摘要： An exhaust brake incorporates a slide valve with a decreasing returning or opening effort without also having an increased working or closing effort of its valve elements incorporated therein. The brake system includes a first valve piston connected to a closing slide valve and adapted to move in reciprocating motion inside a cylinder under an operating pressure supplied thereto, and in addition, a second valve piston adapted to be driven in rectilinear motion under the operating pressure in the cylinder so as to work upon a resilient member to be deformed resiliently. When opening the slide valve, a restoring effort of the resilient member is relayed effectively to the first valve piston through a transmitting member to work in assistance with the returning motion of the valve piston.

摘要： The present invention relates to an exhaust gas brake system of slide type for an improvement in construction that a coupler cover member has a space chamber defined in the inner circumference of a central opening thereof through which a piston rod of a pneumatic actuator extends, the space chamber communicating to the atmosphere, through which chamber exhaust gas from an engine liable to flow to the side of the actuator is guided to be discharged to the atmosphere. Also, the invention relates to such an exhaust gas brake construction that there are provided first ring means and second ring means disposed in an alternately stacked relationship one upon the other within and along the longitudinal axis of the piston rod passing opening, the first ring means having a relatively small inner circumference clearance and a relatively large outer circumference clearance, the second ring means having a relatively large inner circumference clearance and a relatively small outer circumference clearance, whereby exhaust gas is prevented from entering into the actuator and carbon is prevented from depositing onto the piston rod.

A single bolt member engages the lock nut and secures the bottom portion of the storage casing to the bottom end cover. A moisture sensing member is disposed in position within either the housing or bottom end cover in such manner as to monitor the moisture content of the compressed air existing in a purge chamber defined between the housing and the drying agent storage casing. A belt-like fixing member is placed around the outer circumference of the housing for mounting the air drier apparatus. The housing is provided with an annular projection or recess mating snugly with a complementary annular recess or projection on the inner circumference of the belt-like fixing member.
