摘要： The machine has an operating chamber (5) provided between rotary pistons (3), where the chamber changes its volume and/or its length during rotation of the rotary pistons. The chamber is fillable with a compressible operating fluid over an inlet (18). Each rotary piston has an outer contour twisted along their axis of rotation in a screw-like manner. The pistons are twisted such that the chamber is closed by contraction of a piston intermediate area.

摘要： PROBLEM TO BE SOLVED: To provide a quantified rotor type pump that gets rid of any weighty pulsation of discharge, and besides, there is not variation even if it is rotated by each optional angle. SOLUTION: A weighty pulsation of discharge comes forward when to three- lobe type rotors 1 and 2 are rotated at constant velocity. Accordingly, a pair of noncircular gears 7 and 8 are built in a driving part, and in time of a state that a fluid substance is discharged in bulk, each rotational speed rotors is made so as to be at a low speed, but in time of a state that it is discharged in a small quantity, a tooth profile form is determined so as to make it become at a high speed, thereby getting rid of any pulsation.

摘要： PURPOSE:To prevent a rotor from receiving a heat collected to one position rotor by successively transferring the outer circumferential surface of each rotor forming a space part to suck and discharge a fluid. CONSTITUTION:A displacement type pump is a one in which four rotors 2..., for example, are combined together, and each rotor 2 is formed from a disc body formed into the same elliptical form. Between the four rotors 2, a space 3 the volume of which is changed decreasingly or increasingly during the time when each rotor is rotated in contact to each other. An inlet port 5 and a discharge port 6 are formed on an cap in such a manner as to be opposite to the center part at the time of maximum volume of the space part 3. Each rotor 2 is formed by an envelope drawn by both identical large circular arches 10 having symmetrical points on a virtual circle 7 having an optional radius as centers and a radius larger than its radius, and both small circular arches 11 having centers on the virtual circle 7 and mutually connecting both the large circular arches.

摘要： The invention relates to a rotary piston engine (2) which operates as a pump, condenser or motor for a liquid or gaseous medium. The rotary piston engine (2) has a first gear (4) having a first central axis (I), a second gear (6) arranged opposite the first gear (4) and having a second central axis (II), and a drive shaft (8) having a third central axis (III) and a sliding plane (10, 12) fixedly connected to the drive shaft (8). The first central axis (I) and the second central axis (II) enclose an angle (α3) which is not equal to 180°. The third central axis (III) and at least one central axis (I, II) from the group comprising the first central axis (I) and second central axis (II) enclose an angle (α1, α2) which is not equal to 0° or 90°. The sliding plane (10, 12) and the central axis (I, II) are perpendicular to each other. The first gear (4) has a first end face (14) having a first has toothing (16) that h at least one first tooth (18), and the second gear (6) has a second end face (20) having a second toothing (22) that has at least one second tooth (24), wherein a first number of first teeth and a second number of second teeth differ from each other. The first tooth (18) and the second tooth (24) engage with each other in such a way that a working chamber (26) is formed by means of a meshing of the teeth (18, 24). A volume formed by means of the at least one working chamber (26) is changed by the meshing of the teeth (18, 24). The at least one working chamber (26) is delimited by a conically shaped inner wall (30) of a housing (28). The at least one working chamber (26) can be connected to a supply flow (40) and an outlet flow (42) for the medium. According to the invention, a component (4, 6) from the group comprising the first gear (4) and second gear (6) is coupled to the housing (28) such that a rotation of the drive shaft (8) causes only the components (4, 6) to tumble. The respective other components (4, 6) from the group comprising the first gear (4) and second gear (6) is coupled to the sliding plane (10, 12) such that the respective other component (4, 6) rotates and tumbles by means of a rotation of the drive shaft (8).
