PCT No. PCT/FI84/00037 Sec. 371 Date Jan. 7, 1985 Sec. 102(e) Date Jan. 7, 1985 PCT Filed May 17, 1984 PCT Pub. No. WO84/04803 PCT Pub. Date Dec. 6, 1984.The present invention concerns a way and a means for rendering equal the effect of gravity independent of the mode of installation in flow regulators for gaseous substances, particularly for air in air-conditioning and ventilation installations, and for maintaining the volumetric flow of the gaseous substance at desired magnitude with sufficient accuracy when the differential pressure acting across the flow regulator varies within given limits. The flow regulator comprises an envelope and a regulating member turnably disposed in the flow passage confined by the envelope. The torque produced by the flow of gaseous substance on the regulating member and on the other hand a countertorque dependent on the position of the regulating member cause the regulating member turning in the flow passage to assume a position of equilibrium such that the requisite pressure drop is obtained for maintaining the volumetric flow rate at predetermined magnitude. The regulating member is first balanced, e.g. in connection with manufacturing, without countertorque dependent on the position of the regulating member. Thereafter, a member providing the countertorque by its mass is reset by turning the member about the turning axis of the regulating member as much, but in the opposite direction, as the current mode of installation deviates from the basic installation. The means comprises a member supporting the weight providing the countertorque by its mass, connected to a turnably disposed member. In a mode of installation deviating from the basic installation, the member supporting the weight may be turned with reference to said turnably disposed member.
