Abstract: A multiple valve spring compressor consists of a rectangular base of sufficient size to support the entire structure, an upper frame member being of a rectangular u-shape, is attached at each end to the base with an expandable device attached at it's center point. The expandable device which applies force to compress multiple valve springs is connected to a compression plate that is rectangular and has an elongated slot, the compression plate contacts the valve springs retainer during operation, upon compression of the valve springs, the stems and locks will pass thru the elongated slot for removal or installation.To align the valve springs with the compression plate, a head mounting table; which the cylinder head being worked on will rest upon, can be adjusted to various angles of tilt and pivot.
