Rotary fluid machinery

In a rotary fluid machine for converting the reciprocal movement of pistons (41) and the rotational movement of a rotor (31) from one into another by the engagement of rollers (59) and annular grooves (60) with each other, a value in a positive peak region of a pressure load of pistons (41) received...

Zusammenfassung:	In a rotary fluid machine for converting the reciprocal movement of pistons (41) and the rotational movement of a rotor (31) from one into another by the engagement of rollers (59) and annular grooves (60) with each other, a value in a positive peak region of a pressure load of pistons (41) received by the rollers (59) engaged in the annular grooves (60) and a value of a positive peak region of a centrifugal force load received by the rollers (59) are set, so that they are substantially equal to each other, and phases of the two peak regions are deviated from each other. In addition, the phase of a negative peak region of a vane (42) pushing-down load received by the rollers (59) and the phase of the positive peak region of the pressure load of the pistons (41) received by said rollers (59) are established, so that they are overlapped at least partially on each other. Thus, a peak value of a total load received by the rollers (59) and an amount of variation in the load can be suppressed to a small level to provide an enhancement in durability of the rollers (59).
