Valve device for an internal combustion engine

摘要

A valve device for an internal combustion engine includes a housing with an inlet and an outlet, a passage opening which fluidically connects the inlet with the outlet, a first valve-closing member which controls the passage opening, an actuator, a valve rod on which the first valve-closing member is arranged, a stop element, a spring surrounding the valve rod, and an element. A first end of the spring is supported against the first valve-closing member, and a second end of the spring is supported against the stop element. The element substantially surrounds the spring. The element comprises a first lateral surface and a second lateral surface in mutual engagement with each other. The first lateral surface abuts against the first valve-closing member and is movable therewith. The second lateral surface abuts against the stop element. The first valve closing member moves relative to the stop element.

1. A valve device for an internal combustion engine, the valve device comprising:
a housing comprising at least one inlet and an outlet; at least one passage opening configured to fluidically connect the at least one inlet with the at least one outlet; a first valve-closing member configured to control the at least one passage opening; an actuator; a valve rod on which the first valve-closing member is arranged, the valve rod being configured so as to be translationally movable by the actuator; a stop element; a spring surrounding the valve rod, a first end of the spring being supported against the first valve-closing member, and a second end of the spring being supported against the stop element; an element configured to substantially surround the spring, the element comprising a first lateral surface and a second lateral surface which are configured to be in mutual engagement with each other and to slide with respect to each other, the first lateral surface being arranged to abut against the first valve-closing member and being configured to be movable therewith, and the second lateral surface being arranged to abut against the stop element, the first valve closing member being configured to move relative to the stop element; a first pot-shaped part consisting of a first bottom and the first lateral surface formed integrally therewith; and a second pot-shaped part consisting of a second bottom and the second lateral surface formed integrally therewith, wherein, the first bottom and the second bottom each have the valve rod extend therethrough, and the spring presses the first bottom against the first valve-closing member and the second bottom against the stop element.
