An electromagnetically actuated valve. The electromagnetically actuated valve with a small longitudinal extension, allows great through-flow quantities for the fluid with a small pressure difference. It is intended in this case that it should be producible cost-effectively in large unit numbers. An armature carries a plurality of valve bodies arranged in a point-symmetrical manner which together form a movable valve, wherein the plurality of valve bodies interact with a same plurality of valve seats which together form a stationary valve. The valve can be used along with a pump, a tank and/or other fluid units in assemblies for conveying mixtures of gas and liquid.

A valve cartridge includes a valve body that defines a hot water port that has a first end and a second end. The valve body includes a cold water port that has a first end and a second end. The valve cartridge includes a rotatable control stem that is disposed at least partially within the valve body. The valve body includes a main flow control disc that is coupled to the control stem. The main flow control disc has a cold water opening and a hot water opening. The valve cartridge includes a first auxiliary disc positioned between the first end of the hot water port and the main flow control disc and a second auxiliary disc positioned between the first end of the cold water port and the main flow control disc.

A technique facilitates drilling of wellbores with a steerable system having a plurality of pads which may be selectively actuated in a lateral direction to apply a side force. Application of the side force is used to steer a drill bit. A valve system is positioned to control delivery of actuating fluid under pressure to individual pads in a manner that enables steering of the drill bit. The valve system allows drilling along a desired curve by controlling the flow of actuating fluid under pressure to specific steering pads at specific angular positions. The valve system also allows drilling along a desired trajectory by preventing exposure of the pads to the pressurized actuating fluid.

A precision ceramics control balance valve includes a valve housing, a rotary base mounted in the valve housing, a slide mounted in the valve housing and located under the rotary base, a valve lever pivotally mounted in the rotary base and having an upper end protruding from the valve housing and a second end provided with a drive portion connected with the slide, a movable valve plate mounted in the valve housing and located under the slide, a fixed valve plate mounted in the valve housing and located under the movable valve plate, a valve seat mounted on the valve housing to stop the fixed valve plate, the movable valve plate, the slide and the rotary base, a temperature limiting device mounted in the valve seat, a pedestal connected with the valve seat, and a balance unit mounted in the pedestal.

A refrigeration system including a condenser; a (single) linear compressor that is activated and deactivated by a pulse width modulation switching device; a pulse width modulation refrigerant flow switch; at least two evaporators operably connected in parallel with one another with at least one evaporator associated with the refrigerator compartment that operates at a first refrigerant fluid pressure and with at least one other evaporator associated with the freezer compartment that operates at a second refrigerant fluid pressure; and a plurality of refrigerant fluid conduits operably connecting the condenser, the linear compressor and the evaporators into a refrigerant fluid flow circuit and such that the evaporators are capable of running simultaneously at different pressure levels and refrigerant flows from the evaporators, to the pulse width modulation refrigerant flow switch and through the pulse width modulation refrigerant flow switch.

The application relates to a valve device, including a valve housing which has at least three connection openings, each of which open into a chamber of the valve device, including two sealing disc units arranged at a distance from each other, each of which lies between two adjacent chambers and has a fixed sealing disc and at least one rotatable sealing disc, wherein each of the rotatable sealing discs and the fixed sealing discs of each sealing disc unit has at least one throughflow opening in order, in at least one overlapping position of the throughflow openings, to release a throughflow cross-section between the adjacent chambers, and including an actuating shaft, which is connected to the rotatable sealing discs for conjoint rotation.

The present invention provides a control valve for a water channel, which comprises of, from top to bottom, a control shaft bolt, a sliding valve disc, a fixing valve disc and a valve base. A valve shell combining with the valve base covers around a lower portion of the control shaft bolt, the sliding valve disc and the fixing valve disc to prevent mentioned components from falling out. The amount and the open/close operation of the two different kinds of water sources can be operated and controlled by a single control valve of the water channel to simplify the complexity in structure. Also it is convenient for a user to control the amount and the open/close operation of two different water sources by a single control valve.
