Abstract: A vacuum control valve connected between a vacuum chamber and a vacuum pump includes a control valve main body having a valve seat formed in a vacuum flow passage, a valve body that manipulates the valve opening by performing a linear motion to adjust a lift, a rod that transmits driving force from a linear driving unit that generates the driving force, a sliding/sealing member that seals the vacuum flow passage while allowing the rod to slide, and a cylindrical member that covers a sliding range of the rod. The sliding range includes a range movable from a valve body flow passage side to an exterior side. The cylindrical member has an outer peripheral surface, a working fluid absorption amount per unit area of the outer peripheral surface being smaller than that of an outer surface of the rod.

Abstract: A four-way valve includes a body and a valve component. The body includes a valve chamber and first to fourth communication channels which communicate with the valve chamber at positions arranged in sequence in a predefined rotational direction and cause the valve chamber to communicate with an outside. The valve component is rotatable in the predefined rotational direction and switches the four-way valve to be in at least one of: a first state in which the first and second communication channels communicate with the first region and the third and fourth communication channels communicate with the third region; and a second state in which the second communication channel communicates with the first region, the third communication channel communicates with the second region, and the first and fourth communication channels communicate with the third region.

Abstract: A chemical liquid circuit apparatus includes a main circuit member, a sub-circuit member, and a frame member. The main circuit member has a chemical liquid channel for flowing a chemical fluid, and a main opening formed on an end of the chemical liquid channel. The sub-circuit member is mounted on and in contact with the main circuit member and applies a first load to the main circuit member. The sub-circuit member has a sealing surface for sealing the main opening from outside of the apparatus. The frame member has a storing portion for storing the main circuit member, and a connecting opening disposed in a position in communication with the main opening of the main circuit member stored in the storing portion. The shape of the frame member allows a reaction force of the first load to be transferred from the storing portion to the main circuit member.
