摘要： To control the flow of a fluid from an environment to a vacuum source, a device including a piston (2) is mounted in the path of the fluid. The path is not vented so that the mass of fluid entering the device is equal to the mass exiting the device. The piston (2) is mounted so that it may constrict the path at a constriction point (5), and so that it may move in a direction (14) transverse to the flow the fluid at the constriction point (5). The frontal face (15) of the piston (2) is exposed to the fluid in the path, and the distal face (16) of the piston (12) is exerted on the piston (2) so as to tend to widen the path at the constriction point (5).

摘要： A way and 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, for maintaining the volumetric flow of the gaseous substance at desired magnitude with sufficient accuracy when the differential pressure acting across the flow regulator (10) varies within given limits. The flow regulator (10) comprises an envelope (11) and a regulating member (12) turnably disposed in the flow passage confined by the envelope (11). The torque produced by the flow of gaseous substance on the regulating member (12) and on the other hand a countertorque dependent on the position of the regulating member (12) cause the regulating member (12) 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 (12) is first balanced, e.g. in connection with manufacturing, without countertorque dependent on the position of the regulating member (12). Thereafter, a member (23) providing the countertorque by its mass is reset by turning the member (23) about the turning axis (13) of the regulating member (12) as much, but in the opposite direction, as the current mode of installation deviates from the basic installation. The means comprises a member (20) supporting the weight providing the countertorque by its mass, connected to a turnably disposed member (19). In a mode of installation deviating from the basic installation, the member (20) supporting the weight (23) may be turned with reference to said turnably disposed member (19).

摘要： A flow-controlling unit provided in a flow channel is disclosed. The flow-controlling unit provided in a flow channel, according to one embodiment of the present invention, comprises: a plate which is disposed perpendicular to the moving direction of a fluid in a flow channel, and on which are formed multiple fluid through-holes through which the fluid passes; and one or more flow-controlling pieces which are provided in a position corresponding to the fluid through-holes, form an inclination with respect to the plate in the direction of the inflow of the fluid, are capable of tilting on the plate, and control the degree of opening of the fluid through-holes by being tilted due to pressure applied from hydraulic pressure of the fluid.

摘要： A ball valve has a cartridge comprising a sleeve (38) and constant flow regulator device (44) inserted into a bore (34) through the ball (20). A further constant flow regulator (50), of higher flow rating, is located in an outlet port (14) of the valve. When the ball bore is aligned with the flow axis, all flow passes through the ball bore and the lower flow rating regulator (44) is dominant. At 45° to the flow axis, flow by-passes the ball, passing through a surrounding ball chamber (18), and the flow rate is determined by the higher flow rating regulator (50). In the closed condition of the valve the cartridge can be extracted from the ball bore through an aligned access port (16) for maintenance or exchange of the lower rating regulator.

摘要： Afin de commander l'écoulement d'un fluide d'un environnement à une source de vide, un dispositif comprenant un piston (2) est monté dans le chemin du fluide. Le chemin n'est pas purgé de sorte que la masse de fluide pénétrant dans le dispositif est égale à la masse sortant de ce dernier. Le piston (2) est monté de manière à pouvoir rétrécir le chemin en un point de rétrécissement (5), et de manière à pouvoir se déplacer dans un sens transversal (14) par rapport à l'écoulement du fluide au point de rétrécissement (5). La face frontale (15) du piston (2) est exposée au fluide se trouvant dans le chemin, et la face distale (16) dudit piston (12) pousse le piston (2) de manière à tendre à élargir le chemin au niveau du point de rétrécissement (5).

摘要： The present invention concerns a flow regulator for gaseous substances, particularly a flow regulator intended for air in air-conditioning and ventilation installations, 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 substantially slightly curved at least in the flow surface facing the incoming flow of the gaseous substance. The turning angle between the initial and ultimate positions of the regulating member is substantially the same at volumetric flows of different magnitudes when the differential pressure range is the same. The initial and ultimate positions of the regulating member are dependent on the magnitude of the volumetric flow when the differential pressure is the same.

摘要： A hydraulic pump assembly comprises a rotatable piston drum (20) with at least one centrifugal lever (23) pivotally attached thereto for radial movements between radial flanges (20′) under the action of centrifugal force at rotation of the piston drum. The centrifugal lever (23) is arranged to control the position of a valve member, preferably a ball (22), at the opening end of a bore (21) in the piston drum (20). There is a defined friction surface (28; 32) between the lever (23) and one of the radial flanges (20′), and there are spring means (29-31; 25, 33) for resiliently biasing the lever against said one of the flanges.
