摘要： Two separate iron cores 31 and 32, forming a magnetic path, are engaged with both ends of a cylindrical coil body 12. Each iron core has upper and lower limbs disposed in parallel with each other. Cylindrical coil body 12 accommodates a primary coil 221 and a secondary coil 223 therein, and has a core-insertion hole 4 for receiving the iron cores 31 and 32. The upper limb of each iron core is inserted in core-insertion hole 4 while lower limb extends along an outer wall of cylindrical coil body 12, so that cylindrical coil body 12 is engaged with iron cores 31 and 32 by these upper and lower limbs clamping between an inside wall of core-insertion hole 4 and the outer wall of cylindrical coil body 12. Primary coil 221 has an outermost layer formed into a dense alignment winding layer at its end part and into a non-dense alignment winding layer at its middle part. A connector la is integrally formed with a coil casing 1 of coil body 12, so as to extend in a direction perpendicular to an insertion direction of an ignitor 211 and closely to an opening portion of an ignitor housing 213 formed in coil casing 1.

摘要： A cross section of a tooth profile of a first screw rotor (17) perpendicular to the rotor axis includes a tooth top arc (A1B1), a tooth bottom arc (C1D1), a first curve (A1C1), and a second curve (B1D1). The first curve (A1C1) is a first trochoidal curve that connects a first end (A1) of the tooth top arc (A1B1) to a second end (C1) of the tooth bottom arc (C1D1). The second curve (B1D1) connects the second end (B1) of the tooth top arc (A1B1) to the first end (D1) of the tooth bottom arc (C1D1). The second curve (B1D1) is a composite curve formed by an involute curve (B1E1) and a second trochoidal curve (E1D1), which extend continuously from each other at a first intersection point (E1). A screw pump (11) thus suppresses leakage of fluid with improved performance.

摘要： A vacuum pump includes rotary shafts connected to a pair of screw-type rotors, respectively, and a pair of shaft retainers extending in the housing. Each shaft retainer supports the corresponding rotary shaft by means of a proximal bearing portion and a distal bearing portion. Each pair of the proximal and distal bearing portions are fixed in the axial direction with respect to the corresponding rotary shaft and shaft retainer. Lubricant oil is stored in an oil storage space in a gear case attached to the housing. A cooling water passage through which cooling water to cool the lubricant oil passes is formed in the gear case. A controller controls the flow rate of the cooling fluid, so that the temperature of the lubricant oil in the oil storage space is kept constant. With this configuration, when the bearing portions are fixed in the axial direction with respect to the rotary shafts and the shaft retainers, it is possible to prevent load from being applied to the bearing portions in the axial direction.

摘要： A screw pump includes a housing and a pair of intermeshing screw rotors. The housing has an inlet port and an outlet port. Each rotor has a first portion whose lead angle decreases. The first portion and the housing form an inlet space and a pump space. Winding angle of the first portion has a first region and a second region. The first region is located in a predetermined range from the end on the first portion adjacent to the inlet port toward the outlet port. The second region is located adjacent to the first region. Reduction rate of the lead angle of the first portion in the first region is set smaller than that in the second region. The maximum lead angle of the first portion is set smaller than a lead angle which decreases at a constant rate in the first region and the second region.
