A fluid valve device. A first rotary slide valve, a second rotary slide valve, and a servomotor are provided. Each of the rotary valves has a rotary slide arranged in a rotary slide housing and drivable via a drive shaft by the servomotor. The first rotary slide valve is rigidly coupled and the second rotary slide valve is coupled via a freewheel to the drive shaft.

A multi-level rotor for a coolant flow control valve assembly, which accommodates an increased number of inlet ports, outlet ports, and flow channels using a single rotor located in a housing, enabling a larger number of flow configurations. The housing includes nine ports which may function as an inlet or an outlet, which facilitates different flow configurations. For a thermal management system, reduced cost and less space utilization is achieved by a reduced number of valves, where the multi-level rotor is able to fluidically connect multiple inlets/outlets. This enables different flow configurations, depending on the degree of rotation. The channels at different levels are sealed from each other within the housing. The flow channels are manufactured into a single entity, therefore always having the same positional accuracy relative to each other when the rotor is repositioned.

A suction/irrigation medical device comprises a valve body having one or more conduits fluidically coupled thereto and a first channel extending through the valve body. The medical device also comprises a first valve plunger disposed along the first channel and configured to move along an axis to open and close the first channel. The first valve plunger has a first opening to permit a fluid to flow through the first channel. The medical device also comprises a second valve plunger disposed along the first channel and along a second channel to couple the second channel into the first channel when the second valve plunger is in a first position. The second valve plunger has a second opening that has at least one dimension that is greater than a corresponding dimension of the first opening of the first valve plunger.

A fluid control valve includes a valve assembly having a ring gear, an array of first rotary valve bodies, an array of second rotary valve bodies, and a sealing plate. Each of the first rotary valve bodies includes at least one first flow path formed therethrough and each of the second rotary valve bodies includes at least one second flow path formed therethrough. The sealing plate includes a plurality of flow openings formed axially therethrough with each of the flow openings configured to provide fluid communication between one of the first flow paths of the array of first rotary valve bodies and one of the second flow paths of the array of second rotary valve bodies. Rotation of the ring gear causes selective rotation of the first and second rotary valve bodies to alter the flow configuration present between the arrays of the first and second rotary valve bodies.

A multi-tubing pinch valve assembly including a receiving space defined between a pinch protrusion and tubing contact body. The multi-tubing pinch valve assembly is moveable between a retracted state and an extended state. In the extended state, multiple tubes disposed in the receiving space are pinched, restricting flow therethrough. In the retracted state, multiple tubes are capable of being loaded into and/or out of the receiving space.

A double 6-way valve for a vehicle cooling system provides various modes, reduces the number of parts of the cooling system, and improves packaging, compared to a conventional cooling system. The double 6-way valve includes: an upper housing including a plurality of upper nipples disposed at equal intervals on an outer circumference surface thereof; a lower housing stacked under the upper housing and including a plurality of lower nipples disposed at equal intervals on an outer circumference surface thereof; an upper hub rotatably mounted within the upper housing; a lower hub rotatably mounted within the lower housing and stacked under the upper hub; and a driving apparatus to rotate the upper hub and the lower hub.

The air valve includes a supply valve configured to open and close an air supply passage through which the air gas to be supplied to the fuel cell stack from outside flows; a switching valve configured to switch between a state in which the air gas supplied from the outside flows through the air supply passage and a state in which the air gas supplied from the outside flows through a bypass passage that branches from the air supply passage; and a link mechanism connected to the supply valve and the switching valve and configured to actuate the supply valve and the switching valve. The link mechanism includes an arm portion fixed at the supply valve; and a cam plate fixed at the switching valve, wherein the cam plate includes a guide portion with which the arm portion is to contact.

A double-power-supply complex control device includes a main body. Four control sections and two load flow ways are disposed in the main body. A main flow way is disposed in control section. Four switch members of a switch assembly are assembled and disposed in the main flow ways. A circumference of each main flow way is in communication with multiple bypasses. The main flow ways of each two of the control sections are in communication with a fluid output passage and a fluid input passage of a power device. Some of the bypasses of control section are in communication with each other. A lower flow guide window is disposed on switch member in indirect communication with main flow way. When switch member is operated under external force, the lower flow guide window is switchable between the bypasses to selectively communicate with the bypasses to make different power devices drive.

A suction/irrigation medical device comprises a valve body having one or more conduits fluidically coupled thereto and a first channel extending through the valve body. The medical device also comprises a first valve plunger disposed along the first channel and configured to move along an axis to open and close the first channel. The first valve plunger has a first opening to permit a fluid to flow through the first channel. The medical device also comprises a second valve plunger disposed along the first channel and along a second channel to couple the second channel into the first channel when the second valve plunger is in a first position. The second valve plunger has a second opening that has at least one dimension that is greater than a corresponding dimension of the first opening of the first valve plunger.

A valve apparatus is provided for controlling the flow of fluids in two temperature control circuits and includes an actuator, a valve housing with a first receiving chamber and a second receiving chamber, a direct ball valve having the first receiving chamber with at least a first and a second fluid port, wherein a first ball device with a first passageway is rotatably mounted in the first receiving chamber, wherein the first ball device is coupled to the actuator and is directly actuatable by the actuator, and an indirect ball valve having the second receiving chamber with at least a third and a fourth fluid port, wherein in the second receiving chamber a second ball device with a second passageway is rotatably mounted, wherein the second ball device is coupled to the first ball device and is thus actuatable by the direct ball valve and indirectly actuatable by the actuator.
