    摘要： A rotary displacer mechanism of the rotary-abutment type utilizes improved piston and sealing rotor design to reduce internal leakage and increase volumetric efficiency. A rotary-abutment positive displacement mechanism typically comprises a housing which encloses a rotary piston having a plurality of lobes and a cylindrical sealing rotor having a plurality of cavities for accepting the piston lobes during rotation. The improved piston design consists of a cylindrical stationary block around which only the lobes of the piston are rotatable. This design reduces bearing loads and allows for improved sealing characteristics. In addition, the sealing rotor is constructed with two axial sections of unequal diameter to provide a valving operation on either the intake or the discharge ports of the displacer, as required, and, at the same time, maintain communication between working volumes in the main rotor and sealing rotor bores. The design, by allowing the sealing rotor to perform the valving function, minimizes dead volume in the mechanism thereby increasing volumetric efficiency.

    摘要： A device for pumping fluid or for converting the power in a flow of water into constant rotary motion. A Roots-type pump or motor utilizing two centrally-mounted oval rotors is coupled to a transmission designed to convert the non-constant speed characteristic of the Roots-type device into constant rotary motion. The rotors are synchronized through the transmission, thus eliminating the need for gear teeth on the rotors and allowing leakproof seals of a resilient material to be used to surface the rotors. Two embodiments of the transmission are disclosed, one involving angled Hooke joints and the other utilizing a gear train including focus-mounted elliptical gears.

    摘要： A housing (2) of a Roots pump (1) supports a drive shaft (3) and a driven shaft (4) with radial bearings (32, 33) so as to be rotatable. The housing (2) is formed by joining an upper housing member (20) to a lower housing member (10). The lower housing member (10) has lower bearing support portions (13), and the upper housing member (20) has upper bearing support portions (23). Opening edges (13a) of each lower bearing support portion (13) are positioned above the centers (P1) of the bearings (32, 33). An opening width (T1) of each lower bearing support portion (13) is smaller than the diameter (D1) of the bearings (32, 33). This structure suppresses the bearings (32, 33) from being separated from the lower housing member (10) during an assembling operation of the fluid machine.

    摘要： The rotary piston machine has a bypass channel, which is formed through two openings (15, 16) provided in a sidewall (6) of its delivery housing (4) and a channel (17) extending into this sidewall (6) in such a way that the bypass channel (17) is restricted on one side by a wall area of the sidewall (6) and on the opposite side by a channel cover (19) embedded in this sidewall (6). The housing (25) of a pressure relief valve (14) is formed cup-shaped in the channel cover (19) in whose cylindrical inner surface (27) a closing member (2) is operated piston-like. The machine which is designed from few individual parts is suitable especially for the space-saving and direct coupling in the engine space of a motor vehicle, in which its pressure relief valve (14) provided in the bypass channel overcomes the disadvantages of the rotational speed-dependent pressure difference between suction and pressure sides.

    摘要： A rotary device (11) has a first rotor (12) rotatable about a first axis and having at its periphery a recess (14). A second rotor (13) is counter-rotatable to said first rotor (12) about a second axis, parallel to said first axis, and has a radial lobe (15). The first and second rotors (12,13) are coupled for rotation and are intermeshed such that, for a portion of the rotation of the rotors (12,13), there is defined between the first and second rotors (12,13) a transient chamber of volume which progressively decreases on rotation of the rotors (12,13). Means (27,28) are provided for monitoring the clearance between the rotors (12,13). Means for adjusting the clearance between the rotors (12,13) are provided.
