The invention relates to a cable gland with a grommet comprising a tubular base body made from an elastic material and extending in a direction of a cable gland axis from a first outer end to a second outer end. The tubular base body has at least one flow channel arranged between the first and the second outer end and extending in circumferential direction along an inner surface of the tubular base body. At least one filling hole extends from said flow channel radially outwards through the tubular base body to fill an inner space of the tubular base body with an adhesive. A first circumferential sealing lip arranged in the region of the first outer end and a second circumferential sealing lip arranged in the region of the second outer end to seal an inner space of the tubular base body when mounted on a cable with respect to the cable.

An assembly secures a connector of an external power supply in a rail vehicle. The connector is enclosed by a housing and by a rotatably mounted flap. The flap and the housing each have a slot configured to receive a catch. The flap can have two positions: a first position, in which the flap covers the connector and thus prevents access to the connector, and a second position, in which access to the connector is possible. The flap supports a lock cylinder, which can be switched by a key into two states: in a first state, the key can be pulled out of the lock cylinder, and in a second state, the key is secured in the lock cylinder against removal. A catch is rotated into both slots or out of both slots by the lock cylinder.

A self-cooled reactor apparatus includes: a pair of frames attached to a vehicular mount, a coil disposed between the pair of frames and fixed to the frames, a cover disposed between the pair of frames, and a protective member. The coil is covered by the cover having at least a portion thereof in which through-holes are formed. The protective member, while retaining a flow passage for air from the through-holes to the coil, blocks a space between the through-hole and the coil in a penetration direction of the through-holes.

A rubber composition for a cover layer of a hydraulic hose includes: ethylene vinyl acetate copolymer (EVA); and ethylene-propylene-diene terpolymer (EPDM). In an embodiment, the composition includes ethylene vinyl acetate copolymer (EVA) and ethylene-propylene-diene terpolymer (EPDM) and additives. The additives may include carbon black with a content of around 15 phr, silica with a content of around 20 phr, di-octyl adipate with a content of around 18 phr, aluminium hydroxide with a content of around 124 phr, magnesium hydroxide with a content of around 30 phr, and other chemicals with a content of around 20 phr. The other chemicals may include zinc oxide, peroxide curative, antioxidant, coagents and processing aids.

A system and a method for monitoring pressure inside a railway vehicle comprise a carriage pressure detection device, a control device, and an alarm device. The control device is configured to receive and process a pressure signal collected by the carriage pressure detection device, perform calculation on and analyze the collected data, and transmit an alarm signal to the alarm device as an alarm when a preset alarm condition is met. When a pressure protection device fails, pressure changes inside the vehicle are monitored in real time by the carriage pressure detection device functioning independently of the pressure protection device.

An open part that has an opening surface that is perpendicular to the horizontal direction is formed in a housing of a vehicle control device. An interior of the housing is divided into a first space including the open part and a second space by a partitioning member, a main surface thereof having a hole formed therein and opposing the opening surface. The semiconductor cooling unit is housed in the first space. The semiconductor cooling unit is detachably attached in a direction in which the opening surface and the partitioning member oppose each other. An engaging member arranged on the cover of the semiconductor cooling unit engages a guide arranged on the housing, and the guide supports weight of the semiconductor cooling unit. A heat sink is provided on a base plate and forms a vertically-directed flow passage.
