A two-input and two-output valve core structure comprises: a hood-shape outer shell, and a sway plate sleeve, a sway plate, a movable porcelain plate, and a fixed porcelain plate disposed therein. Wherein the hood-shape outer shell is provided with an upper passage port and a lower passage port. The movable porcelain plate includes a detachable upper movable plate and a detachable lower movable porcelain plate. The fixed porcelain plate includes a detachable upper fixed porcelain plate, a detachable lower fixed plate. A middle section of the sway plate is hinged onto the sway plate sleeve, an upper sway head of the sway plate is protruded out of the upper passage port of the hood-shape outer shell, while a lower sway head of the sway plate is extended into an upper opening of the upper movable plate.

A turbocharger system is disclosed, including a turbine and compressor and a rotary valve unit. The rotary valve unit comprises a fixed valve seat and a rotary valve member arranged coaxially with the valve seat. The valve member is disposed against the valve seat and is rotatable about the axis for selectively varying a degree of alignment between respective orifices in the valve seat and valve member. The valve unit includes a valve housing that defines a first flow passage and a second flow passage, and the valve member and valve seat are disposed in the second flow passage. A turbocharger system is also disclosed, including a turbine and compressor and the rotary valve unit. The rotary valve unit is coupled with the turbine such that exhaust gas that has passed through the turbine wheel is fed into the first flow passage of the rotary valve unit, and exhaust gas that has bypassed the turbine wheel is fed into the second flow passage of the rotary valve unit.

A grid valve may include an annular stationary plate having a first annular surface, and an annular rotatable plate disposed on the annular stationary plate and rotatable relative to the annular stationary plate. The annular rotatable plate may have a second annular surface, and each of the annular stationary plate and the annular rotatable plate may define a plurality of holes in the respective annular surfaces thereof. The grid valve may further include a first magnet disposed on the first annular surface and a second magnet disposed on the second annular surface such that the first magnet repels the second magnet.

A fluid circulation circuit includes a flow passage switching valve. The flow passage switching valve includes a body and a switcher. The body includes a first inlet, a second inlet, and outlets including a first outlet. The switcher is capable of switching a passage configuration to a state in which a fluid that has flowed in from the first inlet flows out of either one of the outlets and a state in which the fluid that has flowed in from the second inlet flows out of either one of the outlets.

Disclosed is a flow control valve 100. The flow control valve 100 comprises a cylindrical body 20, a piston 40, at least one fluid seal 60, a handle 60 and a nut 90. The flow control valve 100 is connected between an inlet and an outlet of a pipe to control flow of liquid/gases passing there through even at high temperature and pressure. The flow control valve 100 provides good force to the liquid/gas passing there through and provides an equal distribution of the flow at the outlet without resulting in pressure drop.

A rotary damper is provided. The rotary damper includes a first housing plate having a substantially flat substrate with a first plurality of windows; a rotary disc having a substantially flat substrate with a second plurality of windows, wherein the rotary disc is in rotatable communication with the first housing plate; and a motor that drives rotation of the rotary disc relative to the first housing plate such that the rotary disc rotates from a first configuration in which the second plurality of windows overlaps with the first plurality of windows of the first housing plate to at least a second configuration in which the second plurality of windows on the rotary disc and the first plurality of windows on the first housing plate do not overlap. Also provided is a refrigeration/freezer unit utilizing the rotary damper to control airflow between a freezer compartment and a refrigeration compartment.

Embodiments of the invention described herein thus provide improved flush valves that are designed with improved venting features and improved inlet designs. The described venting features and inlet designs, either alone or in combination, can help prevent ingestion of waste into the interior of the valve.
