Abstract: FIELD: sealing facilities. 
     SUBSTANCE: proposed cover for reservoir contains main housing 31 and gate with hinged part 62 hinge-connected with pressure part 61.  Pressure part is hinge-connected with main housing.  Main housing has cavity 34 with support wall 40 serving as border.  Hinged part is arranged to engage with support wall and turn relative to pressure part in response to pressing downwards onto pressure part.  To control opening of gate in at least two positions, lock mechanism is used.  In first position, lock mechanism provides reliable fixing of pressure part in closed position, and in second position, it provides reliable locking of pressure part in open position.  According to one of design versions, bottom 44 of cavity is made tilted, thanks to which useful volume of reservoir is increased and deflection of pressure part of gate is limited. 
     EFFECT: improved convenience of use of reservoir cover.

Способ отсоединения и удаления первого внутреннего бандажного элемента включает удаление и перемещение по оси сопряженной детали расположенной выше по потоку от первого внутреннего бандажного элемента. Затем осуществляют удаление штифта, препятствующего повороту первого внутреннего бандажного элемента относительно первого наружного бандажного элемента. После чего удаляют штифты из прилегающих по окружности внутренних бандажных элементов и сдвигают их до освобождения матерчатых уплотнений. Затем сдвигают первый внутренний бандажный элемент по направлению оси для отсоединения переднего и заднего краевых крючковидных элементов и перемещают его в радиальном направлении. Изобретения позволяют упростить обслуживание бандажных элементов без повышения сложности их конструктивного выполнения. 3 н. и 6 з.п. ф-лы, 5 ил.

Proposed device is combination of two members: cover plate protecting parts of flanging most liable to chipping and following corrosion - its ribs (inner and outer), and outer plane pointed to mud flow and protecting from stones, water and salt solutions, etc, and sub-fenders which protect inner surfaces of fender and/or body.  According to one design version, said members are installed without relative fastening at which rigid connection of sub-fender with flanging or cover plate is not required and clearance is left between said members over perimeter of flanging which does not affect protecting properties of device.  According to other design version, said members are provided with relative fastening owing to seats made in cover plate and/or sub-fender and/or flanging, and/or by means of third element which is catch.  Invention provides protection against direct action of mud flow, increased service life of metal parts of car body, increased operating properties owing to long-time additional protection of flanging of fender and/or body, practically over entire service life of car, reduced labor input at making and mounting of wheel arch protective members, facilitated process of repair, particularly, replacement of cover plates and restoration of protective coatings.
