A flow path switching valve includes (a) a valve body in a shape of a rectangular parallelepiped having a predetermined surface and an opposite surface, the valve body including an open flow passage having an opening on the predetermined surface, (b) a main body including a plurality of ports having a respective opening on a facing surface thereof facing the predetermined surface, and a plurality of connection flow passages each connected to respective one of the plurality of ports, (c) a pair of plate springs attached to opposite ends of the valve body to support the valve body with a predetermined gap formed between the predetermined surface and the facing surface, the plate springs applying elastic force to the valve body in accordance with an amount of movement of the valve body in a predetermined direction, and (d) an actuator for reciprocating the valve body in the predetermined direction.

The flow path switching valve includes (a) a valve body having an open flow path which opens on a predetermined surface over a predetermined length in a predetermined direction, (b) a main body having a plurality of ports which open on a facing surface facing the predetermined surface at an interval shorter than the predetermined length in the predetermined direction, and a plurality of connection flow paths connected to the plurality of ports, (c) plate springs attached on both ends of the valve body in the predetermined direction so as to support the valve body such that a predetermined gap is formed between the predetermined surface and the facing surface, the plate springs applying elastic force onto the valve body according to a movement amount of the valve body in the predetermined direction, and (d) an actuator which drives the valve body back and forth in the predetermined direction.

A valve, comprising a housing with an inlet and an outlet, a closure, which is displaceable between a first position and a second position, wherein in the first position, a flow path from the inlet to the outlet is formed or interrupted, and wherein the flow path is interrupted or formed in the second position, and an actuation unit having a coil and an armature. The armature displaces the closure between the two positions subject to a current applied to the coil, wherein the armature has a cone, wherein a force on the armature is modifiable via an ascent of the cone.

A flow rate ratio control valve includes a pair of plate springs, each of which applies elastic force in a predetermined direction in accordance with the amount of deformation, a valve body supported by the pair of plate springs to be movable in the predetermined direction, a drive unit which drives the valve body in the predetermined direction in a non-contact state by means of electromagnetic force applied to a region between the pair of plate springs in the predetermined direction, a container in which the plate springs and the valve body are contained, and a damper which is attached to the valve body, defines a sectioned predetermined space in cooperation with an inner surface of the container, and forms a predetermined gap between the damper and the inner surface, the predetermined gap establishing communication in the predetermined direction between the predetermined space and the exterior of the predetermined space.

A valve operating member includes a valve support portion, which supports a valve disk while allowing the valve disk to move relative to the valve operating member in a direction of an axis. An elastic member is disposed inside a valve chest. The elastic member constantly urges the valve disk toward the valve seat in the direction of the axis to cause the valve disk to be seated on the valve seat with an urging force. The valve support portion includes a valve engagement portion, which is engaged with an engaged portion of the valve disk seated on the valve seat, and separates the valve disk apart from the valve seat. When the valve disk is seated on the valve seat, the valve engagement portion is not in contact with the valve disk in the direction of the axis.

A fluid delivery device includes a tube coupled to an axial manipulator. The axial manipulator includes an elongate member arranged to move axially in a housing. The tube is in fluid communication with a fluid diverter which is arranged to move axially in the housing upon axial movement of the elongate member. Seals are provided to prevent fluid from leaking out of the housing. A fluid port is in fluid communication with the tube via the fluid diverter, such that fluid can flow in and out of the tube via the fluid port and the fluid diverter.

A pilot valve is provided, which comprises a valve body having a cylindrical structure, a magnetically permeable sleeve made of permeability magnetic material, and a coil assembly. The magnetically permeable sleeve is sleeved and fixed on one end of the valve body. The coil assembly is sleeved on the magnetically permeable sleeve. The coil assembly comprises an electromagnetic coil wound along the circumference of the magnetically permeable sleeve.

A valve operating member includes a valve support portion, which supports a valve disk while allowing the valve disk to move relative to the valve operating member in a direction of an axis. An elastic member is disposed inside a valve chest. The elastic member constantly urges the valve disk toward the valve seat in the direction of the axis to cause the valve disk to be seated on the valve seat with an urging force. The valve support portion includes a valve engagement portion, which is engaged with an engaged portion of the valve disk seated on the valve seat, and separates the valve disk apart from the valve seat. When the valve disk is seated on the valve seat, the valve engagement portion is not in contact with the valve disk in the direction of the axis.
