摘要:
The invention relates to a valve (1), in particular for a heat engine, comprising: a body (2) containing (i) a housing (8) in which at least one bearing is disposed, and (ii) a conduit (3) through which a fluid can flow; a shutter (5) pivotably mounted in the body (2) by means of a shaft (7) received in the bearing with radial clearance; and at least one return member secured to the body (2), said shutter (5) pivoting between an open position, and a closed position in which it is in contact with the body (2) at a first contact zone of the shutter located on a first side of the shaft (7) and at a second contact zone of the shutter located on a second side of the shaft (7) opposite the first side, said bearing being designed to allow the radial movement of the shaft (7) in the bearing as the shutter (5) moves from the open position into the closed position, and said return member being designed to guide the radial movement of the shaft (7) in a pre-determined direction.

Verschlussklappe (1), insbesondere für einen Bypass (2) eines Abgasturboladergehäuses (3), mit einem in dem Abgasturboladergehäuse (3) in einem Lager schwenkbar gelagerten Schwenkarm (4), wobei von dem Abgasturboladergehäuse (3) zu dem Lager ein Widerlager (5) für den Schwenkarm (4) gebildet ist, wobei zwischen dem Schwenkarm (4) und dem Widerlager (5) eine Punkt- oder Linienberührung ausgebildet ist. Durch die erfindungsgemäße Ausgestaltung wird die Reibung zwischen der Verschlussklappe und den Lagern minimiert, bei gleichzeitig optimaler Anpressung der Verschlussklappe auf den Bypass.

Embodiments of an apparatus for sealing a substrate transfer passage in a chamber are provided. In one embodiment, an apparatus for sealing a substrate transfer passage (316) in a chamber includes an elongated door member (402) having a concave sealing face coupled to an actuator by a flexible coupling (419). The flexible coupling (419) configured to allow movement of the door member (402) relative to the lever arm (413) in at least two planes.

An exhaust valve includes a valve body (18) that is fixed for rotation with a shaft (20) supported by at least one bushing (30). A single spring (50) is used to bias the shaft to hold the valve body in a valve closed position, and to exert an axial load on the shaft to seal the shaft against the bushing to prevent exhaust gas leakage.

The invention relates to an arrangement (4) of a flap (5) in a channel (2) of a fresh gas arrangement (1) in order to supply an internal combustion engine, in particular, a motor vehicle, with fresh gas. Said arrangement comprises an actuating device (7) which is used to pivot the flap (5) about a pivotable axis (6). The actuation device (7) comprises an actuator (8) which engages with the flap such that it can be pivoted in a manner which is eccentric in relation to the pivotable axis (6) during the actuation thereof, in order to reduce the load of the actuation device (7).

An engine shutdown valve comprises a housing and a gate movable within a housing between a first position where the air flow through the shutdown valve is substantially unrestricted to a second position where the opening is restricted thereby stopping air flow. The gate is pivotable about an axis. The gate has an extension with a recess which is engageable by a piston movable between a first position where the gate is held in its latched position and a second position out of engagement with the recess so as to allow the gate to move to a position where the air passageway is closed. The gate is movable by a rod attached to the gate lever and which rod is biased by a compression spring mounted within a sleeve. The spring is adjustable to increase or decrease the force on the gate and such adjustment can be accomplished from outside the shutdown without disassembly of the entire valve.
摘要:
Die Erfindung betrifft ein Schnellöffnungsventil, insbesondere für Feuerlöscher, mit einer im Strömungskanal vorgesehenen Dichtmembran, die über einen Membranring eingespannt und von einer Klappe unterstützt ist. Die Klappe wird einerseits mittels eines plastisch verformbaren Scharniers und andererseits mittels eines quer zur Strömungsrichtung verstellbaren Entriegelungskolbens abgestützt.
