Abstract: Milking is carried out using milking cups each having a teat rubber liner in which the teat is received. Pressure is periodically applied to the outside of the liner to massage the teat and suction is applied to the milk discharge duct so that the milk is discharged therefrom. A valve in the milk discharge duct in the form of a section of rubber hose has a relatively more elastic zone on its surface and sits in a housing to which pressure is periodically applied during the massage pulse so that the elastic zone is indented to close at least the milk free cross section of the hose. The teats are thus periodically isolated from vacuum which is kinder to the teats and prevents reverse washing effects during the massage phase. In modifications the valve is placed at the end of the teat rubber and a series of massage cushions are used to sequentially massage the teat.

Abstract: A method for preventing undesirable heat losses in a cooling system for liquid-cooled vehicular internal-combustion engines by affecting the flow at the connections of the lines to and from the header tank of the cooling system by measures commonly practiced in flow engineering such that the pressure will be the same at the inlet and the outlet of the header tank, so that with the thermostat closed no coolant is allowed to flow through the header tank and on through the radiator. With a cooling system having an engine vent line which connects to the header tank this method produces, by affecting the flow in the engine vent area and with the engine running and the thermostat closed, a pressure at the connecting point of the vent line for engine venting which is equal to that prevailing at the entry of the vent line to the header tank.

Abstract: The usual relatively long induction passage connecting the compressor of a supercharger between the carburetor and the intake manifold of an internal combustion engine is bypassed during idling condition by a relatively small idle mixture transfer passage which directs the idling fuel/air mixture directly against a heated section of the intake manifold, thereby preventing precipitation of the fuel during idling. An opening between a part of the induction passage upstream from the compressor and a portion thereof downstream from the compressor limits the boost pressure developed by the compressor to a predetermined upper limit.

Abstract: A fuel injection system for an internal combustion engine has an air sensor for metering the intake air flow into the engine and a fuel metering and distributing device hydraulically coupled together. The device includes a plunger rotated by the engine to distribute fuel to respective fuel injectors and axially moved in response to variation in the intake air flow rate to meter the fuel. The axial displacement of the plunger is determined by two opposing hydraulic pressures acting on the opposite ends of the plunger, one of which is varied in accordance with the engine intake air flow rate as detected by the air sensor while the other hydraulic pressure is changed in accordance with the axial displacement of the plunger. Since no mechanical linkage is required between the air sensor and the fuel metering and distributing device, the system can easily be installed in a limited space and, in addition, assure an improvement in the accuracy of the fuel control.
