A rotary piston pump assembly includes a rotary piston pump having a pump housing. First and second outlets lead fluid out of the pump housing. The fluid is returned into the pump housing through the first outlets and the first outlets are closed during a portion of the rotation of the pump.

Valve control of internal combustion engines by means of a cam-driven

A rotary piston pump assembly includes a rotary piston pump having first, second and third sectors. Pistons successively pass through the first, the second and the third sectors during one rotation. The pump has a pump output equal to zero during passage of the pistons through the first sector.

Valve control of internal combustion engines by means of a rotary piston

A valve drive assembly for an internal combustion engine includes a given number of pistons, the given number of inlet or outlet valves each being connected to a piston and independently movable by hydraulic fluid acting upon the pistons, at least one rotatable link disposed in a housing for aiding in shutting off and releasing a supply of hydraulic fluid to the pistons at regular intervals, and an auxiliary shaft supported in the rotatable link and driven by a crankshaft. First and second supply lines for hydraulic fluid lead from a hydraulic pump to first and second annular grooves formed in the housing. The rotatable link has the given number of radial third and fourth conduits formed therein communicating with the first and second annular grooves. The auxiliary shaft has fifth and sixth annular grooves formed therein communicating with the third and fourth conduits. Fifth and sixth conduits communicate with the fifth and sixth annular grooves. Seventh and eighth conduits communicate with the fifth and sixth conduits. Third and fourth annular grooves lead from the seventh and eighth conduits to first and second conduits which lead to the pistons. Ribs divide the fifth and sixth annular grooves into the given number of sectors.

Valve drive with a hydraulic transmission and a characteristic variable

Valve drive for a combustion engine with an hydraulic transmission system between a control member and a valve includes a device for stepping up the hydraulic transmission.

Hydraulic valve drive for internal combustion engines

A gas-static bearing including a bearing shell formed of porous material compacted at bearing surfaces thereof for supporting a shaft, the bearing surfaces being distributed over a first group of surfaces consisting of at least two cylindrical jacket surfaces disposed concentrically to one another and about a longitudinal axis of the bearing shells and a second group of surfaces consisting of a plurality of circular surfaces disposed in succession along the axis.

Gas-static bearing with subdivided bearing surfaces

Static pressure-type gas bearing for a high-speed rotary shaft, comprising a porous bearing bushing formed of a pair of hollow cone frustums connected to one another at respective narrow ends thereof.
