The invention relates, among other items, to a device (10) with a plurality of inlets (27a, 27b, 27c, 27d, 27e, 27f) and one outlet (19), wherein each of the inlets (27a, 27b, 27c, 27d, 27e, 27f) can be connected to a material supply container (13a, 13b, 13c, 13d, 13e, 13f). An actuator (12) that can be displaced relative to the inlets and has a through-channel (42) is furnished in order to provide a switchable connection between one of the plurality of inlets and the outlet. A communicative connection can be created between the through-channel and one of the various inlets in order to allow various materials to be successively supplied to the outlet. One of the characteristic features is that at least one of the inlets (28) is designed as a flushing medium inlet of a flushing device (47) and that, as a result of the actuator (12) being displaced, a communicative connection can be created between the through-channel (42) and the flushing medium inlet for the purposes of flushing the through channel.

The present invention discloses an intelligent thermostatic water outflowing device in the field of sanitary wares. By using said intelligent thermostatic water outflowing device, the defects of the current thermostatic water outflowing devices are overcome, such as a relatively complicated whole structure, a high cost and a poor applicability to ordinary valves. The intelligent thermostatic water outflowing device of the invention comprises a body provided with a hot water inflowing passage, a cold water inflowing passage and a water outflowing passage, and a valve core assembly provided between the cold water inflowing passage, the hot water inflowing passage and the water outflowing passage within the body. The present device further includes a motor, a water temperature control circuit and a temperature sensor. The valve core rod of the valve core assembly is connected with the output shaft of the motor fixed within the body. The temperature sensor is placed in the water outflowing passage and connected with the water temperature control circuit. The water temperature control circuit is connected with the motor and has an external power source connected thereto for supplying the power. The operation of the motor could be controlled by the water temperature control circuit according to the outflowing water temperature detected by the temperature sensor. The device has advantages such as a high precision, good safety and an excellent visual effect.

A hybrid valve apparatus for use with an aspiration actuator and a dispensing actuator to transfer fluid from a reservoir to a test site on a substrate surface. The hybrid valve includes a valve assembly movable between an aspiration condition and a dispensing condition, and a manifold device coupled to the valve assembly. The manifold device includes a fluid aspiration conduit having a first aspiration port in fluid communication with the aspiration actuator. On an opposite end of the aspiration conduit is a second aspiration port in selective fluid communication with the valve assembly to selectively aspirate a liquid sample slug from the reservoir into a discrete sample path when the valve assembly is in the aspiration condition. The manifold device further includes a fluid dispensing conduit having a first dispensing port in fluid comanunication with the dispensing actuator, and a second dispensing port in selective fluid communication with the valve assembly. When the valve assembly is in the dispensing condition, the sample path is fluidly coupled to the dispensing actuator to selectively dispense at least one droplet of the liquid sample slug therefrom, while simultaneously being out of fluid communication with the aspiration actuator. In contrast, in the aspiration condition, the sample path is in fluid communication with the aspiration actuator, while being out of fluid oommunication with the dispensing actuator.

A rotary shear valve having three-point stator seating is provided. Three contact points are predetermined between a bottom of the stator and a valve body rim and three clamping pads may also be predetermined. The three clamping pads and the three points of contact between stator and the valve body rim are corresponding and aligned when the rotary shear valve is assembled so that the clamping or compression forces on both sides of the stator directly oppose one another, thereby effectively canceling each other. In one embodiment, the stator includes three contact points on the bottom surface proximate the periphery of the stator to contact the valve rim and a gasket includes three clamping pads proximate the periphery of the gasket web to apply a compression force on the top surface of the stator above the three contact points.
