An integrated valve and manifold assembly includes a water valve configured to control water flow from one or two valve outlets. At least one of the outlets is coupled to a manifold. In some examples, the manifold is a dual-extrusion manifold having at least one air channel and at least one water conduit, and the water valve has a pair of air channels attached to a periphery of the water valve and configured to couple to the manifold air channels. In examples wherein at least one of the manifolds is a dual-extrusion manifold, a top portion of the assembly includes an air valve configured to control flow of air to air channel(s) of the dual-extrusion manifold. In other examples, the assembly includes a one-outlet or two-outlet water valve configured to couple to water manifolds, with no attached air channels or air valves.

The flow path switching valve includes (a) a valve body having an open flow path which opens on a predetermined surface over a predetermined length in a predetermined direction, (b) a main body having a plurality of ports which open on a facing surface facing the predetermined surface at an interval shorter than the predetermined length in the predetermined direction, and a plurality of connection flow paths connected to the plurality of ports, (c) plate springs attached on both ends of the valve body in the predetermined direction so as to support the valve body such that a predetermined gap is formed between the predetermined surface and the facing surface, the plate springs applying elastic force onto the valve body according to a movement amount of the valve body in the predetermined direction, and (d) an actuator which drives the valve body back and forth in the predetermined direction.

A shear seal includes a seal plate having a first seal surface and a sliding seal assembly having a second seal surface, and at least one of the first and second sealing surfaces comprise an insert comprising a material different than that of the seal plate or the sliding seal connected to the seal plate or sliding seal assembly by a compressed member disposed between the insert and the adjacent surface of seal plate or sliding seal assembly.

The disclosure relates to a valve for a fuel system having a body with at least one inlet and one outlet, the inlet fluidly connected to a pressurised fuel source in use. A shuttle is mounted within the body, the shuttle having a cavity of fixed volume and movable between a first position where fluid is permitted to flow through the inlet and is prevented from flowing through the outlet and a second position where fluid is prevented from flowing through the inlet and is permitted to flow through the outlet. A piston is configured to engage the fluid within the shuttle cavity to move the shuttle between the first and second position. A biasing mechanism biases the shuttle towards the first position and where the shuttle moves towards the second position when the fluid within the shuttle reaches a critical pressure.

Certain embodiments described herein are directed to manifolds that comprise a moveable, internal sealing member that can be used to engage one or more ports of the manifold and prevent or reduce fluid flow from the engaged port into the manifold. In certain examples, the manifold can be used in a mass spectrometer to control fluid flow from an interface and a turbomolecular pump.

A device for mixing and metering of at least two gases, comprising two bodies that can be displaced relative to each other, wherein margins of the bodies are in contact with one another and between these margins at least two rectangular openings for one gas each can be formed, wherein a displacement of the bodies relative to each other automatically causes an increase of one opening and a decrease of the other opening, wherein the resulting total cross-section of the openings remains constantly the same here. Moreover, the device comprises a control element which is arranged adjacent to the two bodies and in contact therewith, wherein the control element can be translationally displaced in a continuous manner between a closed position and an open position in order to close or to open the openings.

A hydraulic control circuit component such as a valve is configured which sliding surfaces. At least one of the sliding surfaces is configured as a single crystal material, such as ruby or sapphire.

A device and method enable both an automated and a user controlled diversion of fluid flow from a first pathway to an alternate pathway. The automated method relies upon detection of an environmental quality, such as fluid temperature, fluid heat content, fluid viscosity, fluid chemical composition, flow rate, or other detectable parameter. Both the automated diversion and the user controlled diversion rely upon positioning of the piston relative to the two pathways. The piston defines an internal pathway and the position of the piston internal pathway determines whether fluid flows through the first pathway or the alternate pathway. A lever movably couples the piston to an actuator; in the automated method an actuator responsive to its environment moves the lever to reposition the piston. In the user controlled method an override is applied, preferably manually, to reposition the piston to cause the diversion from the first pathway to the alternate pathway.

According to an aspect, an inflatable penile prosthesis includes an inflatable member, a reservoir configured to hold fluid, and a pump assembly configured to facilitate a transfer of the fluid from the reservoir to the inflatable member when the prosthesis is in an inflation mode and facilitate a transfer of the fluid from the inflatable member to the reservoir when the prosthesis is in a deflation mode. The pump assembly includes a pump, a valve body having a first valve and a second valve, and a selection member defining a lumen, the selection member being movable from a first position to place the prosthesis in the inflation mode and a second position to place the prosthesis in the deflation mode.
