Abstract:
PROBLEM TO BE SOLVED: To provide a technology capable of attaining synchronization even when a telegram including synchronizing information causes a transmission error by avoiding defects of prior arts and improving a synchronization method of a form mentioned at the beginning of the description. SOLUTION: Composite synchronizing information is formed from synchronizing information items of at least two telegrams and used for synchronizing a second participant with a central participant.

Abstract:
A pneumatic slide valve includes a valve housing made of injection-molded plastic material and having a valve bore and a plurality of external ports. The valve housing has an outer housing portion, made of reinforced plastic and determinative for a geometric outer dimension of the valve housing, and an inner housing portion made of non-reinforced plastic and extending continuously in the valve housing. The inner housing portion defines several pressure fluid compartments in fluid communication with the ports and the valve bore at least in a region which is positioned in the area of the pressure fluid compartments, wherein the outer housing portion is molded around the inner housing portion. A slide member is accommodated in the valve bore of the valve housing for displacement in the direction of the axis, for regulating a flow of compressed air between the ports.
Abstract:
A pneumatic gate valve includes a valve housing made of injection-molded plastic material and having a plurality of external ports. Received in the valve housing are a plurality of valve bushings disposed in axial-spaced relationship as to define a valve bore and a plurality of pressure fluid compartments in fluid communication with the ports. A slide member for regulating a flow of compressed air between the ports is accommodated in the valve bore of the valve housing and displaceable in axial direction. The valve bushings are made of plastic material with a same melting temperature as the plastic material of the valve housing so as to realize a material union between the valve bushings and the valve housing, when plastic material is molded around the valve bushings during injection molding of the valve housing.
