派克柱塞泵根據傾斜元件的不同，有斜盤式和斜軸式兩種。斜盤式是斜盤相對回轉的缸體有一傾斜角度，而引起柱塞在泵缸中往復運動。傳動軸軸線和缸體軸線是一致的。這種結構較簡單，轉速較高，但工作條件要求高，PARKER柱塞端部與斜盤的接觸部往往是薄弱環節。斜軸式的斜盤軸線與傳動軸軸線是一致的。它是由于柱塞缸體相對傳動軸傾斜一角度而使柱塞作往復運動。流量調節依靠擺動柱塞缸體的角度來實現，故有的又稱擺缸式。它與斜盤式相比，工作可靠，流量大，但結構復雜。

Parker派克PV系列軸向柱塞泵有帶標準壓力調節器和帶功率調節器兩種選擇。排量從16至270ml/rev，額定工作壓力為350bar，轉速為每分鐘300轉，泄油口朝上。型號有：PV016, PV020, PV023, PV032, PV040, PV046, PV063, PV080, PV092, PV140, PV180, PV270等。
