According to the invention, the valve element (20, 20a) has a cut-out, wherein the cut-out (30, 30a, 30b, 30c) has a variable dimension, and a sub region (32, 32a) of the cutout (30, 30a, 30b, 30c) is formed continuously through the valve element (20, 20a).

Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.

The invention relates to a valve for controlling a coolant circuit of a refrigerating system, preferably having a heat pump function, having a housing, which has at least one inlet opening and at least one outlet opening, having a regulating chamber provided in the housing, which extends between the at least one inlet opening and the at least one outlet opening, having a plugging opening provided on the housing, which is adjacent to the regulating chamber, having a valve arrangement, which is insertable at least partially into the regulating chamber, by means of which a current path of a medium between the at least one inlet opening and the at least on outlet opening is controllable, having a rotary slide arrangement, arranged in the regulating chamber, of the valve arrangement, which has a control disc, which is rotatable in relation to the at least one rotary slide support, wherein the at least one rotary slide support is provided non-rotationally to the housing and is allocated to the at least one outlet opening, wherein the at least one rotary slide support is mounted floatingly to the housing.

An air supply device comprises an enclosure, a pump and a flow path switching unit. The flow path switching unit includes a pedestal part, a rotating part having an enclosure interior space communication portion and a groove portion, and a drive unit. The enclosure includes an air supply port, an air discharge port, and at least one object connection port. The pedestal part includes at least one first hole that is communicated to the at least one object connection port, and a second hole that is communicated to the air discharge port. The enclosure interior space communication portion is communicated to the air supply port through an interior space of the enclosure. The groove portion is separated from the enclosure interior space communication portion.

A respiratory system, primarily to provide a mechanical insufflation/exsufflation therapy, may include a first pressure generating source, a second pressure generating source and a primary valve to switch between insufflation/positive pressure flow and exsufflation/negative pressure flow, and to generate oscillations alongside either of these cycles. The respiratory system can optionally employ a secondary valve either on a fluidic path of the first pressure generating source or on a fluidic path of the second pressure generating source. An interfacing assembly acts as a fluidic conduit between the pressure generating sources and the patient. A control unit is configured to generate required pressurized flow and oscillations as per the user settings. The aforesaid valves can be manipulated into multiple orientations/positions, which are aligned and/or adjusted with respect to the respective pressure generating sources as per the therapy requirements.
