摘要： The present invention provides an apparatus for electrically and hydraulically driving a hydraulic cylinder, including a hydraulic pump rotatable in opposite directions, an electric motor for driving the hydraulic pump, a reservoir tank containing hydraulic fluid therein, and a servo-valve. The hydraulic cylinder makes fluid-communication at a head-sided hydraulic chamber with a first port of the hydraulic pump, and makes fluid-communication at a rod-sided hydraulic chamber with a second port of the hydraulic pump. The servo-valve allows ones of the head-sided hydraulic chamber and the rod-sided hydraulic chamber to make fluid-communication to the reservoir tank in accordance with a direction in which the hydraulic pump rotates, and varies a degree at which one of the head-sided hydraulic chamber and the rod-sided hydraulic chamber makes fluid-communication with the reservoir tank, to a designated degree.

摘要： There is provided a hot melt applicator including (a) a nozzle opening, (b) a valve seat disposed upstream of the nozzle opening, (c) an empty chamber formed between the nozzle opening and the valve seat, (d) a valve body movable to the valve seat so that the valve seat is open or closed, and (e) a spring for biasing the valve body; and a pneumatically driven cylinder for driving the spring. The valve body is shaped to be a cone having an apex angle facing the nozzle opening, and the valve seat is formed with a tapered surface which is to make a contact with the cone. The tapered surface has an angle greater than the apex angle of the cone, and has a length of at least 1 mm. The hot melt applicator uses a pneumatically driven cylinder for driving the valve body to thereby compress the spring which in turn compresses the valve body, and thus, avoids the great resistance of hot melt with the spring used as a large capacity. By slightly changing angles of the valve body and the valve seat, the leakage which would occur when the valve is closed is prevented. By setting a length of the taper surface of the valve seat which is to make contact with the valve body to be in the range of 1 mm to 2 mm, the present invention makes it possible to prevent making of glue filament for a glue having great viscosity such as hot melt. In addition, setting a stroke of the valve body in the range of 0.3 mm to 0.5 mm ensures more effectively to prevent making of glue filament.
摘要翻译：提供了一种热熔体施加器，其包括（a）喷嘴开口，（b）设置在喷嘴开口上游的阀座，（c）形成在喷嘴开口和阀座之间的空腔，（d）阀体可移动到阀座，使得阀座打开或关闭，和（e）用于偏压阀体的弹簧; 以及用于驱动弹簧的气动驱动气缸。阀体成形为具有面向喷嘴开口的顶角的锥体，阀座形成有与锥体接触的锥形表面。锥形表面的角度大于锥体的顶角，并且具有至少1mm的长度。热熔胶器采用气动驱动气缸驱动阀体，从而压缩弹簧，弹簧又压缩阀体，从而避免了与大容量弹簧相比的热熔胶的极大阻力。通过稍微改变阀体和阀座的角度，可以防止当阀门关闭时发生的泄漏。通过将与阀体接触的阀座的锥形表面的长度设定在1mm至2mm的范围内，本发明使得可以防止用于具有大的胶的胶丝长度粘度如热熔。此外，将阀体的行程设定在0.3mm至0.5mm的范围内，确保更有效地防止了胶丝的制造。
