A beverage dispenser with a variable pressure regulator cap assembly that includes a high pressure cavity defined by a cap body. The high pressure cavity receives pressurized gas from a compressed gas reservoir. A low pressure cavity is connected to the high pressure cavity via a high pressure gas passageway. The low pressure cavity defines a low pressure gas passageway that penetrates the cap body. A piston seat is positioned on a high pressure cavity side of the high pressure gas passageway. A piston regulates introduction of the pressurized gas into the high pressure gas passageway. A diaphragm is positioned between an ambient pressure cavity and the low pressure cavity and translates the piston relative to the piston seat. A main spring is positioned between a diaphragm and a spring hat. Rotation of the drive screw translates the spring hat to affect compression of the main spring against the diaphragm.

A fluid regulator having a valve body defining an inlet, an outlet, a loading port, an access port, and a loading chamber disposed within the valve body and coupled to the loading port. A valve assembly is at least partially disposed between the inlet and the outlet and in communication with the loading chamber and is adapted to cooperate with the loading chamber to adjust fluid flow at the outlet by adjusting a fluid flow rate between the inlet and the outlet. A restrictor is at least partially disposed within the access port and the loading chamber and the valve assembly are adapted to be responsive to a change in loading pressure such that a modified rate is achieved and the restrictor is adapted to adjust a response speed in which the modified rate is achieved.

An improved structure of an energy-saving precision pressure adjusting valve includes a main body in an interior of which a main membrane and a balance membrane are arranged. The main membrane is operable by an overflow tube and the balance membrane is operable by a pressure-adjusting stein, so that when pneumatic fluid enters the main body, through a channel, a feedback channel and a pressure regulation channel that communicate with each other, together with a feedback channel flow regulation hole and a steel ball arranged in the feedback channel, the pneumatic fluid is allowed to flow in one direction, in combination with stein covering rubber provided on the pressure-adjusting stein and membrane covering rubber provided on the main membrane, the flowing of the pneumatic fluid is made faster and the purpose of fast increase and decrease of pressure and high precision pressure output can be achieved.

A unit (10) for the regulation or control of a fluid pressure, having at least one housing section (13, 14) and a switching film (22) connected to the at least one housing section (13, 14) for switching at pressure differentials relative to an ambient pressure acting on the switching film (22), and for the regulation, release or blocking of a flow of the fluid between an inlet (28) and a discharge (30) for the fluid. The switching film (22) is made out of a polymer material having fluorine and carbon, in particular a thermoplastic having fluorine and carbon. In this arrangement, a hole cross-section (40) of the at least one housing section (13, 14) is closed off by the switching film (22).

A diaphragm actuator (10, 40) for a control valve is shown including an actuator housing (12, 42), in which a diaphragm (14, 44) including a diaphragm disk (16, 46) is sealingly fitted thus forming a pressure chamber (20, 50), and furthermore at least one spring (24, 54) is provided which rests against the diaphragm disk (16, 46) and the actuator housing (12, 42), with the diaphragm disk (16, 46) being connected to a valve stem (22, 52) for actuating a valve body. At least two springs (26, 56) are provided and are disposed one after another in an axial direction between the actuator housing (12, 42) and the diaphragm disk (16, 46), with a spring seat element (28, 58) linearly guided by at least one linear guiding element (30, 60) being provided between the at least two springs (26, 56).

A heater assembly can be used with a gas appliance. The gas appliance can be a dual fuel appliance for use with one of a first fuel type or a second fuel type different than the first. The heater assembly can include at least one pressure regulator, a housing, and an actuation member. The housing has a first fuel hook-up for connecting the first fuel type to the heater assembly, a second fuel hook-up for connecting the second fuel type to the heater assembly, and an internal valve. The actuation member can control the position of the internal valve based on whether the first or the second fuel hook-up is used.

An actuator of a regulator is provided. The actuator is connected to one end of a valve rod (212/312). The actuator comprises a shell (203/303); a limiting component (205/305), the limiting component (205/305) being disposed on an inner wall of the shell (203/303); a diaphragm assembly (204/304), the diaphragm assembly (204/304) being accommodated in the shell (203/303), and the diaphragm assembly (204/304) being movably sleeved on the valve rod (212/312); and an elastic element (226/326), the elastic element (226/326) being accommodated in the shell (203/303), and the elastic element (226/326) being coupled to the diaphragm assembly (204/304), and being movably sleeved, between the diaphragm assembly (204/304) and a tip of one end of the valve rod (212/312), on the valve rod (212/312) in a compressed mode. An inner diameter of a portion, making contact with the shell (203/303), of the limiting component (205/305) is smaller than an outer diameter of an upper portion of the diaphragm assembly (204/304), and the limiting component (205/305) is located above the diaphragm assembly (204/304). A fluid regulator having the actuator is provided. By means of the actuator, the technical problem that a valve rod, a valve flap and a valve port are deformed and even damaged due to extremely large stress in the regulator is solved, the valve rod, the valve flap and the valve port of a valve element assembly are buffered to a certain extent when bearing extremely large stress, and therefore damage is avoided.
