In a switching regulator, input voltage is applied to a primary coil of a transformer through a location between a collector and an emitter of a switching transistor connected in series to the primary coil of the transformer. A pair of output terminals are connected to a secondary coil of the transformer through a rectifier smoothing circuit. A comparator compares output voltage occurring between the output terminals with reference voltage to generate an output signal. On the basis of the output...

A pressure regulator is described including an integral indicator which signals the near depletion of gas in a compressed gas cylinder to which the regulator is connected. The indicator remains extended as long as an adequate supply of gas remains in the cylinder. Upon the near depletion of the gas, the indicator withdraws into the regulator body to warn of the near depletion of gas.

The pressure regulator comprises a valve with a slide member (5) whose displacements are controlled by the pressure prevailing in the control chamber (7). This pressure is adjusted by an obturator (11) of tubular shape which, in its upper position, places the chamber (7) in communication with the opening (4) of the fluid outlet. The fluid is admitted into the valve by an opening (2) and the displacements of slide member (5) permit adjusting the pressure in the opening (3) which supplies a user. ...

The invention relates to a flow regulator for gaseous or liquid media, comprising a housing (1), a regulating unit (1) which changes its free flow area, depending on the flow pressure of the medium, and further comprising a distributor unit (3) behind the regulating means (2) in the direction of flow. To provide a flow regulator which is still relatively simple in construction yet enables more constant volume limitation to be maintained and is less sensitive to manufacturing tolerances of the in...

A pressure regulator comprises a housing internally divided by a diaphragm, the diaphragm carrying a valve closure ball engageable with a valve seat forming part of an outlet from the housing. The ball is located within a ball carrier which is attached to the diaphragm, the ball being retained in the carrier by a ball retainer which comprises an annular disc and engagement means for receiving an end portion of the ball carrier, the ball and the retainer being capable of limited lateral movement ...

A moisture sensing device (2) operating according to the tensiometer principle which in the case of complete drying out emits the same signal as on reaching the maximum moisture content, in the case of complete drying out emits a signal corresponding to that with the minimum, set moisture content. A drying out prevention means (40) provided for this operates with the same contactor (24) and is operated by the same control member (18) as the sensing device (2) in normal operation. The switching p...

A pressure regulator includes a flexible diaphragm which sets-off a liquid chamber having an inlet and an outlet for respectively introducing liquid into and discharging liquid from the liquid chamber under the control of an associated valve through an actuator operated by the movement of the diaphragm. The valve is carried by a coupling which is connected to the housing inlet which, upon the uncoupling of the coupling, allows inspection and/or repair of an associated valve seat or the actuator ...

A window regulator includes a rotatable hub that is coupled to a traveller by a cable, such that rotation of the hub raises and lowers the traveller. The hub is mounted on a driven gear which is rotated by a drive gear. The hub and the driven gear are concentrically mounted around a post, which defines an outer surface that is frictionally engaged by a coil spring that is coupled both to the driven gear and to the hub. The coil spring brakes rotation of the hub when the traveller is pushed downw...

A flush regulator selectively operable in partial flush mode or a full flush mode for use with a water closet including a water storage tank having a flush drain aperture formed in the lower portion thereof and a buoyant flapper valve disposed to selectively seal the flush drain aperture movable between an open and closed position by a flush handle movable between a first and second position to selectively control the flow of water through the flush drain aperture and to dispense bleach or deter...

A mouthpiece for a regulator is of a structure in which it is possible to freely utter words, and to talk even when a driver wears the regulator. The mouthpiece 10 is mounted under a communicating condition on a demand regulator unit 2 which is connected to a cylinder through a hose 4. The mouthpiece 10 comprises a tube 12 abutted against an outer side of a mouth portion of a diver, and a pair of teeth grips 13 extending from the tube into a cavum oris of the diver, so as to be bitten and held b...
