engages the second transmission wheel, or the actuation wheel directly engages the second transmission wheel and the second transmission wheel directly engages the first transmission wheel,
- the actuation wheel being arranged in order to directly engage the second transmission wheel and to indirectly engage the first transmission wheel via at least the second transmission wheel,
- the valve being configured so that:
- from a rest state of the first and second valve members, a rotation in a first rotation direction of the actuation wheel brings about a movement of the first valve member without moving the second valve member;
- and
- from the rest state of the first and second valve members, a rotation in a second rotation direction of the actuation wheel, counter to the first rotation direction, brings about a movement of the second valve member in accordance with a first step without moving the first valve member.
