Abstract: A splash lubrication system is provided for motor vehicle transmissions and comprises an oil sump (42) in the bottom portion of a case (30). The case (30) accommodates a transmission shaft (31) provided with gears (34 to 37) which are immersed in the oil at least partly when the said oil sump (42) is filled completely. In order to prevent the synchronizing mechanism from being blocked by cold and, consequently, very viscous oil in the presence of extremely low operating conditions--a condition which could lead to unsynchronized faulty gear shifting operations and, thus, damage to the transmission, the oil sump (42) is connected with a cavity (33) into which oil is drawn from the oil sump (42) under low operating temperature conditions of the transmission. To this end, preferably, an expansion body (38) is arranged in a cavity (33) in a transmission shaft (31) which contracts under cold conditions, and the cavity (33) is connected with the oil sump (42).

Abstract: A seal for the drive shaft of a gear pump for polymeric materials dissolved in a fluid solvent is disclosed, and which is adapted to prevent the polymeric material from leaking and hardening on the drive shaft. The seal includes a pair of axially spaced apart annular packing seals surrounding the drive shaft so as to define an annular chamber, and means for supplying a pressurized shielding inert gas, such as nitrogen, into the annular chamber. An outlet line is connected to the lowest portion of the annular space and leads to an air tight container which also contains a shielding inert atmosphere, and such that any polymeric material which leaks along the drive shaft and enters the annular chamber remains in solution, and is withdrawn into the air tight container. A valve is also provided on the container for periodically draining the withdrawn polymeric material therefrom.

Abstract: A fuel injection pump includes a reciprocating plunger and a control sleeve slidably fitted over the plunger, the prestroke of which is varied by vertical movement of the control sleeve. The control sleeve is provided at its upper end with a fuel discharge groove, through which the fuel contained in a fuel-pressurizing chamber is discharged after the end of injection. The control sleeve also has to pressure escape passage. A variation in the effective stroke allows the pressure of fuel contained in the fuel-pressurizing chamber to be selectively regulated by the pressure escape passage, thereby controlling the pressure of fuel to be injected.

Abstract: A lubricator so constructed that a cover provided with a substantially horizontal air conduit including an orifice extending therethrough and formed in its upper side with a supply hole extending therethrough to the orifice is received on the oil cup, a transparent oil drop cylinder including a drop hole extending through its upper side is connected to the supply hole, an adjusting cap integrally provided with a needle valve downwardly projecting from the center of its upper side in alignment with the drop hole and serving to control an aperture of the drop hole is fitted around the oil drop cylinder through thread engagement with the cover or the drop cylinder, an oil reservoir within the oil cup is communicated with the drop hole, and a quantity of oil supplied to the drop hole and dropped through the drop hole into the oil drop cylinder under a suction effect of a pressure differential produced between a pressure acting on the oil surface within the oil cup and a pressure within the orifice is controlled b

Abstract: A splash lubricating device for a horizontal or inclined engine comprises an oil-spoon which is fixed to the connecting-rod of an engine having a cylinder installed on a crank case thereof horizontally or obliquely protrusively therefrom and which is provided with an oil-splash portion formed by bending laterally the lower end portion of the oil-spoon. And the oil-splash portion is turned forward by the connecting-rod along an elliptical orbit inclined forward and downward. The posture of the oil-splash portion is settled nearly parallel with an inrush angle thereof relative to the oil near an oil upper limit level in an oil pan in order to lessen the resistance put thereupon and also inclined forward and downward at a smaller angle than an outrush angle thereof relative to the oil near an oil lower limit level in order to attain good lubricating performance as well as lessen the resistance put thereupon.

Abstract: A first shim mounted on the shaft extending from the high pressure end face of a screw rotor in a screw compressor establishes the operating clearance between the high pressure end face of the rotor and the high pressure end wall of the compressor's working chamber by fixing the axial position of a bearing group which is likewise mounted on the rotor shaft. A second shim, disposed between the bearing group and a spring biased spacer element, is determinative of the distance the spacer element, and therefore the rotor, can travel in a direction toward the high pressure end of the compressor under the impetus of reverse axial thrust. Contact of the rotor with the high pressure end wall of the working chamber is positively precluded because movement of the spacer element, under the influence of rotor movement toward the high pressure end of the compressor, collapses the biasing spring which causes the spacer element to contact a fixed surface of the compressor.

