Embodiment Construction

[0028] The exhaust valve 5 has a valve disk 6 that works together with the valve seat set in the 4 area of the exhaust port. It is installed on the lower end of a main shaft valve lever 7.Connecting the exhaust channel 8 with the exhaust port, the exhaust channel is open to the combustion room 3 when the seat is provided from the seat with the exhaust valve.Configure a set of exhaust valve shell 9 installed on the cylinder head 2 for the exhaust valve 5. The exhaust valve shell includes the exhaust channel 8.Install a circular circle 9A that is embedded in the cylinder head 2, including a valve seat with a limited exhaust port 4.In addition, the valve cover 9 also includes a guide cover 10 of the rod 7 of the exhaust valve 5.The guide cover and exhaust port 4 are set up and extended from the wall area of the upper part of the exhaust channel 8 from the upper wall of the valve case to the upper area of the valve case.Guide sleeve 10 pass through the wall area of the exhaust channel...

Abstract

In a two-stroke reciprocating piston engine having at least one cylinder (1) whose combustion chamber (3) has an outlet opening (4), which can be controlled by an outlet valve (5) which can be actuated by means of an actuating device which comprises a feed device and a return device, and on whose cylinder head (2) is placed a valve housing (9) which comprises an outlet duct (8), which adjoins theoutlet opening (4) of the combustion chamber (3), and a guide sleeve (10), which engages through the upper wall of said valve housing (9), for a shank (7), which extends through the outlet duct (8), of the outlet valve (5), wherein the return device has a piston (15), which is attached to the valve shank (7), and a working space (17) which is delimited by said piston (15), is acted on with compressed air and is sealed off from an annular gap (11),; which is present between the mutually facing guide faces of the guide sleeve (10) and valve shank (7), communicates with the outlet duct (8) and can be supplied with oil, by a sealing device which is arranged in the region of the upper, outlet-duct-remote end of the annular gap (11) and has at least one sealing ring (22), according to the invention, it is possible to provide a simple design and a service-free mode of operation in that, above the sealing ring (22), which faces towards the outlet duct (8), of the sealing device, an oil reservoir (24 and 31 and 36) is provided which can be filled with oil and is filled with oil at the upper side, which faces away from the outlet duct (8), of said sealing ring (22).

Description

Technical field [0001] The invention involves a large two -stroke large diesel engine. Background technique [0002] One such settings are known by DE 101 61 438 A1.For the cyclical gaps between the guidance surface and the valve rod, the fuel is available to achieve reliably preventing the burning residues from the exhaust channel from entering the cycle gap. In the pastThe destruction of the sealing ring.On the device known from the above DE 101 61 438 A1, the ring clearance is provided with the diverted oil from the hydraulic operation device equipped with the exhaust valve.The ingredient device set on the known device causes high manufacturing costs and expensive structural methods of maintenance costs. Invention content [0003] Therefore, based on this as the starting point, the purpose of the present invention is to improve the above -mentioned types of device with the help of simple and low -cost measures, so that the ingredients device that can be lacked so far, but i...
