A control valve (140) is coupled to a headspace (138) of the cylinder to selectively expose the headspace to a flu source (144), pressure of fluid in the headspace producing a force on the piston and valve element in a direction from the second condition toward the first condition. The compressor includes a pressure relief valve coupling (180) in the headspace to suction conditions to unload the compressor responsive to an overpressure.

The cap member is mated to the head opposite the shaft and retained by the projection.

Abstract: Methods are described for applying abradable material onto a seal backing material to form an abradable seal between rotating and stationary components of turbines using cold spray deposition technology to control the density, porosity and thickness of the sealing layer.

Abstract: A surgical suture material and a method to the use thereof are represented by different needles and surgical threads. The main embodiments comprises a needle (6), consisting of two needles (7, 8) jointed by a temporary connection having a tetrahedral, diamond or another shape in such a way that a single needle point (9) is formed, and a surgical thread (10) provided with shaped design projections embodied on the thread surface in the form of notches. The shaped design of the notches has a very important significance since it makes it possible to provide a reliable linkage with soft tissues and to forcedly holding the soft tissues when force actions are applied thereto. The method consists in introducing, during a surgical intervention, the twin needle in one puncture at a small depth, wherein the needle is divided into two needles, and in leading each needle along a required contour. The surgical suture material can be extensively used for surgical and cosmetic interventions.

A control valve (12) is controlled: (a) in the subcritical mode, so that a predetermined “subcritical pressure” ensuring a predetermined sub-cooling of the liquid refrigerant at the outlet (14) of a heat-rejecting heat exchanger (10) is maintained; (b) in the supercritical mode, so that a predetermined “supercritical pressure”, which is optimized for optimum efficiency, of the supercritical refrigerant at the outlet (14) of the heat-rejecting heat exchanger (10) is maintained; and (c) in a border mode in a border region next to the critical point, dependent on a “continuity pressure” which is determined on the basis of the predetermined “subcritical pressure” and the predetermined “supercritical pressure” of steps (a) and (b).
