Abstract
A cylinder tube of a cylinder has an outer periphery, as taken in the circumferential direction thereof but excepting the upright surface thereof, comprising: surfaces curved convexly outward, and first to third chamfered portions, and a casing of a position detecting sensor to be mounted on the cylinder has an outer periphery formed of surfaces curved convexly outward and a chamfered portion, thereby it is possible to prevent a liquid from being trapped on the outer surface for avoiding the sanitary problem.
Claims16
A cylinder including a piston and a piston rod to be integrally displaced along a cylinder chamber under the action of a pressurized fluid fed to said cylinder chamber through pressurized fluid inlet/outlet ports, comprising:
- a cylinder tube having an outer periphery in a circumferential direction thereof but excepting an upright surface, formed of:
- an upper surface curved convexly outward;
- a pair of slopes extending from said upper surface;
- a pair of side surfaces extending from said slopes;
- and a bottom surface extending to said side surfaces, wherein:
- chamfered portions are formed between said upper surface and said pair of slopes, between said slopes and said side surfaces and between said pair of side surfaces and said bottom surface, respectively.
A cylinder including a piston and a piston rod to be integrally displaced along a cylinder chamber under the action of a pressurized fluid fed to said cylinder chamber through pressurized fluid inlet/outlet ports, comprising:
- a cylinder tube;
- a cover member jointed to an end portion of said cylinder tube for forming a cylinder chamber;
- and
- a sealing member fitted in a joint portion between said cylinder tube and said cover member,
- wherein said sealing member has a squeeze to be clamped by an annular ridge formed either on an inner circumference of said cylinder tube or on an outer circumference of said cover member.
A position detecting sensor for detecting a position of a piston fitted in a cylinder chamber in a cylinder tube, comprising:
- a detecting element for detecting a magnetic field of a magnet fitted on a piston;
- and
- a sensor body enclosing said detecting element,
- wherein said sensor body has an outer periphery formed of surfaces curved convexly outward and a chamfered portion.
A position detecting sensor for detecting a position of a piston fitted in a cylinder chamber in a cylinder tube, comprising:
- a detecting element for detecting a magnetic field of a magnet fitted on a piston;
- a sensor body enclosing said detecting element;
- and
- a detecting position adjusting mechanism adapted to be rotated circumferentially on a center of said sensor body, for adjusting a detecting position of said detecting element.
