摘要： A flow of hydraulic oil induced by sliding movement of a piston in a cylinder is controlled by a pilot-type main valve and a pilot valve, which is a pressure control valve, to generate a damping force. The pilot valve is adjusted in its valve-opening pressure with the thrust of a solenoid and adjusts the pressure in a back pressure chamber to control the valve-opening pressure of the main valve. A baffle plate is provided in a reservoir to isolate the surface of hydraulic oil in the reservoir from an inlet port through which the hydraulic oil flows into the reservoir from a damping force generating mechanism, thereby suppressing the occurrence of aeration and cavitation. The baffle plate is secured by inserting a connecting port through a positioning opening and holding a separator tube with a pair of arm portions.

摘要： A piston with a piston rod coupled thereto is inserted in a cylinder, which sealingly contains oil. An oil flow generated by movement of the piston is controlled by a damping force generation mechanism, thereby generating a damping force. A separator tube is disposed around the cylinder, and the oil is transmitted to the damping force generation mechanism through a branch tube integrally formed on a cylindrical sidewall of the separator tube. The branch tube is tapered at the outer circumferential portion thereof with the outer diameter thereof reducing toward the distal end of the branch tube.

摘要： A cylinder apparatus includes a cylinder having a hydraulic fluid sealed therein. A piston rod is connected at one end thereof to a piston slidably fitted in the cylinder. The other end of the piston rod extends to the outside of the cylinder through a seal device provided at the opening end of the cylinder. The seal device has a rod seal and a backup mechanism that presses the rod seal against the piston rod. The backup mechanism has a ring-shaped resilient member provided on the upper surface of a ring-shaped support plate clamped between a rod guide and a seal cap. The ring-shaped resilient member is elastically deformed by an annular tapered wall formed on the seal cap, thereby applying a backup force to the rod seal. Thus, the force with which the rod seal is pressed against the piston rod is kept substantially constant.
