As the inner housing is rotated at a predetermined interval by the driving unit, the first inlet is connected to one or both of the first outlet or the second outlet, the second inlet is connected to one of the third outlet or the fourth outlet, and the third inlet is connected to one or both of the fifth outlet and or the sixth outlet.

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 meter bar includes a housing comprising an inflow end and an outflow end, a key assembly arranged within housing, the key assembly including a key, the key defining an interior and providing a fluid pathway from the inflow end to the outflow end; the key defining a pair of upper portals, one upper portal proximate the inflow end and one upper portal proximate the outflow end; the key defining a pair of lower portals, one lower portal proximate the inflow end and one lower portal proximate the outflow end; the key defining a pair of bypass portals; the key assembly arrangeable within the housing to selectably direct fluid flow from the inflow end to the outflow end either through a meter or bypassing the meter.

A refrigerant control valve apparatus includes a valve body accommodated inside a valve housing, the valve housing being formed with an inlet port and a discharge port. A seal mechanism includes a seal body and a biasing mechanism. The seal mechanism is provided with a first pressure receiving surface receiving pressure of the refrigerant, which acts in a direction same as a biasing direction of the biasing mechanism, and a second pressure receiving surface receiving pressure of the refrigerant, which acts in a direction opposite to the biasing direction of the biasing mechanism. The first pressure receiving surface and the second first pressure receiving surface are formed to include an equal area to each other, and the seal mechanism is accommodated within a seal accommodation space such that pressure of the refrigerant from the inlet port acts on the first pressure receiving surface and the second pressure receiving surface.

A fluid injection system includes a valve device and a valve actuation device. The valve device has a valve member and a valve member coupling. The valve member has an open position that permits fluid to pass through and a closed position that prevents fluid from passing through. The valve member coupling is configured, when actuated, to transition the valve member between the open and closed positions. The valve actuation device having a valve actuation coupling and a drive mechanism. The valve actuation coupling is coupled to the valve member coupling and drive mechanism. The valve actuation coupling is movable independent of the drive mechanism to couple the valve actuation coupling to the valve member coupling. And, the valve actuation coupling is movable with the drive mechanism to actuate the valve member coupling to transition the valve member between the open and closed positions.
