Abstract: A gate valve assembly includes a valve seat and a valve. The valve seat includes a passage opening and a contacting region surrounding the passage opening. The valve includes a groove located on a marginal region of the valve, and a sealing body positioned in the groove. The passage opening is closed by covering the valve over the valve seat, and an upper surface of the sealing body is tightly contacted with the contacting region. Therefore, the valve is prevented from rubbing against the valve seat and producing particles.

Abstract: An ortho-planar spring has a platform (14) movably coupled to a base (10) and being movable linearly with respect to the base along at least a portion of an axial direction (22) perpendicular to both a base surface and a platform surface. A resilient and flexible connecting structure (18) is connected to and between the base and platform. The connecting structure is bendable to develop (i) an axial force along the axial direction to bias the platform in a stable position with respect to the base, and (ii) non-axial forces which substantially sum to zero to preserve the orientation of the platform with respect to the base. Thus, the spring is very compact and does not have rotation between the deflecting ends. The spring may be associated with a valve opening (213), and a button (214) for restricting flow through the valve opening, to bias the button at a position with respect to the valve opening.

Abstract: A valve assembly has a valve body with a bore formed therein. A valve spool is slidably disposed in the valve body. The valve spool has a plurality of valve lands that closely engage the valve bore to form substantially leak-free interfaces. The leading land has a diameter less than the land immediately adjacent thereto in a range of 0.34 mm to 0.17 mm, and a recess formed between the leading land and the first adjacent land. The recess has an inner diameter at least 0.75 mm less than said diameter of said leading land.

Abstract: An integrated pneumatic manifold for installations that require electrical and other components to be separated from a harmful or dangerous environment, in which pneumatic (and/or hydraulic) devices operate, the manifold comprising a block that has drilled into it a large number of passages that are directed in various directions and located at various levels, some passages crossing partially and some wholly with others and cavities machined in various positions. The block has mounting points for components on its surfaces and passive and active pneumatic components are integrated into the cavities and passages of the block. The block serves as a separation between the safe and harmful environments and as a substitution for many passive and active pneumatic components that would normally be individually connected.
