Abstract: An electromagnetic valve includes a flow passage, a valve member, an actuator having a coil and a movable core, an intermediate member, a connecting member, a housing, and a dividing unit. The housing includes a hollow part between the housing and the actuator. The hollow part communicates with the flow passage. The dividing unit includes a through hole which passes through the dividing unit in its axial direction. The dividing unit divides the hollow part between a communicating chamber that is capable of communicating with the flow passage, and a cancel chamber that is cut off from an outside thereof. The intermediate member includes a communicating passage between the intermediate member and the movable core. The communicating passage communicates between the flow passage and the cancel chamber via the through hole and the communicating chamber.

Abstract: A two-stage electro-magnetic valve maintains a pressing force applied onto a switch valve body from a press member after a lifting of an open-close valve body from a valve seat by an introduction of a pressure of a valve chamber. In such manner, the switch valve body need not be put in a pressure receiving state when the switch valve body is completely closed. In other words, it is not necessary for a pressure receiving diameter of the switch valve body to be smaller than a pressure receiving diameter of the open-close valve body. Such configuration increases design freedom of the pressure receiving diameter for the open-close valve body because it separates the diameter of the valve body from a diameter restriction of the switching valve body, which allows both valve bodies to have the same diameter, which maximizes the effect of a pressure cancel mechanism.

Abstract: A stator is located in a coil. A movable body is attracted toward the stator when the stator is magnetized by the coil. A valve element is movable integrally with the movable body to open and close a fluid passage when the coil is activated and de-activated. A regulating member is opposed to the movable body to regulate movement of the movable body. An elastic member is equipped to one of the regulating member and the movable body and is elastically deformable between the movable body and the regulating member when the movable body is attracted toward the stator. The elastic member is located at a position shifted in a radial direction relative to the regulating member or the movable body. The elastic member is in an asymmetrical shape relative to an axial rotational direction.

Abstract: A two-stage changeover valve is provided in a vaporized fuel passage connected between a fuel tank and a canister. A valve member is movably accommodated in a fluid passage formed in a valve housing. A valve seat is formed at an inner peripheral wall of the valve housing, so that the valve member is operatively seated on the valve seat. A restricted communication hole is formed in the valve member, so that an upstream side and a downstream side of the valve member are communicated with each other, even when the valve member is seated on the valve seat. The restricted communication hole is formed in a Laval-nozzle shape, so that vaporized fuel passing through the restricted communication hole is accelerated. As a result, a process for depressurizing inner pressure of the vaporized fuel in the fuel tank can be carried out in a shorter time.

Abstract: A first hole is connected through a first fluid chamber to an inflow hole. A first valve seat is formed around the first hole. A second fluid chamber is connected through a second hole to the first hole. An outflow hole is connected to the second fluid chamber. A second valve seat is formed around the second hole. A third valve seat is formed around the outflow hole. A first valve element is movable in the first fluid chamber to make contact with the first valve seat. A second valve element is movable in the second fluid chamber to make contact with the second valve seat or the third valve seat. A biasing member biases the second valve element toward the second valve seat. An outer peripheral passage is formed between an outer periphery of the second valve element and the second housing to enable flow therethrough.

Abstract: An internal pressure sensor detects an internal pressure of the fuel tank, which stores fuel. A solenoid valve is configured to close to seal the fuel tank and is configured to open to open the fuel tank. An internal pressure acquisition unit is configured to acquire an internal pressure of the fuel tank from the internal pressure sensor. A drive control unit is configured to control the solenoid valve to open when the internal pressure of the fuel tank is greater than or equal to a first predetermined value, which is a negative value, and is less than a second predetermined value, which is 0 or a positive value.

Abstract: An evaporative fuel processing device for determining a leak of an evaporation piping system also determined pump abnormality by including a pump, a pressure sensor and an abnormality determiner, i.e., by pressuring/de-pressuring the system to a positive/negative value against an atmospheric pressure for leak determination, by detecting a pressure of the system, and by determining a leak hole in a normal leak determination mode based on an absolute value of the detected pressure reaching or not reaching a target value after pump operation and based on an assumption that the pump is normal. Specifically, after lapse of a determination time from a pump stop, the absolute value equal to or less than a normal leak determination threshold value is determined that a leak hole is present in the system. Further, the absolute value not reaching the target value even after pump operation triggers a pump abnormality determination mode.

Abstract: A two-stage switch valve includes a valve body slidable in a flow passage of a fluid, and a spring urging the valve body upstream. The valve body includes a valve element slidable in the flow passage, an upstream guide having a ring shape and being slidable in the flow passage, and legs connecting the valve element and the upstream guide. The upstream guide is located upstream of the valve element. The legs are inclined from an axial direction of the upstream guide and extend from the upstream guide toward a center of the valve element.

Abstract: A valve device includes a valve seat forming member, a case, a first O-ring, and a second O-ring. The valve seat forming member is fit into a passage defining and forms a valve seat. The case houses an electromagnetic solenoid and is connected to the passage defining member. The first O-ring is interposed between an inner circumferential surface of the passage defining member and an outer circumferential surface of the valve seat forming member. The first O-ring prohibits the fluid from flowing through a space between the passage defining member and the valve seat forming member when the main valve body seats on the valve seat. The second O-ring is interposed between the case and the passage defining member. The second O-ring prohibits the fluid from flowing from the passage to an outside of the passage defining member.
