    摘要： The invention relates to an actuator (10) for actuating a device in a linear manner by means of a tangential rod which can be displaced in a longitudinal manner by converting the torque of a motor-driven pinion (32), in particular for a flap or for a valve in the field of heating-ventilation-climatisation (HLK), or fire and smoke protection. According to the invention, a normal threaded rod (24) which can be displaced in the axial direction thereof (L) and which can be cut to an individual length, has a radius (r) which is rotationally secured in the actuator (10). The pinion (32) in connected in a positive fit to at least one drive wheel (36) which is mounted in a freely rotational manner, and an elastic and/or adjustable pressure element (38, 54, 64, 66) which carry out a play-free engagement of drive wheels (36) and the normal threaded rod (24).

    摘要： The invention provides valves of the type employing a differential pressure regulator and a characterized valve with a mechanism to enhance control of fluid flow independently of system pressure. The valves of the invention are especially suitable for HVAC applications, and provide operation with improved accuracy over a greater flow range with a reduced risk of hunting. In one preferred aspect, the invention provides improvements by the employment in the differential pressure regulator of a diaphragm with a cup arranged to provide a small leakage, thereby dampening the response of the regulator. In another aspect, a baffle is provided to protect the downstream side of a control disk forming part of the differential pressure regulator.

    摘要： The invention relates to a device (10) for controlling airflow (A) in a ventilation pipe (12) comprising one or several air throttle (32) which are synchronously actuated and prevent air flowing (A) in the air pipe in the closed position thereof. The ventilation pipe (12) is provided with a longitudinally extending fixing bar (16) which is arranged on a symmetry plane and provided with the pivot bearing (30) of an axis (28) for driving the air throttle(s) (32) and means (50, 52) for transmitting a force and/or torque to the drive axis (28) connected to the air throttle(s) (32). Said fixing bar (16) provided with different air throttles (12) is usable for the ventilation pipes having different cross sections and forms, an angle (β), preferably, ranging from 15° to 90°, with a longitudinal axis (L) or with a wall (18) of said ventilation pipe (12).

    摘要： A linear actuator (2) for use in HVAC applications comprises an actuator housing (20); and an adapter having a first clamping jaw (3a) and a second clamping jaw (3b) for fixing the linear actuator to a globe valve. In order to prevent formation of ice in or on the surfaces of the globe valve when environmental temperatures are below 0° C, active heating is required. For this purpose a heating pad (5) made of silicone is fixed to the first clamping jaw (3a) and the second clamping jaw (3b).
