The present invention relates to a valve system, comprising a first valve and a second valve, wherein both valves each have a housing with a plurality of housing openings, and a valve body arranged rotatably in the housing with at least one connection channel for providing a fluid connection of at least two of the housing openings,

characterized in that
the valve body of the first valve and the valve body of the second valve are mechanically coupled with each other by means of a coupling device of the valve system, wherein the coupling device is designed in such a way that the valve bodies can be rotated jointly by means of the coupling device when the valve system is in a first operating state and rotated independently of each other by means of the coupling device when the valve system is in a second operating state.

The present disclosure relates to an actuator, an actuator assembly, a method of operating an actuator, a computer program and a system. In one aspect, an actuator may comprise a plurality of independently operable actuation elements and an operator having an operator surface. Each actuation element may have an actuation surface. The operator may be driveable to move the operator surface along a path to selectively engage with the respective actuation surface of each actuation element to actuate the actuation element.

A thermostat valve includes a housing with several cooling fluid connections, at least two hollow valve elements mounted rotatably next to one another in the housing on a common rotational shaft, each having at least one opening selectively couplable to one or more of the cooling fluid connections by way of rotation of the valve elements, and a rotational drive for a first of the valve elements can be driven rotationally in the housing, a second of the valve elements can be selectively coupled to or decoupled from the first valve element, the second valve element driven rotationally, when it is coupled to the first valve element, and a coupling element mounted axially movably on the rotational shaft, and a coupling drive by way of which the coupling element can be moved axially on the rotational shaft between a coupling position and a decoupling position.

A hot and cold water switching valve includes a valve body, a switching valve element, a switch valve element and a thermal sensing valve element, wherein the valve body has an inflow channel, a recovery channel and an outflow channel; one end of the three channels is communicated in the valve body; the switching valve element is provided in such a position where the three channels are communicated with each other and used for switching the outflow mode; the switch valve element is provided in the outflow channel and used for opening or closing the outflow, and the thermal sensing valve element is provided in the recovery channel and used for closing the channel when the water temperature is higher than the set temperature; and a sprinkler used for automatic outflow of cold water, comprising a sprinkler body and the above-mentioned hot and cold water switching valve.

A valve assembly has a port selection assembly with an inlet fluid path and a plurality of outlet fluid paths and a servo-driven barrel. The barrel includes a slot that is aligned with the inlet fluid path. The barrel also includes multiple pockets. The valve assembly also includes ball seals, each of which is at least partially disposed within a respective pocket. The rotation of the barrel moves the ball seals to block or unblock one or more of the outlet fluid paths, thereby controlling the flow of fluid from the inlet fluid path, through the slot, and through the outlet fluid path.

An example valve section includes: a valve body configured to be fluidly coupled to the source and the actuator; a spool movable in the valve body intermediate the source and the actuator; a pressure compensator valve disposed upstream from the spool and configured to regulate flow received from the source, where the valve body defines (i) a first passage disposed upstream from the spool and configured to fluidly couple the pressure compensator valve to the spool, and (ii) a second passage disposed downstream from the spool and configured to fluidly couple the spool to the actuator; and a counterbalance valve disposed in the second passage downstream from the spool, where the counterbalance valve is opened to permit flow therethrough from the actuator to the spool in response to a pilot pressure derived from the first passage when the spool is shifted from a neutral position.

A valve having a housing in which three ducts that are connected to each another are arranged, one flap, which is mounted rotatably on a shaft is arranged in each of two ducts, an electric motor which drives a shaft by a gearing system, and a transmission mechanism, which drives the second flap depending on the movement of the first flap. On the shaft of the first flap, a cam disc is arranged, on the circumference of which a lever rests, which is connected in a rotationally fixed manner to the shaft of the second flap.

A valve includes a valve body provided with a plug, connected to an actuation system, an upstream duct, a downstream duct, and a purge duct provided with a shutter. The plug is movable in rotation about a longitudinal axis in the valve body, so that the rotation of the plug according to a first angular sector defines a flow between the upstream duct and the downstream duct, the rotation of the plug according to a second angular sector separate from the first angular sector shuts off the connection between the upstream duct and the downstream duct, and the rotation of the plug according to a third angular sector included in the second angular sector actuates the shutter so as to allow a flow from the upstream duct to the purge duct.

A valve, comprising: a housing, a holder, a first valve body, a bearing, and a second valve body. The housing comprises a first housing part, a second housing part, and a neck connecting the first housing part and the second housing part, a first valve body cavity is formed in the first housing part. The holder is provided in the second housing part, the holder and the second housing part together form a second valve body cavity and a pump cavity, the holder and the neck together form a bearing accommodating part for enabling the first valve body cavity to be in fluid communication with the pump cavity. At the bearing accommodating part defined by the holder and the neck, a limiter is provided, the limiter extends towards the bearing, the bearing has a receiving part, and the limiter cooperates with the receiving part to restrict movement of the bearing.

Apparatus and associated methods relate to a valve having an actuator configured to translate a mass in a plane and a valve element located out of the first plane and configured to translate along a first linear axis. In an illustrative example, at least one of the mass and the valve element may include a magnetic source providing a persistent magnetic field and the other may include a non-magnetized, magnetically permeable mass. Reluctance-induced forces may, for example, translate the valve element towards the mass along the first linear axis when the mass is brought into register with a second linear axis. The first linear axis and the second linear axis may, for example, be colinear. Various embodiments may advantageously provide a valve requiring low energy input for operation.
