| The present invention provides a screw compressor wherein, even if a gate rotor flexes owing to a temperature differential between a casing and a screw rotor during operation of a compressor, the gate rotor is prevented, with a simple configuration, from biting into the screw rotor, which reduces the amount of wear of the gate rotor and prevents a decline in the compressor's performance. The gate rotor (3) comprises a gate rotor main body (30) and a shaft (40) to which the gate rotor main body (30) is attached. An elastic body (5) is disposed between (S) the axle (41) of the shaft (40) and the hole (32) of the gate rotor main body (30). | ||||||

A seal member is provided between a rear surface of the orbiting scroll and a frame member arranged opposite thereto to divide a rear side chamber into an inner space and an outer space. The inner space inside the seal member is subjected to a pressure substantially corresponding to a discharge pressure, and the outer space is subjected to a pressure lower than that of an inner back pressure chamber to press the orbiting scroll against the fixed scroll. The scroll members are formed such that the width of a groove and the thickness of a tooth of the spiral body formed inside the seal member are larger than those of the spiral body formed outside the seal member. | ||||||

| A scroll compressor (40) comprises: housing (12), orbiting scroll (26) and fixed scroll (41). The drive shaft (14) has an eccentric shaft portion (18) so that rotation of the eccentric shaft portion imparts an orbiting motion to the orbiting scroll relative to the fixed scroll. Axial spacers (42) are located between the fixed scroll and the housing for spacing the fixed scroll relative to the orbiting scroll. When the scroll compressor (40) is assembled and tested and it is desired to perform shimming, the fixed scroll can be removed and a selected spacer placed in position prior to re-assembling the fixed scroll. | ||||||

A decrease in efficiency of a compressor is prevented which is caused by allowing two adjacent helical grooves to be simultaneously open in a discharge port. A screw compressor (1) includes a screw rotor (40), a casing (10) for containing the screw rotor (40) and provided with the discharge port on an inner peripheral surface thereof, and a gate rotor (50) having gates (51, 51, ...) meshing with the helical grooves (41) of the screw rotor (40), and compresses gas in a compression chamber (23) formed by the screw rotor (40), the casing (10), and the gate rotor (50) to discharge this gas from the discharge port. The discharge port is divided into a first port (74b) and a second port (75b), in a state of two adjacent helical grooves (41, 41) among the helical grooves (41) being open in the discharge port with rotation of the screw rotor (40), one of the two adjacent helical grooves (41, 41) being open in the first port (74b), the other being open in the second port (75b). |

In a single-screw compressor, a gate rotor (50) and a gate rotor supporting member (55) together form a gate rotor assembly (60). In the gate rotor assembly (60), each gate (51) is supported by a gate supporting portion (57) from the back surface side thereof. Each gate (51) includes a pressure introduction channel (52) running through the gate (51) in the thickness direction thereof. A back pressure space (65) is formed on the back surface side of each gate (51). The back pressure space (65) communicates with a space on the front surface side of the gate (51) via the pressure introduction channel (52). Therefore, the internal pressure of the back pressure space (65) is generally equal to the refrigerant pressure acting upon the front surface of the gate (51). This as a result reduces the deformation of the gate (51). |
