Abstract

The invention provides a turnover-prevention wet type oil sump of a piston type engine. The turnover-prevention wet type oil sump comprises a wet type oil sump body, a foam elimination plate, an oil baffle, an oil suction pipe and a gravity valve. The oil baffle is arranged on the upper portion of an inner cavity of the wet type oil sump body. A downwards-protruding oil outlet is formed in the middle portion of the oil baffle. The foam elimination plate is arranged at the position of the oil outlet. The upper end of the oil suction pipe penetrates a through hole in the middle portion of the foam elimination plate. The lower end of the oil suction pipe communicates with the gravity valve. The oil baffle is arranged in an oil pool of the wet type oil sump body, a certain amount of engine oil can be stored in the oil sump body through the oil baffle when the engine is overturned, a traditional oil suction plate is designed into a one-side oil suction valve body with a gravity valve element, the opening position of the valve body can be automatically regulated through the gravity valve element according to whether the engine is horizontal or overturned, and the effect that the engine oil can be sucked at any time is achieved.

Description

technical field [0001] The invention belongs to the technical field of engine lubrication, and in particular relates to an anti-turnover dry oil sump of a piston engine. Background technique [0002] In the process of researching the piston engine used in aircraft, because the aircraft will turn over a lot in the air, the oil pump will not be able to normally suck the oil at the bottom of the oil pan when turning over, causing the oil circuit to not work normally, and even causing the engine to fail due to lack of oil lubrication. Damage occurs, so it is necessary to consider the engine overturning situation when designing the engine. Contents of the invention [0003] In view of this, the present invention aims to propose an anti-turnover dry oil sump for a piston engine to solve the problem that the oil pump cannot normally suck the oil at the bottom of the oil pan when it is turned over, causing the oil circuit to fail to work normally. [0004] In order to achieve the...
