摘要： PROBLEM TO BE SOLVED: To provide a work condition changeover device capable of properly maintaining the neutral condition of a member to be controlled. SOLUTION: The work condition changeover device 10 turns a link 33 communicated with the member to be controlled in either one-side direction or the other-side direction and selectively switches the neutral condition to a first work condition or a second work condition. The work condition changeover device 10 is integrally mounted to the link 33 and a body stopper 44 fixed to a valve housing 31, and comprises a link stopper 46 for setting the neutral condition of the member to be controlled by being positioned in the peripheral direction corresponding to the body stopper 44, and a torsion spring 34 disposed on almost the same coaxis of the link 33 and fixed while keeping a predetermined energizing force so as to position the link stopper 46 in the peripheral direction corresponding to the body stopper 44. The neutral condition of the member to be controlled is set by positioning the link stopper 46 in the peripheral direction by the predetermined energizing force using the torsion spring 34 corresponding to the body stopper 44.

摘要： PURPOSE: To restrain partial abrasion on the tip of a valve stem, so as to improve the life of the valve stem by enabling the relative movement between a first moving member to be brought in contact with a cam and a second moving member to be brought in contact with the stem tip to be regulated. CONSTITUTION: Oil pressure in an oil pan 38 is supplied into an oil pressure chamber 37 by an oil pressure pump 39 through oil pressure passage 41, a groove 42, and a passage 43. As a result, a plate 34 is moved toward the first position from the second position against an energizing force of a spring 45, and the plate is partially formed on a slider 32 and advanced into an annular groove 321. And the plate 34 stops in the first position by the small diameter part of the slider main body part 322. Thereby, the relative movement between the slider 32 and the plate 34, namely, between an outer body 21 and inner bodies 24, 25, is prevented. Since the contact of the tip of a stem 14 with the plate 34 is avoided, partial abrasion on the tip of the stem 14 can be restrained, and the life of the stem 14 is improved.

摘要： PROBLEM TO BE SOLVED: To provide a two stage actuator with an easy structure. SOLUTION: A first actuator 11 has a negative pressure chamber 31 and an atmosphere chamber 32 divided by a diaphragm 22. The diaphragm 22 is joined to an activating rod 24. A second actuator 12 can form a pressure sensing chamber 52 communicating to an negative pressure chamber 51 and an negative pressure chamber 31 because a built-in middle stopper 42 is set onto a bottom wall. When negative pressure is developed into only the negative pressure 31, the activating rod 24 is lifted. Furthermore, the activating rod 24 is regulated to move in a given range by the stopper shaft 42b of the middle stopper 42 that is pressed to the bottom wall because of the difference pressure between the negative pressure chamber 51 and the pressure sensing chamber 52, and thereby, the activating rod 24 makes a first stage stroke. When negative pressure is developed into the negative chamber 31 and an inner space 50, the activating rod 24 is further lifted with the middle stopper 42 together via the stopper shaft 42b, and thereby makes a second stroke.

摘要： PROBLEM TO BE SOLVED: To effectively generate a circulating vortex current of a swirl, a tumble or the like with a simple and inexpensive structure by comprising a port for introducing the supercharged pressure by a supercharger to a combustion chamber of an engine, and another port for introducing the atmospheric air from a throttle valve by the intake negative pressure to the combustion chamber. SOLUTION: When an engine is started and a piston is in an intake stroke, a negative pressure is applied to a combustion chamber 2, and the air corresponding to the opening and closing amount of a throttle valve 5 is introduced into the combustion chamber 2 through one of ports 4 forming an intake port 12. Simultaneously the supercharged pressure is introduced into the combustion chamber 2 from a supercharger 1 through the other port 3. On this occasion, the pressure of the air introduced from the port 3 is higher than that of the air introduced from the port 4, and a large amount of the air is introduced from the port 3, so that the circulating vortex current of the air can be effectively generated in the combustion chamber 2 by this difference. Whereby the circulating vortex current can be obtained in the whole rotational frequency zone of the engine without curving the ports 3, 4 into the complex shape.

CONSTITUTION:A flow rate control valve is equipped with a first port 2 into which fluid flows; a second port 3 from which fluid flows out, a housing 1 in which an inner space 4 is housed; a buffer space 5 formed between the first port 2 and the inner space 4; a cover 9 disposed at one end of the buffer space 5; a valve means 6 which is disposed in the inner space 4 to communicate the first port 2 with the second port 3 and to cut off both of the ports 2, 3; and with a solenoid means 10 controlling the valve means 6. A filter 14 is housed in the second port 3. By this constitution, foreign matter such as oil, gasoline, carbon and the like hardly enter the flow rate control valve from the outside through the second port 3.
