摘要： The present disclosure provides a high flow coefficient spool valve (50) through one or more changes in the flow path from a conventional spool valve. The body (56) of the spool valve includes spherically contoured internal grooves (68). The spool (58), slidably engaged inside the body (56), includes concave surfaces between seals (62) that is complementary to the spherically shaped internal grooves (68) of the body. The spherical shape of the body internal grooves (68) and/or concave shape of the spool allow more volume and more laminar flow therebetween, resulting in an increased flow coefficient and flow capacity. The body also is formed with transverse port windows in the port that contour into a bore of the body adjacent the spool. A choke volume in the flow is strategically designed in a parallel flow location rather than a perpendicular flow location to promote laminar flow and lessen turbulence to also increase the flow coefficient.

摘要： [Problem]
To improve durability of a hot and cold water mixing valve.
[Means to Solve the Problem]
The hot and cold water mixing valve having a cylindrical casing 1 is provided with a control valve member 2 which adjusts an opening/closing ratio between a hot water inlet a and a cold water inlet b, by balancing between loads applied by a biasing member 4 and an actuator 5, and cylindrical temperature adjusting means 8 and 9 which adjusts a position of the control valve member 2 when subjected to rotation by a user. In the temperature adjusting means 8 and 9, an upper surface 81 is formed at one end, a knob 82 is provided in the center of the upper surface 81, and a ring-shaped recess 83 is formed around the knob 82 at the upper surface 81. The temperature adjusting means 8 and 9 are arranged inside the casing 1 such that the knob 83 is inserted, coaxially with the casing 1, into the hole 12 which opens at one end of the casing 1. A spacer 100 which covers the recess 83 formed at the upper surface 81 is interposed and held between the upper surface 81 of the temperature adjusting means and one end of the casing 1.

摘要： A poppet valve includes an inlet port, a first outlet port, a second outlet port, a first exhaust port, a second exhaust port, and a spindle. A first poppet element and a second poppet element each float relative to the spindle. A first piston and a second piston are fixed relative to the spindle. The spindle moves from an initial centered closed position to a first actuated position or a second actuated position to direct air flowing from the inlet port to the first outlet port or the second outlet port, respectively. The initial centered closed position is located between the first actuated position and the second actuated position. A housing contains the spindle, the first poppet element, the second poppet element, the first piston and the second piston.

摘要： An object of the present invention is to provide a spool valve capable of suppressing an adverse effect on fluid pressure control due to a fluid pressure acting on a spool. A valve sleeve 210 includes an input port P10, an output port P21 which is disposed to be connected to a channel for output T2, a discharge port P30 and a lead-in port P22 which is disposed to be connected to the channel for output T2. The spool 220 is provided with a second land section 224 that blocks a portion between the spool 220 and the valve sleeve 210 at a position between the output port P21 and the lead-in port P22 when the spool 220 is located in a position for connecting the channel for input T1 and the channel for output T2 and blocking a channel leading from the channel for output T2 to the channel for discharge T3, and when the spool 220 is located in a position for connecting the channel for output T2 and the channel for discharge T3 and blocking a channel leading from the channel for input T1 to the channel for output T2.

摘要： The present invention discloses a reversing value (1000) which includes a pilot valve (1200) and a main valve (1100). The main valve (1100) includes: a valve body (10) with a valve chamber (20), wherein the valve chamber (20) is provided with a valve seat (30) therein, and the valve seat (30) is provided with a plurality of valve ports (40) thereon; a plurality of flow path ports (50) are correspondingly communicated with the plurality of valve ports (40); a sliding valve core (60) matching the valve seat (30). The plurality of valve ports (40) include a first valve port (41), a second valve port (42), a third valve port (43), a fourth valve port (44), and a fifth valve port (45). The plurality of flow path ports (50) include an S port (S), an E port (E), a C port (C), a D1 port (D1), and a D2 port (D2). When the sliding valve core (60) slides to a first preset position, the D1 port (D1) is communicated with the E port (E), and the S port (S) is communicated with the C port (C). When the sliding valve core (60) slides to a second preset position, the D2 port (D2) is communicated with the C port (C), and the S port (S) is communicated with the E port (E). The present invention also discloses a cooling system with the reversing valve (1000). The reversing valve (1000) can effectively solve the problem in the prior art that the pressure of high pressure fluid in a valve chamber of a reversing valve is unstable in the switching process.