Abstract: A lubricating oil supply system has a pump for automatically supplying lubricating oil from an oil tank to a crankcase of an engine through a passage. A bimetallic strip is cantilevered on a wall of the passage. The bimetallic strip is provided so as to reduce the cross-sectional area of the passage at the bimetallic strip when the temperature of the strip rises and to increase the cross-sectional area when the temperature lowers.

Abstract: A gear pump which includes a pair of intermeshing gears. A housing defines a pumping chamber having peripheral walls surrounding and in sealing contact with the circumference of the gears between an inlet port and a discharge port. Bearing walls are adapted to engage adjacent side faces of the gears in substantially sealing relation. Grooves are provided in the bearing walls for progressively admitting pressure to the gear teeth as the gear teeth move toward the discharge port. The grooves are acruately shaped and diverge toward the discharge port from a point intermediate the inlet and discharge ports and allow compressed air in the liquid to be gradually displaced by liquid under pressure from the pump discharge.

Abstract: A fuel injection pump for internal combustion engines has a pump piston which via a pressure plate rests with a piston bottom on an axially driven tappet with slight play. This contact is brought about by a pressure spring, which is supported on a spring plate so as to grip the piston bottom from behind. To prevent the pressure plate from falling out if the pump piston should become stuck, the spring plate is cup-shaped and includes a cylindrical cup portion having two projecting protrusions. The pressure plate has a radial flange adapted to rest on the projecting protrusions. Those protrusions and the radial flange are adapted to one another such that the pressure plate can be introduced in a predetermined position through the protrusions. The piston bottom located between the pressure plate and the plate bottom of the spring plate prevents the pressure plate from being able to assume a position, after assembly, in which it could slip and escape back outwardly through those protrusions.

Abstract: A two-stage gear pump with two gear sets each having a pinion telescoped onto a slotted drive shaft with a press fit and also positively keyed to the shaft. One key in the slot of the shaft includes radial ears establishing a positive coupling between the shaft and one of the pinions and also includes cantilevered spring fingers which enhance the press fit between the shaft and the other pinion.

Abstract: A rotary piston compressor, particularly Root's type compressor, includes a housing which is made of only two portions, one of which is cut-shaped and accommodates pistons rotating in opposite directions, and the other of which is formed as a cover closing the end face of the first portion. The two portions are connected to each other and positioned relative to each so that they abut each other along a separation plane which extends centrally of a suction connection and a pressure connection formed on the housing diametrically opposed relative to each other.

Abstract: A device for controlling the application of lubricant to parts of a locomotive or a vehicle is taught. Briefly stated, the distance traveled by the locomotive or the like is computed, with lubrication to a component then being provided. The distance between lubrication application may be adjusted, as well as the amount of lubrication being applied. Further, this rate and amount of lubrication, as well as the use of lubrication at all, can be manually or automatically adjusted according to various sensors such as braking, sanding, reversing curves or the like.

Abstract: An oil dispenser for internal combustion engines having a crankcase includes an oil-containing, airtight reservoir disposed at a vertical location above the crankcase. A conduit connects the reservoir and the crankcase in order to establish fluid communication between the reservoir and the crankcase. The conduit has a lower end disposed in the crankcase at a level at which oil is desired to be maintained in the crankcase. A solenoid-activated valve is disposed at the lower end of the conduit to selectively permit or prevent the flow of oil through the conduit. The solenoid-activated valve includes a cup-like member which surrounds and is fitted against the lower end of the conduit upon valve closure. A control means is connected to the solenoid-activated valve for opening the solenoid-activated valve only after the engine has ceased operation and after a predetermined period of time has elapsed.

Abstract: Oil normally having refrigerant gas entrained therein is drawn from a sump. A portion of the oil is returned to the sump to agitate the oil in the sump to enhance gas separation therefrom. The remainder of the oil is subjected to centrifugal separation to remove the entrained refrigerant. The separated refrigerant is vented while the separated oil is fed to the lubrication system where contaminant removal takes place.

Abstract: This invention relates to a suction housing of a lubricating-oil pump inserted in a lubricating-oil storage tank of an aggregate of vehicles having a distributing regulator with a mass that is guided in the direction of the accelerating forces affecting the vehicle for the regulating of valve openings. In order to obtain a suction housing with a low overall height and a simple arrangement of valves, the distributing regulator is developed to be plate-shaped in which case the valves are movably suspended at the sides of the distributing regulator.
