    摘要： An improved pneumatic jetting valve includes a housing with first and second chambers. A pneumatic piston is enclosed between the chambers. First and second solenoid valves are configured to respectively supply air pressure to the chambers and to exhaust the chambers. A controller is operable to regulate the pressurization and venting of the chambers. The controller controls the timing of control signals for the first and second solenoid valves to control the overlap time during which both the first and second chambers are pressurized. By controlling this overlap time, the controller controls the speed of the drive pin of the jetting valve and thereby the speed at which the valve closes to jet a droplet of material. This allows a valve speed to be selected that is most appropriate for the viscosity of the material being jetted. Numerous new methods for utilizing the improved jetting valve and system are disclosed.

    摘要： Known water supply systems are fed from a source of water such as a tank (6) via a pump (5) to outlets which are occludable by means of a cock (C1-C3). A water pressure sensitive electrical switch (S1) is located downstream of the pump (5) and upstream of the outlets. The switch (S1) is connected in series with an electrical supply for the pump and turns the pump on in response in a drop in water pressure downstream of the switch. Similarly the pump is turned off in response to water pressure downstream to the switch reaching a predetermined minimum pressure, A control system is disclosed in the form of a timer (T) connected in parallel with the pump (5) and energized via the switch (S1). A normally closed safeguard switch (S2) is connected in series with the pump and rendered non-conductive by the timer (T) being energized for a predetermined period. The safeguard switch (S2) prevents the pump (5) operating continuously for more than a predetermine period, typically 15-30 minutes, As a consequence leaks in the system supplied by the pump (5) do not result in excessive water loss from the tank (6), A system and method to prevent water loss in a reticulated town water supply system is also disclosed by means of a flow detector (FD), a timer (T) and a normally open solenoid valve (SV).

    摘要： A rotary valve is described for use in controlling an air supply to an inflatable patient support system, especially an alternating pressure mattress. The valve comprises a rotary valve for controlling air supply to an alternating pressure patient support system which comprises a body member (10) having a planar surface (21) and at least two apertures (25, 26) for communication with cells or sets of cells in the patient support system, and a further aperture (22) for connection to a pressurised air source, an actuator member (12) which is rotatable in face to face contact with said planar surface, said actuator having a recessed portion (38) which forms an air supply chamber when in contact with said planar surface is positioned to be constantly supplied with air from said further aperture, drive means (16, 18) for rotating the actuator with respect to the first member and detector means (32) for detecting the position of the actuator relative to the body member and, in conjunction with control means, for controlling the timing and duration of air supply to the cells or sets of cells.

    摘要： A cleaning valve drive unit constituted to be able to supply water to a toilet by manual rotational operation of a main shaft in which the main shaft is constituted to be able to pull out from a cleaning operation position to a draining operation position. Whereas an operation limiting mechanism with respect to the main shaft enables to carry out cleaning operation to the toilet by rotational operation around an axis line with respect to the main shaft when the main shaft is disposed at the cleaning operation position, when the main shaft is moved to the draining operation position, the operation limiting mechanism permits to drain water by the rotational operation around the axis line with respect to the main shaft.

    摘要： A multi-port rotary disc valve comprising a stator with a plurality of fluid flow ports and a rotary distributor with a plurality of channels arranged in a channel pattern. The channels are adapted to connect the ports between them and/or to the environment in a plurality of predetermined combinations, each combination being associated with an angular position of the rotary distributor with respect to the stator. The succession of combinations performed during a full or partial unidirectional turn of the rotary distributor constitute a predetermined sequence. The rotary distributor comprises a rotor and a mask mounted movably thereon, the rotor and the mask accommodating the plurality of channels. The mask is adapted to change the channel pattern by changing its position with respect to the rotor, thereby enabling the rotary disc valve to perform different predetermined sequences corresponding to different positions of the mask.
