摘要： The inflow of an external fluid into a mounting hole of a displacement control valve can be prevented, and accumulated gas in the mounting hole due to the permeation leakage of high-pressure gas can be discharged to the outside. A displacement control valve 1 inserted and fitted in a mounting hole 3 provided in a casing of a device controlled in displacement includes a sealing lip 46. The sealing lip 46 is fitted in a fitting section 41 at an outer peripheral portion of the displacement control valve 1 on a side close to an entrance of the mounting hole 3. The sealing lip 46 has a lip portion 46b abutting on an inner peripheral surface of the mounting hole 3.

摘要： A displacement control valve includes a valve housing, a valve element fitted in a guide passage of the valve housing, and a solenoid for driving the valve element to open and close it, a tapered portion is provided at one of an outer peripheral surface of the valve element and a guide surface of the guide passage, and a spiral groove is provided in the other, wherein the tapered portion is set such that a gap between the valve element and the guide passage is larger toward the low-pressure side than on the high-pressure side, and the tapered portion and the spiral groove are provided such that a starting point of the tapered portion is located within the region of the spiral groove in the entire range between the starting point and the ending point of the stroke of the valve element.
