A linear compressor includes a discharge valve detachably attached to a front end surface of a cylinder to open and close a compression space of the cylinder; and a valve spring elastically supporting a rear surface of the discharge valve to press the discharge valve toward the front end surface of the cylinder. The discharge valve includes reinforced fiber, and the reinforced fiber is arranged parallel to the front end surface of the cylinder. Accordingly, while a rigidity of the discharge valve is improved, a weight of the valve is reduced to enhance responsiveness of the valve, suppress abrasion of the cylinder, and reduce striking sound.

A serviceable valve carousel system may include a valve carousel housing having a valve carousel receiver, a valve service port, an integrated first port adapter, and an integrated second port adapter. A rotatable valve carousel may be rotatably disposed within the valve carousel housing. The rotatable valve carousel may include a substantially cylindrical portion, a removable valve lumen, a valve cap receiver, and a removable valve cap having a substantially radiused portion compatible with a substantially radiused portion of the substantially cylindrical portion of the rotatable valve carousel. The rotatable valve carousel is rotatable between a first state that allows fluid communication through a removable valve at least partially disposed within the removable valve lumen and a second state that allows the removable valve cap and removable valve to be removed and replaced via the valve service port without use of tools while maintaining a sewage connection.

A device for limiting or keeping constant a quantity of fluid flowing therethrough, includes: a housing with a front chamber and a rear chamber; a partition arranged in the housing with two or more openings; and a flow limiting element arranged in one or both openings. The flow limiting element includes a housing provided with an inlet, an outlet and a throughflow opening; and a resilient plate-like valve element mounted in the housing, substantially able to close the throughflow opening by resilient movement in the direction of a valve seat arranged in the housing adjacently of the throughflow opening. The valve element is fixed on one side and can move resiliently on the opposite side in the direction of the valve seat. A mould produces one or more injection-moulded products. The injection-moulded product is a flow limiter for limiting the force of the flow of a fluid flowing therethrough.

A dental valve device has a valve body having a tip receiving end having a flexible tubing extending outwardly from the tip receiving end with the flexible tubing having a flexible tubing opening, a hose receiving end, a lumen formed between the flexible tubing opening and the hose receiving end, and a partial opening formed in the valve body, and a rotatable valve sealing body adapted to be inserted into the partial opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the flexible tubing opening and the hose receiving end, the bore having a tip receiving opening and a hose receiving opening.

A check valve includes an upper housing defining an inlet of the check valve, and a lower housing having a seating portion and defining an outlet of the check valve. The check valve further includes a chamber interposed between and defined by the upper and lower housings for fluidly connecting the inlet and the outlet, and a flexible diaphragm mounted in the chamber. The flexible diaphragm selectively permits fluid flow in a first direction, and prevents fluid backflow in a second direction opposite to the first direction. The flexible diaphragm includes a color changing material, and when the flexible diaphragm is seated on the seating portion and bent due to force of the fluid flowing in the first direction, the flexible diaphragm exhibits a color change.

A branching tool serving as a check valve incorporated in a cleaner device includes: a main unit provided with an inflow channel and a first outflow channel; a sealing member that allows a flow of cleaning fluid from the inflow channel to the first outflow channel when the cleaner device is in operation and that is formed to seal a backflow of the cleaning fluid from the first outflow channel to the inflow channel when the cleaner device is not in operation; and a lid member that is combined with the main unit so as to form a housing chamber for the sealing member. The lid member has a communication hole that allows the housing chamber to communicate with the outside. The lid member or the main unit is provided with a water receiving recess arranged around the communication hole.

A thin profile gas transporting device includes a gas collecting plate, a valve sheet, a discharge sheet, and a gas pump. The gas pump is disposed on the gas collecting plate. The gas collecting plate, the valve sheet, and the discharge sheet are stacked and assembled sequentially. Through simplifying the structures of the gas collecting plate and the discharge sheet, the thicknesses of the gas collecting plate and the discharge sheet can be reduced. Moreover, through the arrangement of several pressure relief holes, the pressure relieving operation can be performed rapidly and quietly.

A fluid control apparatus includes a piezoelectric pump and valve. The valve includes a second valve housing, second seal member, diaphragm, first seal member, and first valve housing and has a structure in which they are laminated in sequence. The first valve housing includes a second vent and third vent, has a valve seat, and includes six cavities. The second valve housing has a first vent and first vent and includes a valve seat and six first protrusions. The second valve housing further includes six second protrusions nearer the outer edges than the six first protrusions, as seen in the x-axis direction in plan view.

An assembly is provided that comprises at least one valve unit (20, 30) comprising a plurality of valves (25), the at least one valve unit (20, 30) having a plurality of valve unit protrusions (32) extending in a first direction and at least one valve unit fastener-engaging component (36); a valve control block (10) configured to open and close the plurality of valves (25), the valve control block (10) comprising a plurality of pins (15) extending in the first direction (A); and at least one thrust plate (40) comprising a plurality of thrust plate protrusions (42), a plurality of thrust plate apertures (44) configured to receive the plurality of pins (15) and at least one thrust plate fastener-engaging component (46);
