Description

The invention relates to mechanical engineering, in particular, to devices for discharging (draining) fluid from the crankcase of vehicles and can be used to drain oil from the crankcase of engines.

A device for draining the fluid from the crankcase of the vehicle, installed in the housing of the crankcase and made in the form of a bolt, blocking the drain hole when installing instead of the stopper receiving fitting and opening the specified hole when draining the liquid from the crankcase, as well as filling it (patent RU 2157456 C2, published 10.10.2000.).

The drain plug of the oil casing of the internal combustion engine is also known. It contains two parts installed one on the other in the thread, the outer part of which is designed as a cap with one overflow hole to communicate the cavity of the tank with the drain hose and is equipped with a nut flange and an external thread to be installed in a drain hole of the crankcase, with a sealing gasket placed between the flange and the crankcase, and the internal one is designed as a sleeve with a flange and is provided with a threaded section for connection with a plug or slit willow hose. The stopper is also provided with a clamp of the extreme positions of the sleeve located in the cap flange, the bypass holes are made in a staggered manner on the cylindrical surface of the cap and the latter on its inner surface below the bypass holes is provided with an annular groove to accommodate the sealing element between the mating surfaces of the cap and the sleeve (RU Patent 2027868 C1 , published 01/27/1995.).

A common drawback of the known drain devices is the unsatisfactory performance characteristics and high labor intensity of lubricating and filling operations, since to drain the oil from the engine crankcase it is necessary to unscrew the drain devices by directly rotating them while being under the crankcase. When turning away at the time of their separation from the body, there is a chaotic outflow of fluid, the jet of which falls on the hands of the operator and the tool.

As the closest technical solution to the claimed utility model, a drain device is selected, comprising a housing with a liquid, a sleeve attached to the housing, and a stopper. The sleeve is made in the form of a cylindrical glass with a thread and a thrust collar with edges under the wrench in its upper open part, by means of which the glass is tightly connected to the bottom or bottom side part of the body. The cavity of the glass communicates with the housing with a liquid. The cork is made in the form of a bolt with a turnkey head and is installed with a free end in a glass on a thread perpendicular to its axis with the possibility of alternately blocking the cavity of the glass and passing the liquid from its cavity through the hole under the cork in the wall of the glass (RU 2772883 C2 published 27.08.2001g ).

The disadvantage of the closest analogue, as well as the well-known drainage devices, is unsatisfactory performance, in particular, the large amount of time it takes to maintain the engine and the inconvenience of maintaining the crankcase when draining or replacing fluid.

A technical problem, the solution of which is provided by the claimed utility model, is the creation of a drain device, which is free from the drawbacks of the known analogues and allows to increase the convenience of lubricating and filling operations.

The technical result obtained when using the claimed utility model is to reduce the time for servicing the engine.

The technical result is achieved by the fact that a drain device containing a threaded plug adapted to be placed in the pan of the crankcase of the engine in the drain hole, according to the utility model, contains a rod mounted in the engine block and connected to the stopper at one end. end in the crankcase.

In this case, according to the utility model, the plug can be fixed rigidly at the end of the rod.

In this case, according to the utility model, the second end of the rod may extend into the hole located at the top of the engine.

In this case, according to the utility model, the second end of the rod may extend into the filler neck of the engine.

This utility model is illustrated by drawings (Fig. 1-6), examples of the discharge device on which, however, are not the only possible, but clearly demonstrate the possibility of achieving the stated technical result.

The figure 1 shows a general view of an internal combustion engine with a drain device in one of the embodiments; figure 2 shows a variant of the location of the plug in FIG. 1, in FIG. 3 shows the position of a plug with a rod in the first embodiment when draining a liquid (for example, oil) from the crankcase of the engine; FIG. 4 is a general view of an internal combustion engine with a drain device in another embodiment; FIG. 5 is a variant of the location of the plug in FIG. 4, in FIG. 6 shows the position of the plug with the rod in the second embodiment when the oil is drained from the crankcase of the engine.

According to the utility model, the drain device comprises a threaded plug 1 located in the pan 2 of the crankcase of the engine 3 (FIGS. 1, 4). If necessary, a sealing gasket (not shown) can be installed between the stopper 1 and the body of the pallet 2. The stopper 1 is placed in the hole 4 to drain the oil. The drain device contains a rod 5 mounted in the motor housing 3, with one end 6 of the rod 5 extending into the crankcase 7. The same end 6 of the rod 5 is connected to the stopper 1 (the stopper 1 is located on the rod 5) (Fig. 1-6).

In one of the embodiments of the tube 1 is installed on the end 6 of the rod 5 with the possibility of removal. The stopper 1 can also be fixed rigidly at the end 6 of the rod 5 (Fig. 1-6). The second end 8 of the rod 5 in one of the embodiments of the drain device may extend into a hole specially made for it, located in the upper part of the engine. The second end 8 of the rod 5 in another embodiment of the drain device may also extend into the filler neck 9 of the engine 3, which can be closed, for example, with a plug (lid) 10 (Fig. 1, 4). The rod 5 may pass through a special channel 11, provided for by the design of the internal combustion engine. Access to the rod 5 is provided through the filler neck 9 of the engine or a special technological hole.

Thus, opening the plug 10 and rotating the rod 5, remotely unscrew the drain plug 1. The plug 1 itself can be turned inside out (Fig. 6), under the crankcase cavity 7, and inwards (Fig. 3) of the crankcase cavity 7 depending on the design drain device.

The inventive drain device works as follows.

Remove the plug 10 (Fig. 1, 4), rotate the rod 5 with a universal key or other tool, which, in turn, unscrews the plug 1. After unscrewing the plug 1, it is pushed down by the rod 5, out of the crankcase 7 (Fig. 6) or lift upward, inside the crankcase cavity 7 (Fig. 3). Fluid leakage occurs. After draining the fluid, the plug 1 is wrapped back. The filling of the liquid occurs through the filler neck 9, after which the plug 10 is installed in place.

When loosening the drain plug 1, there is no need for direct access to it. The cork 1 is turned away remotely, as it is structurally connected with the rod 5 (rigidly or with the possibility of removal). As a result of using the claimed utility model, the operational characteristics of the discharge device are improved, i.e. adaptation of the crankcase of the engine for maintenance, as well as improved working conditions, which reduces the complexity of lubrication and filling operations.
