    摘要： In a single screw compressor, gates (51) of gate rotors (50) are to be engaged with spiral grooves (41) of a screw rotor (40). In each spiral groove (41) of the screw rotor (40), an area extending from a start point of the spiral groove (41) to a position in a compression stroke is a suction-side portion (45), and the remaining portion (portion up to a terminal point of the spiral groove (41)) is a discharge-side portion (46). In the discharge-side portion (46), a clearance between a wall surface (42, 43, 44) therein and the gate (51) is substantially “0 (zero).” A clearance between the wall surface (42, 43, 44) in the suction-side portion (45) and the gate (51) is wider than that between the wall surface (42, 43, 44) in the discharge-side portion (46) and the gate (51), and is gradually narrowed from the start point toward the terminal point in the spiral groove (41).

    摘要： Present invention provides a single screw compressor from which only a small amount of gas to be compressed leaks and which can be manufactured at low costs. There are provided a screw rotor 1 having six grooves 2, 2, . . . and a gate rotor 4 having 12 teeth 5, 5, . . . which are installed in a casing. Since six, which is the number of the grooves of the screw rotor 2, and twelve, which is the number of the teeth 5 of the gate rotor, have a common divisor, only predetermined teeth 6 are engaged with a groove 2. Therefore, engagement combinations of the grooves 2 and the teeth 5 are divided into six groups. In each of these groups, dimension accuracy is controlled so that the grooves 2 and the teeth 5 engaged each other have appropriate clearances. Since manufacture is easier when dimension accuracy is controlled within each group than when dimension accuracy of all grooves 2 and teeth 5 is controlled at one time as in a conventional case, this single screw compressor becomes inexpensive.

    摘要翻译： 本发明提供了一种单螺杆压缩机，仅由少量被压缩的气体泄漏并且可以以低成本制造。 设置有具有六个槽2,2的螺杆转子1。 。 。 以及具有12个齿5,5的门转子4。 。 。 它们安装在外壳中。 由于作为螺杆转子2的槽的数量的六个和门转子的齿数5的十二个具有公共除数，只有预定的齿6与槽2接合。 因此，槽2和齿5的接合组合被分成六组。 在这些组中的每一个中，控制尺寸精度使得凹槽2和彼此啮合的齿5具有适当的间隙。 因为与常规情况一样控制所有槽2和齿5的尺寸精度时，在每组内的尺寸精度被控制时，制造更容易，所以该单螺杆压缩机变得便宜。

    摘要： A screw compressor includes a casing having low and high pressure spaces, a screw rotor inserted in a cylinder part of the casing, and a slide valve disclosed in the cylinder part. The screw rotor has a plurality of helical grooves forming a compression chamber. The slide valve is moveable along an axis of the screw rotor and faces an outer periphery of the screw rotor to form a discharge port to communicating the compression chamber with the high pressure space. Fluid in the low pressure space is sucked into the compression chamber, compressed, and then discharged to the high-pressure space when the screw rotor rotates. The slide valve includes a sealing projection located on a back surface of the slide valve opposite to the screw rotor, and separating the low and high pressure spaces from each other when the sealing projection is in slidable contact with the casing.

    摘要： A single-screw compressor includes a screw rotor, a cylinder wall in which the screw rotor is rotatably accommodated, a driving mechanism which variably drives the screw rotor according to a load, and a slide valve which is provided in a slide groove formed in the cylinder wall. The slide valve faces an outer circumferential surface of the screw rotor to be movable in an axial direction, and to adjust a discharge start position by being moved in the axial direction according to the operating capacity. A discharge side end surface of the slide valve extends in a direction corresponding to a screw land of the screw rotor to which the discharge side end surface faces when the slide valve is moved to a position corresponding to a part load operation state.
