摘要： PURPOSE:To keep a discharge rate constant by fitting a partition piston independently on a pressurizing piston to a shringe while forming a pressurizing chamber in respect to the pressurizing piston, making the partition piston descend interlockingly with the pressurizing piston, and keeping capacity of the pressurizing chamber constant irrespective of the position of the pressurizing piston. CONSTITUTION:A pressurizing piston 13 and a partition piston 27 are fitted into a shringe 12, while a pressurizing chamber 28 is formed in respect to the pressurizing piston 13. A constant rate of pressurized air is introduced into the pressurizing chamber 28 through an air pipe 25 from a control air supply device 37, and descends inside the pressurizing piston 13. Liquid agent 11 is dropped from a nozzle 12. The partition piston 27 keeps its stopping position by the operation of a unidirectional valve 35 of a control piston integrated with the partition piston 27. In the next cycle, air is intaken from the air pipe 25 by the control air supply device 37, and negative pressure is generated inside the pressurizing chamber 28. At this time, the pressurizing piston 13 does not ascend by surface tension of the liquid agent 11, while the partition piston 27 descends. Capacity of the pressurizing chamber 28 is kept constant.

When the solenoid 13 is electrified, the valve bodies 16 and 17 are attracted, and the valve body 16 closes a pressure introduction port 20 and opens an exhaust port E1, and the valve body 17 closes an exhaust port E2 and opens a pressure introduction port 21. Accordingly, the conversion chamber 15 turns to the high pressure side and the conversion chamber 14 to the low pressure side, and pressure fluid is introduced to a pressure chamber C2 and a pressure chamber C1 turns to release air and a piston P moves to the left.

摘要： PURPOSE:To obtain a switching valve having no residence of a fluid by holding a diaphragm at the opening of the upper part of a valve body and approaching and separating it to and from the inner face of a passage by an actuator from the external part. CONSTITUTION:A circular opening and closing mechanism hole 15 is formed at the center upper part of the valve body 11 having an inlet port passage 12, outlet port passage 13 and the liaison passage 14 communicating these. The peripheral edge of a diaphragm 18 is held by being interposed in the space with an actuator case 19 on the peripheral edge of the opening and closing mechanism hole 15. A truncated conical connection part 18b for connecting to the piston 20 of an actuator is formed at the center part of the diaphragm 18. A switching valve works by approaching and separating the diaphragm 18 to and from the valve seat face 14b of the liaison passage 14 by vertically moving the piston 20. A fluid is not stagnated due to no protruding body existing in the passage 14.

摘要： PURPOSE:To obtain a valve with a simple structure, having no sliding part and which can securely switch over a flow passage by supporting both ends of a valve stem with diaphragms and keeping the valve stem in a noncontact condition with a valve bore. CONSTITUTION:A valve bore 14 is provided in a center housing 12. And, diaphragms 15, 16 whose pressure receiving areas are not changed even if they are displaced are spread between the center housing 12 and both right and left side housings 13, 13 respectively. A normal-use port 22 is connected to right and left pressure chambers 17, 18 through a flow passage 23. Also, alternative ports 25, 26 are connected and opened to the valve bore 14. Valve parts 35, 36 are formed on the diaphragms 15, 16 being opposite to each valve seat 14b, 14c on both ends of the valve bore 14 and the valve parts 35, 36 are linked to each other with a valve stem 40. In this structure, the valve stem 40 is moved right and left by means of a plunger 52 to switch over the normal-use port 22 to either of the alternative ports 25, 26.

摘要： PURPOSE:To reliably switch a passage with a simple valve structure by supporting both ends of a valve stem on diaphragms and maintaining a noncontact state with a valve hole. CONSTITUTION:Peripheries of diaphragms 31, 32 are pinched between a center housing 12 and the right and left side housings 13, and both ends of a valve stem 25 are fixed to the center sections of the diaphragms 31, 32 respectively. The valve stem 25 is inserted into a valve hole 14 in a noncontact state, and a valve body 26 made of elastic body is coupled at its center section. The valve stem 25 is invariably moved and energized to the left by a compression spring 40. When a solenoid 41 is energized, a plunger 42 is protruded to push the valve stem 25 to the right.
