摘要:
A liquid hammer prevention device has a casing (K0) led to a fluid channel via passage hole (1), an elastic cushion (50) made of foamed material incorporated in the casing (K0) ; and a diaphragm (F) partitioning the inside of the (K0) into an area led to the fluid channel and another area incorporating the elastic cushion (50). The elastic cushion (50) is "Asker C 30 and 85" according to Japanese Industrial Standard S 6050 measured by the level gauge of a durometer "Asker C," and is 0.30 - 0.70 of apparent specific gravity.

摘要:
The invention relates to a method for producing a membrane reservoir with a metal case. The inventive method comprises the following steps; a) rotating a tubular piece around its longitudinal axis, b) preheating one end of the tubular piece for deformation through heat retraction by strain-hardening, c) strain-hardening the end of the tubular piece by applying at least one pressure tool, selectively heating the target area of said pressure tool to deformation temperature in order to form a floor at the end of the tubular piece with an opening at a collar, said collar being turned outwards, d) forming an inner circular groove in the central area of the tubular piece, e) introducing a membrane system, said membrane system being sustained in the circular groove by a corresponding clamping ring, and f) forming a second floor at the second end of the tubular piece according to steps b) and c).

A surge suppression apparatus (1) comprising a chamber (7) for receiving a liquid subject to pressure variation effects that are to be suppressed and an inlet (9) through which liquid is suppliable to the chamber (7), the arrangement being such that, in use, inlet flow exiting the inlet (9) is directed towards a wall (7c) of the chamber (7) at an oblique angle to that wall.
摘要:
Eine Vorrichtung zum Reduzieren von in einem Hydrauliksystem insbesondere durch eine Pumpe verursachten Druckpulsationen weist ein Ausgleichsvolumen (41) auf mit einer im Volumen angeordneten und das Volumen abschliessenden, verschieblichen Wandung bzw. Membran (39), welche auf einer Seite mit den Pulsationen beaufschlagt ist und an der entgegengesetzten Seite mit einem Gegendruck, welcher wenigstens nahezu dem mittlerem Druck im Hydrauliksystem entspricht. Das an der entgegengesetzten Seite der Wandung bzw. Membran (39) angeordnete Druckausgleichsvolumen (43) ist über eine Ausgleichsleitung (51) mit dem Hydrauliksystem verbunden, wobei die genannte Leitung (51) in Fortpflanzungsrichtung der Pulsationen in bezug auf das Ausgleichsvolumen (41) nachgeschaltet in das Hydrauliksystem mündet.
摘要:
The invention relates to a tubular element (100) which is inserted into a liquid-conducting conduit. Said tubular element (100) comprises an annular chamber (25) internally and radially defined by a tubing section (30) made of a material with an elastically flexible surface. The tubular element (100) acts as a flexible damping conduit section. Alternatively, if the annular chamber (25) is joined to a vacuum chamber via a connector (21), and the tubing section (30) is inflated inside the annular chamber (25), the tubular element (100) serves to temporarily accommodate a quantity of liquid, for example in order to withdraw a dye bath from the outlet channel of an applicator for dying webs of endless fabric.
摘要:
The oscillation damper (10) has as membrane a sleeve-like elastomer molding (17). Contained within a bore (11) of a housing (12) and providing a seal at its open end, the molding (17) surrounds a projection (25) of a support member (23) in the bore (11). In one lateral face (36) of the projection (25) there is a channel (37) communicating with a chamber (39) in the projection. Exposed to brake fluid on its outer surface, the molding (17) with its inside wall (19) delimits a hollow space (45) formed on the projection (25) of the support member (23), having atmospheric pressure. The oscillation damper (10) can be used in hydraulic anti-lock braking systems in motor vehicles.
摘要:
The invention concerns a waterborne-sound absorber for use in pipes, the sound absorber including an insert of flexible material which is embedded in a support ring. The invention calls for the support ring (2) to have three openings (3) in it and for the support ring (2) to have two annular zones (4, 5) which are connected to each other by three link elements (6).
