Definitions
- the invention relates to a volume flow controller for air conditioning and ventilation systems with a flap pivotable in a flow channel, the pivot shaft of which has a lever arm on which a spring articulates.
- Such volume flow controllers are known in various designs. They work mechanically automatically because the flow-related flap torque is compensated by the spring. When the flow conditions change, the swivel position of the flap also changes. However, the prerequisite for this is that the spring must be specially calibrated for each controller.
- the object of the invention is to provide a mechanically automatic volume flow controller in which the spring can be adapted to the control process by simple adjustment.
- the spring is a leaf spring, one end of which is connected to the lever and the other end is thus fastened to a cam disk is that when the cam disk is adjusted about a pivot point, the leaf spring is carried along by the cam disk and rolls on the curve, and that a device is provided for fixing the cam disk.
- it is sufficient to turn the cam disc around its pivot point until the leaf spring has reached the desired spring preload.
- the spring constant and the direction of force application also change. After adjusting the cam disc to the desired setpoints, this position of the cam disc is fixed.
- a preferred embodiment of the invention is characterized by an arrangement such that the relaxed leaf spring extends essentially orthogonally to the flow channel.
- a flow channel 1 can be seen with a flap 3 arranged therein on a swivel shaft 2, which, based on its basic position shown in dashed lines and the effect of flow forces of the air flow 6 and against the action of a spring 5 in the direction the arrow 4 is pivotable.
- a cam disk 8 is mounted on the flow channel 1 so as to be pivotable about a pivot point 7 and can be fixed with a direction (not shown) for fixing in different pivot positions.
- the spring 5 is attached, which is designed as a leaf spring.
- the other end of the spring 5 is articulated to a connecting rod 10 or a connecting cable with a lever 11 which sits on the pivot shaft 2 of the flap 3.
- the relaxed spring 5 is shown with solid lines, which then extends essentially orthogonally to the flow channel 1 or to the flow direction.
- a functional position is shown with dashed lines, in which the cam plate 8 has been pivoted by a certain angle in the direction of the arrow 12.
- the leaf spring 5 rolls on the curve 9 of the cam 8, whereby its end connected to the connecting rod 10 experiences a deflection.
- the spring constant, the spring preload and the direction of force application on the lever 11 change.
