摘要:
The present invention relates to an arrangement for controlling fluid flow through an aperture. In one embodiment, the flow control arrangement, which may be used in association with a window to control the flow of ventilating air, comprises a strip brush composed of an array of resilient filaments (1) firmly mounted at their root region (2). The free end region (3) of the filaments (1) define, with a fixed flange (7), the effective area or width (9a) of an aperture (6) for the passage of ventilating air in the direction of the arrow (11). Variations in the strength of the air flow incident to the array of filaments causes changes in the degree of deflection of the filaments, thus altering the effective width (9a) of the aperture and controlling the air flowthrough the aperture.

The invention relates to a control device (1) for controlling airflows in motor vehicles, comprised of a frame having at least one passage opening (4) and at least one controlling means, which is provided in the form of a roller louver (5) and which serves to modify the passage cross-section for the air flowing through the passage opening (4). The frame comprises a housing (2) with at least two hollow bodies (8) that are open along the longitudinal sides. These hollow bodies (8) accommodate the drive shaft (6) or the return shaft (7) for the roller louver (5), and each have a pivotal cover (8.3) for opening the respective hollow body (8). The control device (1) can be mounted inside airflow ducts of a heating and/or air-conditioning system for motor vehicles.

摘要:
A leaf spring valve which is capable of being opened and closed assuredly and stably with a small operating torque by having a stored springing force in a valve disc itself, reducing a cost, and being manufactured compact, and being excellent in durability and high in practical use value, and which further provides a constant flow function to the valve disc itself having a sealing function for multi-functionability, provides various types of constant flow functions according to the number of rotations of the spring, and can controllably open and close a flow path for fluid, wherein one end of a main spring (47) is installed inside a valve chamber (42) of a valve box (41), the other end is installed on a valve stem (52) in the valve chamber (42), the side face of the main spring (47) is disposed opposedly to and pressingly against a valve seat (42a) of the valve box (41), and the valve stem (52) is rotated by an actuator (55) to displace the main spring (47) toward the center of the valve stem (52), whereby the side face of the main spring (47) is moved apart from the valve seat (42a) to open a secondary side flow path port (44).

An electrically controllable valve comprising at least one input port (13) and one or more output ports (12, 14), at least one sealing means (17, 18) being arranged to control the flow of a fluid between said input port and at least one of said output ports, said valve further comprises one or more piezo-electric actuators (26) arranged to control the state of said sealing means, whereby the flow of fluid through said valve may be electrically controlled.

A tank vent valve apparatus includes a valve housing formed to include an inlet port, an outlet port, and an interior region. The interior region is partitioned to define an intake chamber communicating with the inlet port, a discharge chamber communicating with the outlet port, and a float chamber containing a vent port valve and receiving liquid fuel and fuel vapor from the intake chamber. An interior wall defines a boundary between the float chamber and the discharge chamber and includes a valve seat formed to include a vent port therein. The vent port valve is buoyant and moves up and down along the interior wall as liquid fuel rises and falls in the float chamber to close and open the vent port.

This invention relates to a pressure compensating valve and more particularly, but not exclusively, to a balanced pressure compensating valve, or regulator. The valve includes a chamber (6) for containing fluid, defined by a flexible barrier (2) trapped between first (3) and second (4) surfaces. A fluid inlet provides fluid to the interior of the chamber. A fluid outlet selectively allows fluid to pass out of the chamber. Movement of the first (3) and second (4) surfaces relative to each other causes change in contact between the flexible barrier and the first and second surfaces to selectively open the fluid outlet, in a first position, and occlude it between the flexible barrier and one of the surfaces, in a second position.
摘要:
A band controlled valve apparatus for controlling fluid flow from a source to a sink, including a base (12) having an upper surface and an aperture (16) extending from the upper surface through the base (12) allowing the flow of fluid from the source through the base (12) to the sink when the aperture (16) is not covered, an elongate flexible band (8) with a first portion (8a) in contact with the upper surface of the base (12) and a second portion (8b) extending forwardly of the first portion (8a) then upwardly and rearwardly above at least a part of the first portion (8a), the second portion (8b) being actuated to selectively move the second portion (8b) of the band (8) forwardly or rearwardly to cover or uncover, respectively, the aperture (16) with the first portion (8a) of the band (8) to thereby prevent or allow, respectively, fluid flow through the aperture (16).
