Document Type and Number:
WIPO Patent Application WO/2014/121496
Kind Code:
A1
Abstract:
An air compressor construction. Same allows an air compressor to obviate the need for a pressure safety valve to be provided additionally to allow compressed air outputted during operation to be kept within a safe pressure value range. Formed at the top end of a piston head (61) of a piston body (6) are an opening and a concavity forming the bottom wall and circumferential wall of a cushioning air-accommodating indentation (60). This allows, when the piston body (6) is moving reciprocately in a cylinder (3) of the air compressor, for all to be kept within the safe pressure value range with respect to an object that is being inflated, provides use safety, obviates the need for a pressure safety valve to be provided additionally, and reduces manufacturing costs. Also, when the piston body (6) of the air compressor is at an upper dead point while making a linear movement in the cylinder (3), a cushioning space can be found between the piston head (61) of the piston body (6) and an interior top wall opposite thereto of the cylinder (3), thus allowing the piston body applicable for such cylinder to further achieve the effect of smooth operation.
