Abstract: A pressure vessel includes a pot-like receptacle and a lid for placing thereon, the two being detachably locked together and including a circumferential sealing ring made of elastically yielding material which is located in the region of a circular edge of the lid and a circular edge of the pot for the purpose of sealing the interior against a drop in pressure. Sealing lips of the sealing ring come into close contact with the edge of the lid and the edge of the receptacle, in which case, for producing an automatic pressure-control mechanism, the sealing ring is formed over at least one portion of its circumference in such a way that it is deformed, under a pressure inside the vessel which exceeds a given value (response pressure), so as to form a venting gap between the receptacle and the lid.

Abstract: The invention relates to a steam pressure vessel consisting of a receptacle and a lid, said receptacle and lid each having a long handle and being designed to be tightly joined together by way of overlapping peripheral segments along the lines of a bayonet catch, with the interposition of a sealing ring between the edge of the pot and the edge of the lid, characterized by the combination of at least two closing and opening safety devices, in which case a first safety device comprises a safety valve, the body of which is held in the open position by a spring-biased slide (10) until receptacle and lid are brought into the locked position by turning the two handles (1, 11) so that they lie one on top of the other with the coordinating peripheral segments completely overlapping, and a second safety device raises the sealing ring from the edge of the lid by means of a safety element (safety cam 7) spring-biased in the open position until receptacle and lid are brought into the locked position.

Abstract: The invention relates to a valve unit for a pressure vessel, the latter consisting of a receptacle and a lid which can be placed on said receptacle in such a way as to make it pressure-tight and said valve unit including: a safety function, pressure-relief function and pressure indicator function; adjustable indicator levels and pressure levels; an indicator pin (4) or indicator piston (10) which is supported against an indicator spring (7), can move in axial direction and bears on its portion becoming visible upon pressurization, due to its emergence from a valve housing (12), indicator rings, for example, for indicating the pressure inside the vessel; and comprising a valve body (5) which is movable in axial direction against the action of an exhaust steam spring (6) and, in the closed position, rests against a seal seat (19), lifting off from this, when a given pressure inside the vessel is exceeded, to uncover a pressure-relief aperture (20), in which case both the indicator spring (7) and the exhaust ste

Abstract: A pressure vessel including a container and a lid for placing thereon. By twisting the lid and container relative to each another, the container and lid can be detachably locked together by a peripheral locking segments configured along the lines of a bayonet fastening. A circumferential sealing ring is in the region of the lid edge and the container edge for sealing the interior of the container against a drop in pressure when said container and lid are in the locked position. The pressure vessel including an auxiliary device or aid for correct positioning of the lid on the container. The positioning aid comprising a downward-projecting positioning element in the region of the lid edge which, when the lid is correctly positioned on top of the container, can be inserted into a recess which is open towards the top and in the region of the container edge.

Abstract: A cooking vessel has a container having an encircling container margin bent outwardly and with a cover having an encircling cover margin bent outwardly. The container can be closed airtight by the cover with the aid of a closing mechanism acting on the container margin and cover margin. The closing mechanism comprises a closure ring extending over the container circumference with a C-profile cross section open radially inwardly, which, with the aid of an actuating mechanism, can be moved from an open position with greater diameter, in which the cover can be lifted from the container, into a closed position with lesser diameter, in which the container margin and the cover margin are clamped together by interspacing a sealing ring between a lower flank and an upper flank of the closure ring.

Abstract: The invention relates to a pressure cooker with a container that can be airtightly closed with the aid of a cover, which can be placed upon a container edge and locked with it. A closing mechanism is provided on the cover. The closing mechanism includes a total of four arcuate closure members, acting distributively over the periphery of the cover and pivoted on the periphery of the cover. The closing mechanism can be moved by an actuating device from an open position, in which the cover can be removed from the container, into a locked position to extend underneath the container edge. In the locked position, the cover is pressed at its periphery against the container edge by interspacing an encircling ring. The total (for example four) closure members are combined into (for example two) groups of two closure members each of which are connected with hinges.

Abstract: A pressure cooker includes a container intended to hold cooking produce and which can be closed pressure tight with a cover that can be set on a rim of the container and locked thereto. The cover includes closing members movable between radially inward open positions, whereat the cover can be removed from the container, and radially outward locking positions, whereat the circumference of the cover is pressed against a region of the container rim with a circumferential sealing ring therebetween. The inside of the wall of the container in the region of the container rim includes a locking shoulder directed, for example, toward the container bottom, and a sealing shoulder directed, for example, toward the container opening. In the radially outward locking positions, the closing members are braced against the locking shoulder, thus pressing the sealing ring against the sealing shoulder.

Abstract: A cooking vessel includes a vessel body having a spill rim extending outwardly and bent around the vessel body. A vessel handle is attached to a wall of the vessel body. A cover than can be set closingly on the spill rim has at least one cover handle. The vessel body and the cover form a spill and ventilation appliance. To guarantee a defined venting and a simple, more reliable, and also defined pouring with more reliable handling, the wall of the vessel body in at least one peripheral region of its upper rim has a larger slope than in remaining peripheral region of the rim due to shortening the spill rim. A rim of the cover in at least one peripheral segment has at least one arch projecting in a radial direction slope when correspondingly positioning the cover through rotation. The remaining peripheral region of the vessel wall without the larger slope has a circumferential length that is at least as large as the peripheral segment of the cover having the at least one arch.
