Problems solved by technology

However, to keep the valve biased in the closed position, these solutions require an additional force (besides the resiliency of the lip) to be substantially perpendicular to the flow path

Embodiment Construction

[0037]Figure 1 to 5 A valve 1 according to a preferred embodiment is illustrated. inFigure 1 to 5 In, the valve 1 is in a non-installed state.Figure 6 withFigure 7 An example is shown in which valve 1 is mounted to surface 2. inFigure 6 withFigure 7 In the case where the valve 1 is in the installation state.

[0038]Such asFigure 6 withFigure 7 As shown, the valve 1 is generally suitable for mounting to the surface 2 or assembled with the surface 2, and the flow path 3 flows through the surface. The flow path 3 can be defined by valve 1. For example, the flow path 3 can be aligned with the axis of the valve 1, such as the symmetric axis of valve 1. The surface 2 can include a through hole 4 that facilitates the flow path 3 to flow through the surface 2. The through hole 4 is generally defined or defined by the surround side edge of the surface 2. For example, through holes 4 can have a substantially circular shape. In other examples, through holes 4 may have different shapes such as el...

Abstract

The invention relates to a valve (1) for mounting to a surface (2) and for use in a flow path, which flows through said surface (2), for permitting flow in said flow path in a first direction and for preventing flow in said flow path in a second direction being opposite to the first direction. The valve (1) comprises: one or more ports (21) defined by a plurality of lips (22), wherein each lip (22) is resiliently deformable from a first position, in which the lips (22) are in contact with one another in order to close the respective port (21), to a second position, in which the respective port (21) is opened in order to permit flow in the first direction, and one or more contacting structures (30) arranged to mechanically contact the surface (2), when the valve is mounted to the surface (2), such that the one or more contacting structures (30) bias the lips (22) into the first position.

Description

Technical field[0001]The present invention relates to a valve that allows flowing in the first direction in the first direction in the flow path to flow in the flow path.Background technique[0002]Valves according to the above types may be a one-way valve such as a duck spool valve. Such valves can be used in many fields such as automotive, industrial equipment, healthcare, etc. Generally, the valve or duck spool valve is an elastically deformed fluid one-way valve comprising a retractable lip for forming, for example, a valve port in the form of a seam. The valve is typically biased to the closed position, and the deformable lip is held in or off position when the valve is in a no-load state. When the pressure is applied to the inlet side of the valve, or when the mechanical member is topped onto the valve lip, the retraction of the elastic lip is opened and the valve port is opened, allowing fluid to flow in the first direction. When the pressure is not applied to the inlet side or...
