摘要： A valve actuator (20) is provided. According to an aspect of the disclosure, a valve actuator (20) comprises a housing (110), a motor (120) disposed on the housing, a drive gear (130) coupled to a motor shaft of the motor, a transfer gear (140) engaging with the drive gear and rotating according to a predetermined gear ratio when the drive gear rotates, an output gear (170) coupled to an output shaft and engaging with the transfer gear, and a stopper (190) disposed in the housing and limiting a rotation radius of the output gear (170). The transfer gear (140) includes an outer part (141), an inner part (143) disposed inside the outer part, a first magnet (210) disposed on the outer part, and a second magnet (220) disposed on the inner part and facing the first magnet. Thus, it is possible to prevent damage to the gears due to over-torque or contact between the output gear and the stopper.

摘要： Check valve units having one or more sound attenuating members are disclosed. A check valve unit includes a housing defining an inlet port, an outlet port, and a chamber in fluid communication therewith thereby defining a flow path from the inlet port through the chamber to the outlet port. The chamber includes first and second valve seats and has a sealing member disposed therein that is moveable from a position seated on the first valve seat to a position seated on the second valve seat. A sound attenuating member is disposed in the flow path downstream of the chamber, within the chamber, or both. In another embodiment, the check valve unit includes a Venturi portion in fluid communication with the chamber. The Venturi portion has a fluid junction with the flow path downstream of the chamber or forms the discharge section of the Venturi portion thereby defining the outlet port.

摘要： The invention is directed to a valve actuating device comprising a body with a bore and a bottom, an actuating element sealingly housed in the bore of the body and forming a first chamber with the body, a piston sealingly extending through a bore in the actuating element, the piston and bore delimiting a second actuating chamber, a passage for an auxiliary fluid between the first and second chambers so that a movement of the piston in the bore of the actuating member can increase the pressure in the first chamber and move the actuating element. The fluid passage comprises a restriction and a check-valve, both arranged in parallel, so as to limit the flow of the auxiliary fluid from the second chamber to the first chamber.
