摘要： A pneumatic rotary coupling (25) for an air pressure installation for one or more wheels of a vehicle, in which the wheel's axle (11) is used as the section of the pipe of the static installation, in accordance to the system of the coupling used. The coupling's stem (49) has one end formed in the shape of a nozzle which extends in the plane of the wheel, disposed as an axial extension of the wheel's axle end. The stem is located rotatable and slidable inside block (35) which is fixed to the wheel's hub cover. A cover (37) fixed to the block presents a cavity (45) with an edge that defines a seat for a plastic bushing (47) that supports the coupling's stem. The external surface of this bushing is conformed by grooves (53) that communicate the cavity towards the orifices linking with the tires. One method allows for the detection of bearing faults using the same coupling when the axial sliding of the stem is sufficient to vent the pressurized air.

摘要： A cooling unit includes a housing (1) with an evaporating unit (7) installed on the inclined roof of a cabin and an external water reservoir (29) with a rising pump (31) installed lower down, between the cabin and the rear part of a truck. The return hose (15′) of the excess water gutter (45) coming from the evaporator has an upper end (14) connected to the front part of the gutter and then it crosses a rising stretch to leave by the rear part of the housing and descending down to its lower end which is connected at the outlet of the pump, together with the feed hose (6) of the evaporator by means of a coupling (47).

摘要： A remote pressure-controlled three-way valve device has a plunger axially traversed by an inlet passage normally closed by a spring-urged inlet valve. The plunger's outer sidewall has a recess in which an O-ring extends to abut against the steps of the recess to limit the plunger stroke and keep an outlet passage closed to a venting port formed in the sidewall of the body of the device. O-ring prevents short-circuits between the inlet passage and the vent port and a spring for counteracting friction between the O-ring and the device inner wall. Filters arranged in respective ports connectable to the input air-pressure supply and the tire inner tube provide fixed seats for the springs to bear on. The plunger may dwell in a stable intermediate position that opens the outlet or deflation passage is controlled by sending an air pressure through the inlet port at 50% of the normal pressure.

摘要： An oil-gauge for the axle-end of a vehicle includes a transparent or translucid lid (15) for inspecting the level of oil in a chamber (13) housing the wheel-mounting bearings. A disk partition (23) is bolted to the inside of the lid to form a shallow subchamber (25). The disk is provided with orifices for oil level in the subchamber to follow the oil level in the main chamber. The visible surface (29) of the disk is painted white and the subchamber houses one or more loose elements (31) to wipe the inside of the lid clean.

摘要： A pressure sensor for an apparatus for controlling and maintaining air pressure in vehicle tires. The vehicle compressor outlet is connected through individual pneumatic tire circuits to each vehicle tire, via rotary couplings in the associated axles. Each tire circuit includes tubing for carrying air and monitoring tire pressure, the circuits supporting pressure sensors and electrovalves housed in a control unit in the dashboard of the vehicle. The sensor includes a piston which causes a shutter to move in and out of the light path of a LED/phototransistor device. When the sensor signals low tire pressure via a an electronic circuit, the corresponding electrovalve is energized for the compressor to pump the tire up back to its set pressure. The sensor further includes means for varying the set point.
